Trans cooler....

[SDPS]

Is there a way to test a transmission cooler to see if it has failed. I went fourwheeling with my dad this last weekend, I was pulling some hills with two fourwheelers on the back and a featherlite trailer (total combination 1300 #) My trans temp got up to 210* and held that way for the entire trip up there. So again if there is a test I can do please let me know.

I have already changed the transmission filter and fluid about 3 months ago.

Any ideas would be greatly appreciated

flush the cooler.... that about all you can do... add a larger trans pan will also help.... and lastly dieselsite.com sells the V10 trans cooler (better then diesel trans coolers)

good luck

also what years the truck... is there anything done to the truck... leave it in your signature.... also miles on truck... miles on trans?

Coolers cant fail unless they are plugged OR begin to leak. What cooler do you have on your truck currently? There are some aftermarket coolers available that are certainly better than stock and some aftermarket coolers are better than others.

Sorry forgot to fill in all my info.

I have a 2000 powerstroke, automatic transmission, stock oil cooler, the truck has 149,000 miles on all components. The truck has an exhaust, and had a chip for something like 2 weeks? Thanks for the quick response I will take a look into both of your guy's ideas

If memory serves me, the 00's didnt have the in radiator cooler and the air cooler, just the air cooler. Correct me if I am wrong though guys. I would recommend a good stacked plate low pressure drop cooler such as the Tru-Cool 4739. It's rated for 40,000 GVW and really get the job done. I have the Tru-cool 4950 model installed in my '95 and towing my 26 foot TT last week I never saw tranny temps over 200°.

I would have to dissagree, get the 6.0 cooler as it is 4 times bigger than the one you have and 1.5 or 2 times bigger than the one for the v-10. You will see almost a 40 degree drop in temps with the 6.0 cooler. Ir only requires a little modification to hook up to the 1/2 in lines and it will bolt into the stock location. Well worth it if you tow and have that lift. You should really look into getting gears done on that thing. I used to have 3:73s and it towed ok, but now it tows 10 times easier on the whole drivetrain now. I tow a 34' Sierra Sport toy hauler with an LT rail and some quads and I have 38x15.5 tires with 4:56 gears. Hope that helps.
