The charts I have read suggest that I'll only get 20k - 40k out of the transmission at these temps. What is the best way to get them down?
Next service switch to synthetic fluid as you should find something compatible. And by all means add the largest stacked plate auxiliary cooler you can.
Can you tell if the torque converter is locked up at those speeds and temperature?
Ah, funny you should ask about TC lockup. I am not entirely sure how one should normally operate. In automatic cars I have owned in the past this has been noticeable as almost a small gear shift (RPMs drop by a few hundred. This thing has me confused. The E4OD has only 4 gears but I count what seems like 5 or 6 shifts, especially at lower speeds. Is this the TC locking up and dropping RPMs? I should note that there is a transcommand installed, I have been meaning to verify that all of the wiring is still good but have not done so yet.
