    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?

    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

    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.

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

    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 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?

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

    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 ) 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.

    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.
    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.
