Transmission Cooler for the 6.0

[lcducote]

I recently put a new tranny in my 2002... its the 4r100 auto. i was curious if upgrading to the 6.0 tranny cooler would help in keepin the temperature down.. also has anyone had any luck with a 6.0 intercooler swap on their
7.3's?

I haven't done it myself, however ive never heard anything bad about either mod. The trans cooler i believe is way bigger on the 6.0, not sure about the amount of temp drop, but i think its pretty substantial. The IC, some feel its not really worth it, you get about 50 to 100* lower egt's with it. However, if you can get a 6.0 IC cheap enough, you can sell yours and come close to even, at which point i would think its worth it. Ive been lookin for both of these things myself.

yeah well i know that suncoast 4r100 transmissions are shipped to the door with a replica of the 6.0 transcooler so i imagine it it a must have... maybe i can steal it off my dad's truck.

The 6.0 is a must for any 4r100 used for towing!! Dropped my temps by 40 degrees and it's the only cooler I have. My early 2000 didn't have the OTW cooler. As for the IC, don't do it unless you get one for next to nothing!! You will only see 50 or so degree drop, not worth the cost of the TC. There are far better ways and cheaper to control EGT's.

I put a aftermarket cooler on my 01 and it seems to work great. Couple 100 covered the cooler and the installation. It seems the 4r100 needs the extra cooling. Mine went out at about 50K and ford paid 1/2 for the new one. Should of held out for full replacement but didn't know at that time that they knew they had problems with these transmission used for hauling. 100K miles now and all seems to be good. My suggestion is get the biggest cooler that will fit up front that you can find. good luck.

There are options other than the super expensive 6.0 cooler. If the 6.0 cooler was cheap enough it is the best solution since it bolts in place of the OEM cooler but the other option is a Long true cool max which is about 120 bucks. That cooler along with the OEM cooler is equivalent to the 6.0 cooler at a third of the cost.

Additional transmission cooling is a must have while towing with the 4r100 and the PSD.
