Low line pressure after torque converter replacement?

I haven’t known if that was a possibility. Sure seems like it. Brand is Power Torque from O’reilly.

Low line pressure after torque converter replacement?

Debris affecting pressure has been the problem. Not so much in the Pressure Regulator valve. But I keep getting trash in the EPC solenoid screen, reducing the signal to the boost valve. There was no trouble with trash or pressure before the TC replacement. But debris must have been broken loose...

Low line pressure after torque converter replacement?

New trans filter hasn’t helped. I now have line pressure of 60 psi in all positions, idle or throttled up, trans connector hooked-up or unplugged.

Very good question, and yes, TC spun all the way into place perfectly, before mating trans to engine. Then, TC pulled back out approx 3/16” when bolted to flex plate.

Low line pressure after torque converter replacement?

I might have been misleading by bringing up the P1870. That was included simply as my reason for replacing the TC. I’m satisfied on that issue. The TC is now locking up fine. The valve repair kit, pwm solenoid mod, and tcc lockup solenoid replacement were all done, with no help for the lockup...

Correction: also changed at the same time was the neutral safety switch, though that seems to be working fine, and I don’t see how that could have an effect on line pressure.

Sure, already installed that valve kit. I’m satisfied on the P1870 code now. Just unsure why I would have lost line pressure after installing a new TC.

Low line pressure after torque converter replacement?

1997 GMC Yukon 5.7 4L60E. All stock. Transmission has been solid as a rock except for P1870 trouble code. I monitored that and sure enough the code would set when the converter couldn’t hold lockup. Narrowed that problem down to either the converter itself, or the small o-ring on the end of...
