4L60e line pressure same in reverse as drive I rebuilt the 4L60e from my 99 Silverado 1500 4x4 and now the base line pressure is 50psi in all gears.
I used the master overhaul banner rebuild kit from Oregon Performance along with the transgo shift kit, pinless accumulator pistons, corvette servo and pin, tangos separator plate (I drilled the holes it recommended), beast sun gear shell, and electronics. I replaced the 4 pinion planetaries with 5 pinion ones and put in a new 2-4 drum since mine was warped. I dropped my pump and chipped the edge so I also replaced that with one from cyclone transmission. I replaced my torque converter with a Dalenzie (local shop).
I drove it once (won't again until pressure is up) and the transmission shifted through all the gears along with downshifting when OD was pressed. If I got on the gas a little it wouldn't shift until I let off.
Is there anything that would cause the reverse pressure to be the same as the drive pressure?
Will using a seal restorer in the fluid show a pressure bump if the problem is due to a nicked sealing ring?
I'm going to pull the pan today and check all the valves including boost valve and check *****. Is there anything else I should check in there?
Thanks in advance for any help
