Still trying to diagnose the transmission shifting (OD & TC).
There seems to be no rhyme or reason as to when the transmission decides to shift into OD. Sometimes @ 35mph, sometimes @ 45 and other times @ 50 mph. Sometimes if I let off the throttle completely, it will shift into OD. Once in OD it stays. I installed two LEDs that register the ground signals from the PCM for OD and TC lockup and they both light up when driving OD 1st and TC later. I contacted DTT (I have their valve body installed) and was told to adjust the TPS to 0.9vdc and it still acts the same (replaced the TPS approx 10K ago). I have installed the DTT noise filter with no change. Just had the transmission serviced with no difference.
Any other ideas? I'm going crazy.

He has been more than helpful with trans issues on the first gen forum, don't know if he gets up here too often.
