trans cooler install help

[svranger25]

Trans temps are too high. So I'm installing a cooler from autozone. The cooler is 11 by11 and three quarters inch thick idk if this is enough can I run two inline. Can't do 6.0 cooler cause I need it done now. Where is best place to mount

[svranger25]

Any other suggestions taking into consideration I have to be done by tomorrow evening

I'd run it where the existing one is. I'm not sure if you would drop the pressure/flow too much by running two inline. Cheers!

I removed the lines and nothing came out of the cooler lines. Is there a way I can test the pump for the cooler ?

That cooler is to small....get a Tru cool max long and mount to the back of the bumper..you can also upgrade to SD 3/8" lines.

Tranny coolers also generally see about 15% of the total volume of fluid going through the tranny at any given time. The rest is dumped back into the pan. Upgrade to a deep sump with fins as well to allow for better heat transfer and cooling of all the fluid.

Good idea if you cannot keep the fluid cool enough with just a cooler...I've never needed one though..trans temp is measured at the pressure port..

Nothing came out of the lines?!? Pull the lines from the radiator and see if any trans fluid comes out from there. Wondering if corrosion from the radiator is effecting your system.

ok so i needed the truck up and running, so i got the cooler in, it keeps it much cooler than before, i think the cooler in the radiator is clogged now the plan is to find a 6.0l cooler for cheap and install it. went to the junk yard they wanted 200 bucks! is there any other cooler on an allison or something that is good too? maybe something the junk yard hasnt heard we want so its cheaper haha

I suggest going with the tru-cool 40k cooler.

Towing nearly 12k up 10% grades in 108* temps I never saw tranny temps over 185*. I also have the deep sump finned aluminum pan.
Last time I looked at prices for someone Amazon.com had the cooler for $139.
