Today, I did the CT pressure test. The CT pressures are always low. Here are the results:
P:40PSI(cool idle) 20PSI (hot idle)
R:35PSI (cool idle) 10PSI (hot idle)
D:15~20PSI (hot idle) 40~50PSI (TCC off at 50mph, most time it is 40PSI) 50~60PSI(TCC on at 50mph, most time it is 50PSI)
WOT: 60PSI (hot idle).
When the tranny in failsafe mode, it is 60PSI at 50MPH.
According to Jeff, there is an internal leak inside VB or TC. But I just replaced these two parts. Is it poosible that a poor pump cause the low CT pressures?
