What's the best option to cool my tranny. How much better is a 28,000 GVW B&M tranny oil cooler ... than the 19,000 I currently have now ... with the Yank SS3600 stall I currently have? My new FLP tranny is running at 230-240* in 80-degree weather. Would I be better off buying a deeper transmission oil pan, instead? What's best?

I have recently installed a B&M 70298 cooler which has a 7" fan. I haven't run it during the summer yet, but tranny runs at 160 - 180 degrees currently. It wont fit in front of your AC condenser. I have mine mounted vertically in the space below the passenger side headlight. Remove the triangle shaped panel that closes off bottom of car (front of wheelwell), take out the battery, the coolant resoviour, the horn assembly (that has to be relocated), and mount it to the side of the square frame member. It is a pain in the *** to install, but it is in a good spot and a solid mount. I bet your temperature worries will be history

Last night I ordered a B&M 28,000 to replace the current 19,000 GVW. Not sure how much a difference it might make, but, if it doesn't do anything to help, then, I'll probably daisy-chain the 19,000 GVW in with the 28,000 GVW. I think there might be a heat transfer issue from the motor, as well ... so I'm looking to remove the FTRA to allow the radiator to cool more efficiently.
Anyone else seen much difference going from a 19k to a 28k?
Oh yeah ... the EWP comes with a 160* thermostat, so, yes it has one. The fans were set to match as far as I know. It was done at NLP, so, I'm sure it was done right.

Is your cooler plumbed so that it cools the fluid after it is passed through the radiator on its way back to the tranny?
Are you able to mount the cooler to the side of your FTRA? You can also start by removing the FTRA bottom plate if that is causing a cooling issue. I kept the bottom plate on and sometimes in the summer my coolant temps would start to climb, but tranny temps stayed under 200*

If you have good air flow it should help. I run TWO 24K B&Ms with my SS3800. I noticed in 100+* weather, with the A/C on, in traffic for a half hour of stop-and-go, I' d get up to more than 200*, and it was still climbing, slowly. I ended up pull off the plastic shrouding in front of the condensor, purchased another washer tank, and moved it behind a left headlamp, stretched the washer wire/ fluid harness, and bolted the coolers to the back, top of the bumper bar, so they hang off the back side, facing the condensor. Then, I enlarged the holes in the absorber, and the bumper bar, behind the grille. After all that, I could not get the tranny to get above 180*, under the same conditions. In addition, my coolant would run up past 235*, on my Autometer. After the change, won' t go above 215*, under the same conditions. It was a pain, but I bent hardlines, and moved some stuff around, but when the fans come on, you can feel air getting pulled into the holes, so I know it works well in traffic, when you need the air flow.
May seem like overkill, but, I ain' t got a problem now

I'm taking the FTRA out when the car comes back from the shop. I was thinking ... instead of daisy-chaining the current 19,000 in-line with the new 28,000 .... maybe I'll replace the 19,000 with the 28,000 which is connected ijn the return lines to the tranny. Then, maybe take the 19,000 cooler and placed it on the other side of the car ... in-line with the outgoing flow lines to the radiator. You think this would work well?

i think you should just put one cooler in front of your radiator after taking the FTRA off. Hell i bet even the 19,000 cooler would work good enuff like that and your car would run cooler also. With a itty bitty 3600 lock up converter you shouldn't need that huge 28,000 cooler.

yeah, bro that ftra is really restricting the airflow to your tranny cooler if it's in front of your radiator, you could keep the ftra and just mount your tranny cooler somewhere else. but i think 19,000 would be ok

Got my Trans Am out of the shop today. Installed the B&M 28,000 GVW tranny cooler in place of the 19,000 GVW .... tranny temp's running 25* cooler ... after some REALLY aggressive driving. I mounted the higher capacity cooler in the same place in front of the passenger side tire. The difference is that I put some spacers underneath the cooler to allow better air flow.
Can't wait 'til we have some more 80*+ days to see the real difference in traffic ... with the AC on. The larger capacity tranny cooler also seems to have brought my engine temps down, as well.
