Igy,
If your data is correct and your line pressure is good then you can rule out the pump.
If this was my car, I would pull the VB and test the converter regulator and bypass valves to see if they stick. Then I would dissemble and inspect them carefully for ware. The valve components are anodized and will be shinny if worn. Donâ??t forget to check the bores. Just because someone says something is rebuilt doesnâ??t mean that it was actually fixed or updated. If you are happy with the VB then check the gaskets and separator plates and be sure to reinstall and torque the bolts to the correct values and in sequence. Also check the gasket and torque of the Sol regulator assy.
From your numbers it looks like the TC is getting the command to lock (so you can rule out PCM problems) but the pressure canâ??t build to the required 80PSI due to a week valve or a leak in the circuit. Your TC could be at fault as Unisys12 is correct in noting, you can get bad rebuilt parts as his experience points out.
