Igy,
Iâ??ve been away from the CEG site for awhile (new hobby), but I happened to see your post while looking for some info for my nephewâ??s tour.
Any how, from what I read I would say that your line pressures look good (I assume you took them from the port on the driverâ??s side with a good 0-100 lb gauge and at warm idle). If so, I would not be concerned with the pump.
Next you need to check the CT pressure. Connect a 0-100 or 0-150 max gauge to the center tap on the front of the tranny next the VB cover. You should get 40-50 lbs with the car in park at high idle. Next with an assistant and the car warm, go for a ride. Drive between 40 and 55 Mph, keep your speed steady and check the gauge. You should see 50 to 85 psi when TCC not locked and 85-100 with TCC locked.
If the CT pressures are correct but the tach shows TC slip then you still have a bad TC (not uncommon with rebuilds).
If the pressure is good during unlocked driving the and never goes over 85 when (steady speed 55) Then the TC is not receiving the command (hydraulic or electronic) to lock. The bypass clutch and converter valve should be checked as well as the BOO switch.
If the TC pressure is always low then you have an internal leak. This could be valve body or TC, loose VB bolts incorrect or missing gaskets. Or perhaps, your rebuilt VB is defective?
Give it a try.
