Got the trans back in today. All seemed good running on jackstands, good pressure off idle, holding 180 psi line pressure, would drop like 15-20 psi going into lockup then ramp back up again to 180. After driving a bit and getting warmed it would run like 200 unlocked and drop to 175 locked, was holding power good. 1-3 shift good, OD is kinda soft.
Then on my way home the pressure started going nuts, it once spiked over 225 unlocked, then had really low pressure under 2500 rpm. Only 50 psi in gear at idle. Huge pressure drop in lockup. Tv lever is tied open and fluid looks good. Something wrong in the VB? BTW brand new converter, new seals in the trans ect, VB was taken apart and cleaned by a local trans rebuilder. When he cleaned out the VB he did say the pressure regulator was stuck, probably from all the crap in the fluid.
