hey guys I just did this and sooooo far it is running cooler. I am getting ready for the summer heat waves:smt077.

This is the B&M 70268 7 1/2 in. x 11 in. x 3/4 in 13000BTU and 19000GVW


here is the stock cooler and how it is positioned on it's mount
http://i31.photobucket.com/albums/c367/djjordache/cooler/bmnormal.jpg

heres a pic showing that the input and output ports line up perfectly to the stock cooler
http://i31.photobucket.com/albums/c367/djjordache/cooler/bmports.jpg

showing the difference in size! the B&M is almost 2x. which one would you rather have cooling that 42re that costs around 2K to rebuild?
http://i31.photobucket.com/albums/c367/djjordache/cooler/bmsize.jpg

here it is installed all I had to do to get it spaced correctly was to drill 2 holes in the B&M mounting plates and flipflop one of the stock cooler holders and use 1/4" bolts to hold it to the clamps:D
http://i31.photobucket.com/albums/c367/djjordache/cooler/bminstalled.jpg

this was probably one of my easiest upgrades and required almost no fabrication to fit=)

I will soon be adding another temperature probe to be able to see the temp of the output of the tranny as well as the input I already have and then just a flick of a switch to pic which sensor I want my Autometer to show.

That's funny. That's the same cooler I'm using except I attached mine to my A/C condencer and ran it in line with the original cooler. The A/C sucks like always but being sweaty is free, not transmissions.

It's amazing how much cooler a tranny will run with a better cooler, I'd argue it's one of the reasons my tranny has survived the abuse so far, that and amsoil.

It's amazing how much cooler a tranny will run with a better cooler, I'd argue it's one of the reasons my tranny has survived the abuse so far, that and amsoil.

exactly and I also have a extra transmission filter inline on the cooler lines before the coolers to make sure they don't clog up and the fluid is EXTRA clean. It uses a large Wix hydraulic oil filter. We have this setup on EVERY one of my familys vehicles.

for example of how well this filter setup works: have you ever heard of a 85 era Chevy 700r4 going over 80,000 without dying? The one in our old Suburban went 240,000 before it started to noticably slip and we had it rebuilt b/c we didn't want it randomly crapping out on us. When the transmission guy opened it up he could not believe how clean it was! It really was super clean inside and the only reason it was slipping was b/c the friction plates were running out of material after 240K miles:D

B&M looks almost 3X as much cooling. It has 3X the fins and twice the area. I wonder what the BTU of stock cooler is? Great install! Can you give me a little more info on your filter and temp guage installs?

Thanks Again for great writeups!

I just ran outside and took some pics with my camera phone my real camera was destroyed long story short with my dads model airplane crap (not the little crappy ones, this one was a 50lbs all aluminum one with a 8foot wingspan) and him running one right into me knocked me on my butt got all cut up and dropped my canon RIGHT ON THE LENS:mad:! I was more pissed about the camera than my cuts oozing all over the place.

anyways since a pic is worth a thousand words:D
I'm going to reroute the hoses but here it is of now:
the filter input side:
you will see that it goes into a tee where the fluid shoots right at the temperature sensor and then into the filter which is a WIX 51551 Hydraulic filter.
http://i31.photobucket.com/albums/c367/djjordache/cooler/filterinput.jpg

here is the filter output side
http://i31.photobucket.com/albums/c367/djjordache/cooler/filteroutput.jpg
I'll have to dig around to see if I can find a part number on the filter mount, but it's pretty much a remote oil filter mount. The filter is the same OD as our stock 4.0L ph16 or ph8a(loinger) filters but has a larger center thread hole than our oil filters, so there is no worry about flow restriction with this filter. and the Autometer transmission temp gauge is in the A pillar gauge pod.
I just like to think of it as added insurance on the transmission:D

edit I got the pics backwards

Thanks for the really great writeup! I do have a question, when's the best time to it - when replacing the radiator or is anytime a good time?

I ask because my 94 ZJ 4.0 with 192k miles is leaking alittle around the stock tranny cooler and I figure I might as well upgrade to something larger. However, I'm still using the stock radiator which I know I should replace one of these days. If it'll make more sense to replace both at the same time, please let me know!

Thanks. :D

Does not really matter, might be a little easier while doing the radiator but really about the same.

LouisianaZJ

on a side note, you can use the stock tranny cooler as a nice little power steering cooler. just plumb it into the return line that goes into the bottom of the PS reservoir

nate
09-11-2006, 09:46 PM
That's where my B&M is. I never had an additional cooler. I've had mine for 3 or 4 years now. Also have a power steering cooler, which is mounted in the stock "bumper" channel.

10-11-2006, 08:06 PM
Alright, after much procrastination, I've finally going to order the B&M tranny cooler along with a 3-row radiator from Radiator Barn. Should the tranny cooler by-pass the radiator or should I continue to go through the radiatior?

Thanks! :smt023

Not to doubt or second guess your advice, but how come? I'm curious to know. Thanks.

Cue-Ball
10-12-2006, 01:49 PM
There are a couple of reasons that I can think of off the top of my head.
1. That is the simplest way to make the swap as that is how it is already plumbed.
2. if you bypass the rad. you will decrease the amount of ATF fluid in the system (the more the better).
3. You can NEVER have too much cooling for the trans.

NCXJ
10-12-2006, 02:00 PM
just a thought, but the a/c condensor makes a damn good trans cooler as well(just needs to be plumed for the lines), and from the junk yard, they're only around 15-25 dollars, and they can be squeezed infront of or behind the setup your running now.

For the best possible cooling be sure to use Amsoil full synthetic ATF!! :D

10-12-2006, 07:18 PM
Yeah I got a p/s cooler from a Ford or Lincoln car of some sorts. Was brand new, still in the box too. Was helping a guy move and he was going to trash it.

Then I took a hole saw and cut holes in the stock bumper, which happens to be in line with the pass side hole of the ARB bumper. It's not the "best" place for it, but I had it mounted in the front of the radiator before, and all the plumbing for that plus the trans cooler, winch wiring, etc made too much crack packed in one spot.


ooooo I like that idea, I'm adding that to my to-do list that is a mile long......

that last pic in my first post is the best one I have right now of the lines but you can take a look behind the grill and see yours commin off of the stock cooler. the 4.0L has the input and output on the same side, the v8 has them one on the side and one pointed down

11-01-2006, 08:17 AM
I converted my stock trans cooler to a P/S cooler & installed a larger tranny cooler beside it & it worked sweet

alot of people have no idea how hot a powersteering system gets especially when cranking a locked set of big tires back & forth


Quick note, always run the output line from the tranny to the rad first, then from the rad to the aux cooler (i believe the output line from the tranny goes into the bottom of the rad, then the top tranny line would go to the cooler, but i always just have someone start the engine with the trans in nuetral to check which line spits fluid)
That way the 200 degree rad cools the fluid some then the aux cooler cools it down further before sending it back to the trans



Since our chrysler trannys take ATF +3 / +4 can you run straight amsoil ATF without any issue?
Or are you putting additives in?

yeah I checked a while back and there are no numbers on my mount. mine is off of heavy construction machinery (excavators, motograders, dozers, etc)
but on summit there a few are universal kits that will do the same, just make sure to use a hydraulic filter which is much more fine at filtering than a normal oil filter. mine are WIX 51551(IIRC) but it is also a larger ID for the threads than a normal filter. search on summit for "remote filter" and there are a few kits under $40

What about air flow problems through the radiator, now that you've blocked a larger portion of radiator? Also the new cooler may have more tightly packed fin area but for that reason it probably has a higher resistance to air flow.. anyone notice any higher engine temps as a result?

DJJordache
03-03-2007, 04:16 PM
there was no difference in engine temp for me....and it is not "blocked" it still flows air through it.
I guess you could say it could possibly be an ounce cooler since the trans fluid runs through the radiator also that if the transmission fluid is cooler then the engine coolant might not be heated up as much by the trans fluid:D stretching I know haha

LouisianaZJ
03-05-2007, 07:34 PM
he is on the forum, but he did not mount the bling tranny cooler on the radiator. he put it in the back cargo area of his chopped ZJ

i think you should go for a 10"x12"x 1" cooler and mount it in front of the radiator

if you are concerend about airflow to the radiator, just space the cooler 1" away from the radiator and if will dramtically reduce the effect of the reduced airflow from the large tranny cooler

kd6zxe
03-05-2007, 07:52 PM

RBall151
03-07-2007, 01:32 PM
This is only for the ZJ right? I haven't taken a look under my WJ yet.

On my WJ FSM it states:
"An internal high capacity/high efficiency cooler is used on all vehicles these coolers are an oil-to-coolant type which consists of plates mounted in the radiator outlet tank. Because the internal oil cooler is so efficient, no auxiliary oil cooler is offered."

The 3" is way too deep. The 0.75" is the perfect size...any deeper and it would be too tight.

I installed the 11" x 7.25" x 0.75" a few months ago in my '95 ZJ 4L. To attach I used the supplied plastic-pulls through the air condition condenser as I was installing a new radiator so it was easy for me. If I had to do it again I would find the brackets that wrap around the A brace to secure.

I bypassed the radiator altogether, had no problem with trans slipping or bad shifts even in -6 degree weather. I don't think trans fluid could ever be too cool.:o

RBall151
03-26-2007, 04:04 PM
Where can you get a mount to hold the cooler if your Jeep doesn't have an existing one on there?

Have any WJ guys out there done this?

JohnnyV
03-26-2007, 04:34 PM
Got your PM RBall151!

My ZJ did not have a factory trans cooler.

As mentioned I used the plastic locking ties that was supplied with the B&M trans cooler. But it was a no-brainer as I was installing a new radiator so it was easy to run the ties through the AC condenser.

But I guess what you are asking is how to mount the trans cooler without removing the radiator. Somewhere in this thread there is a picture of a simple bracket the wraps around the A-frame supports and that gets screwed into the trans cooler. I might relocate my trans cooler and use that method. Any good hardware store would have the brackets.

Oh the pictures of the bracket is from the first post...that A bracket is part of the jeep:

JohnnyV
03-26-2007, 04:45 PM
OK I see the clamps (I called brackets) are part of the original trans cooler. That's not a problem. Go to the hardware store and find a metal strap that holds up sewer pipes. The strap is about an inch wide and has holes every inch or so. Just cut and wrap around the A-Frame and bolt up.

Hey I'm thinking about putting in the factory tranny cooler. I also have a hayden fan I want to install, so the bigger B&M cooler is probably too big to fit the fan and the cooler. DJJordache, I noticed you're in houston, to you happen to have a good chrysler parts supplier here? I guess I'd be looking at parts #1, #13, 2x#7, and is it #8 that is the actual tranny cooler? thanks

nate
05-22-2007, 04:56 PM
Just get the thin B&M cooler, the 3/4" one, it's like $40. Some P Clamps, some hydraulic line, hose clamps and that's it. I wouldn't even waste my time with the factory stuff unless you can get it for cheap like in the junkyard.

Cue-Ball
05-22-2007, 04:59 PM
The B&M one actually comes with a length of hose and hose clamps (not sure it it is long enough or not though).

I simply replaced my stock one with the B&M. One of these days I will install the stock one and use it as a PS cooler.

i just got a quote for the parts using the original factory cooler;
#1 $22.77
#13 $30.64
2x#7 $9.05 each

transmission cooler
$95.53 52027796

seems a little expensive, anyone else have a better place to get parts in the houston area?

No way I would spend that kind of money, go with the B&M you will be happy with it, trust me.

i agree the B&M is bigger and probably more efficient than a 10 year old designed tranny cooler, also comes with almost everything u need to install

Yep go for the B&M. Got mine a jegs.com for about 40 odd bucks.

Off this topic, but related - would this B&M be overkill for cooling the power steering fluid? I suspect not, but wanted to check.

Every little bit helps! Go for the smaller B&M cooler 130-70255 (11'' x 5-3/4'' x 3/4'') for the power steering.

I installed on my 95 ZJ Laredo, model 130-70268 (11'' x 7-1/2'' x 3/4'') for the tranny.

just ordered the 11x5.3/4x3/4 B&M for the tranny, benefit of it getting to the shop tomorrow and including all the mounting stuff. In the end cheaper than the factory stuff and a better cooler overall. I didn't go for the 7-1/2 because i want to add a 10" electric fan ive already purchased and the bigger one would get in the way, i believe the fan will add more cooling than 2"x11" of radiator.

damn this thread got busy since I last checked at work=)

You will be happy you ordered the B&M since it DOES cool much better than the stock one I had a gauge before and after so I know it was better.... I just can't remember the temp numbers right now.

Are you planning on putting the fan in front of the radiator?

No I don't know of any great parts places around houston, I just get mine from a local dealer and they usually have it there or get it in a few days tops.

yea im going to try to mount a 10" hayden fan in front of the radiator, see this thread http://www.mallcrawlin.com/forum/showthread.php?p=144827#post144827
im also going to work on making whatever my results are into a kit with instructions and all.

There's not enough room in the front for a fan unless you pull the A/C condenser.

for the fan i bought i believe there to be enough room between the radiator and the front grill.

That is hard to believe. It is pretty freakin' tight in there.

If there is no AC condenser then there should be some room, but if there is then I can't see installing a fan. There is just clearance for a trans cooler. The depth from the AC condenser to front grill/brackets is about 1+ inch.

Will the B&M (B@M) Cooler still be alright for cooling the tranny if I bypass the radiator?

My new Griffin radiator doesnt have a tank for transmission cooling.

Anything comparable to the B&M that I can buy locally at say, Napa, or Autozone that will do the trick?

I've bypassed the tranny on my '95 ZJ when I first got it and it's been going strong for almost 4 years.

>Anything comparable to the B&M that I can buy locally at say, Napa, or Autozone that will do the trick?

My guess is- if it looks like a B&M cooler it probably is or came from the same manufacturer.

Johnny - do you monitor your trans temps? What about towing?

I'm not busting balls in the least. Just seeing if it's truly beneficial to bypass the in-radiator trans cooler and only use the external.

Checker Auto sells that B&M cooler. It's kept on the shelves here in SLC, I assume it would be there as well.

I went to the junkyard to get a hood and some head rests today, they had a few new trans coolers in new boxes, I found one for a Voyager that will fit the bill.

I was thinking, and did some researching and asked some questions to confirm my suspicions. The in radiator "cooler" is actually a warmer, the tranmision fluid travels through it to warm up to opperating temperature faster. By bypassing the in rad tank, and just going trans->cooler->trans, the fluid will 1, take longer to warm up, BUT 2, stay cooler overall. In an area with very low average temperatures, this would be a problem, and some ad thermal in line switches between the cooler and trans, forcing to fluid to get to a set temp before traveling forward to the cooler. Like a thermostat, but for transmission fluid. Simple enough.

Dang... wrote a whole damn story only to get a login window on Submit and all was erased. Not figgin happy!

Anyway... let's try again but shorter story.

No problem. I've asked the same questions before installing my tranny cooler.

No I don't monitor trans temp or tow. But my buddy here at the Jersey Shore ( fist-pump :rolleyes: ) does and after many years he's had no problem. Also others convinced me bypassing was the way to go. At the 4 year mark I believe I've made the best decision for me.

There's two camps. One believes the tranny performs best as fluid is warmed by the radiator.

The other camp believes the cooler the better for longevity and will not affect performance.

A couple winters ago, here in NJ, we had a couple single digit temps weeks. To make a long story short. Started my ZJ up in 4 degree temps, waited 30 seconds, and drove off with tranny shifting and performing normally. After that I really stopped worrying that a too cold tranny fluid is not good.

The 3" is way too deep. The 0.75" is the perfect size...any deeper and it would be too tight.

I installed the 11" x 7.25" x 0.75" a few months ago in my '95 ZJ 4L. To attach I used the supplied plastic-pulls through the air condition condenser as I was installing a new radiator so it was easy for me. If I had to do it again I would find the brackets that wrap around the A brace to secure.

I bypassed the radiator altogether, had no problem with trans slipping or bad shifts even in -6 degree weather. I don't think trans fluid could ever be too cool.:o

Do you by chance have the model number to the cooler you got ? I'm prepping for Tucson AZ heat and want to give my transmission all the help it can get.

true and I'm still running the same cooler right now.
BUT I'm going to swap it out for this one: Derale 13503
https://www.amazon.com/gp/product/B000CJ262Y/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
the rated GVW BTU rating is MUCH higher on this Derale unit than the B&M one for about the same size and it should mount up about the same way as I did the B&M one
