I have a tuned ECU from Diablosport which I use since I bought this truck with 0 miles on it. So the gear timing is faster and better for our mountains here. I guess they also changed the oil pressure in the transmission...but I do not know it. It is always a secret what Diablosport really did. But it works till now the 120.000 miles perfect for us here in Germany.The only other thing I've heard fail is the OD clutch itself, from being beat on. If you don't beat on it - i.e., use the tow shift program and lock out of double O.D. (6th 'gear') when towing, it should be fine.
Then get the oil temp down by getting rid of the oil thermostat.
Keep in mind the replacement valve body requires a PCM re-learn, it must be re-set either by dealer or your choice of tuner. Guys have had good luck with HP Tuner.
By the way: The oil temperature is measured was the engine oil (226,4°F), not the transmission oil. That is maximum at 162°F...in 4th gear with low speed (50mph).
I will get rid of the thermostat for sure.
Thanks for your help.
