Transmission getting to hot

[badassfx4]

When I am towing my travel trailer my tranny gets pretty hot when I go up steep inclines like in pa. mountains. I have seen temperatures around 210 as per my edge display. My truck has the factory tow package with the heavy duty cooler, and I changed the tranny pan to a deeper b&m aluminum pan with royal purple max synthetic and it still runs hot. I was thinking about replacing the factory cooler with a derale atomic cooler. Has anyone done this, or know what I need for fittings etc.

when your towing do you have the OD on or off? if you leave it on you are putting huge loads on the engine and trans. i had a tech 2 on my truck took it for a drive the engine was under 90% load doing 40 in 4th i took the OD off i think the truck went to 2nd or 3rd but it then only had 20% load. OD puts a very big load on the engine and trans and will cause them both to get hott if towing in OD.

as for an aftermarket cooler are you going replace your stock one or add another one along with your 2 stock ones? what ever you do do not take the trans lines out of the radiator the coolant going by the trans lines helps keep the temp under control built54 told me he took it out of there and put it to a big cooler and his trans temps went very high untill he put it back threw there.

i would say fallow the inlet line to the cooler coming out of the radator. then un hook the trans line on the outlet of that cooler find what size line it is get some fittings and some more pipe pipe it to the other aftermarket cooler then back to the trans. ive done this once before on a bronco helpd out alot!

hope this helps!

Imo, 210F is not too bad if that's the highest temp you've seen while towing. I installed Troyer's Active Trans Cooler in my '00 4.6:

and it really dropped the trans fluid temp! I rarely see 180F now and when I do the trans cooler fan kicks on and brings the temp down quickly. (Trans temp. as reported by ScanGuageII.) When I installed mine, I bought some extra rubber fuel/oil line to locate the cooler where I wanted it. Other than that, the kit has everything you need. There are other good coolers out there, too. A search of this site will turn up a bunch of 'em.

Also, as mentioned above, stay out of OD and choose a gear that keeps your TC locked to keep everything as cool as possible.

yea PA mountains suck. I had my trans up to 215 and I wasnt towing anything, just my truck..... Key is to hit those hills at a very very high speed, faster you can climb the hill, the less heat you'll build. after the hill you'll lock the converter and temp will DROP

CTC, you ever been west of the Mississippi, flatlander? PA mountains are mere "hills".

I always tow with OD off, I want to replace the cooler in front of the radiator

I'd look at the Troyer cooler.
