Did anybody eliminate the stock heat exchanger and tranny cooler and replace it with something else? Im thinking a larger tranny cooler with its own fan. Best way to describe it I guess. This is on my 98 12v. Thank you in advance. Brian
 
Yes, several have done that. Works great. The one on the side of the block is only a cooler if the engine coolant temp is less than tranny fluid.
 
Did you do this? What kind of cooler did you use or did you use a stock one in front of the rad? Whats your setup now I guess is the easiest question. What you kept, eliminated etc.
 
I used one from summit, I think it is a B&M. I removed the whole factory setup, the plugs on the side of the tranny a 1/4" NPT if you take the adapters out. I used hydraulic hose and mounted the cooler under the drivers side floor board, put some steel mesh to protect it. This is a pulling truck only. On a street truck I would keep the front one on the radiator.
Leave the front port on the tranny, go to the front one, then go to the one with the fan. Some of the coolers have a built in temp switch.
 
Derale makes some nice coolers which is what I used. Don't know how the set up is on a '98 but, if it's the same as the newer trucks with the aux cooler on at the back of the block, you can remove everything from the front cooler to the trans and replace with what you want....

i took the one off the side of the engine off of mine about 3 years ago. left the one up front, works fine for me. j
 
I did the Derale Atomic cool under the bed like triton. I drove around with that for a couple days, and I didnt like how warm the trans was getting. I thrn added a B&M super-cooler in the stock location in front of thr radiator. That REALLY dropped the temps.

I just got back from camping and my trans guage would read 150* while doing 70mph pulling our 11k camper.
 
I'm running just a big Derale cooler as well, not impressed. I'm going to tie one in up front like you did and hopefully that will help.

did you completely replace the stock cooler with the B&M ? I thought of doing that too until I saw it was only psi tested to 200psi. I'm running 220psi ... at the trans anyway. I would imagine that psi would be though the system.

I just did a manual to auto conversion. I didnt have any coolers to begin with. The B&M piece is alot stouter than the stocker. The guy I swapped with sent the stocker and I wasnt to impressed.

I cant get over 180* running all over town in 98* weather with the two coolers.
