Can I eliminate my front transmission cooler and just put a big one with a fan and thermostat under the bed?

Yes.

My lines are currently looped into one another because we couldn't find a good spot for it after the PS intercooler install.

I towed my camper 155 miles up to Billings on Friday and temps still didn't go over 165* in the pan, so its okay for now. Summertime would be a different story though.

I'm not going to leave it like this forever. I still have to figure something out.

I'm running the ps intercooler as well. I just have the stock cooler setup in my engine bay for now. I'm going to put a larger derale cooler/fan under the bed and see if I can eliminate the original tubing to the front for a cleaner look. I will also be installing temp gauge and I picked up a b & m pan.

Except for the airflow, It seems kind of dumb to have the front cooler anyways because of the long length of line needed to get the fluid up there and back. The optional cooler makes more sense to me.

OMG i hate that heat exchanger. when doing the 5-speed swap to my friends first gen that thing took more time to take off then everything else combined!

goodluck my friend! haha

Advantage/ disadvantage kind of thing. In cold climates it helps warm the transmission. In warm climates it's in the way changing oil filters.

Just buy a nice cooler with a thermostat

Had to pull this old post up. I too did the power stroke inter cooler years ago and removed the ATF cooler for space reasons. I actually saved it by reinstalling it directly under the drivers door and oriented it to catch under cab air while driving. This set up is combined with a derale cooler w/ 10" fan under the bed. That thing comes on when my gage hits around 175 degrees. So along with the fluid to fluid cooler under the turbo I have 3 forms of ATF cooling. Well, 4 if I count the auxiliary ATF external filter that also acts as a heat sump. My question is after around 20 minutes of city driving my temps shoot up to start the cooler fan. So from parked overnight to 20 minutes down the road, bam! ATF temps up to 175-180. New ATF, too, and never under or over filled. My idle is around 750 w/ a/c on. Is there some adjustment at the tranny that I'm missing? I do have the tv cable slightly adjusted out of spec to firm up the shifts. Also adjusted the bands to spec when I replaced my ATF 5,000 miles ago. In this Bay Area traffic of stop and go sometimes my gave creeps up to 210 degrees. I put that thing in neutral for a few and the temps shoot down to 180

The biggest heat maker in an automatic transmission is the torque converter. If you are in heavy stop and go traffic it's going to make some heat, nothing you can do about it.

To minimize it though you can slip it into neutral at stop lights and such, I do that a lot.

Did the tranny cooler you added have the 1/2" ID tubes? That is also necessary as the smaller ones really restrict the cooler flow.

Yes 1/2" OD tubes for sure. All my ATF hoses to the cooler n fan combo along with the front cooler reroute are 1/2" ID oil rated hoses with pushlok fittings. The only exception is the auxiliary external ATF Baldwin filter set up, where I blow up from 1/2" to 3/4" to the filter and back, and at the reconnect to the OEM lines I transition back to 1/2". Got to do that to make up for the restriction that filtering causes. So is it correct to assume with the hot weather we have all you guys are hitting 180 degrees within 20 minutes of bumper to bumper traffic, with no load being hauled?
