4l60e electrical problems I have a newly rebuilt transmission which is to replace 2 other transmission that failed because of a tcc regulator valve said stuck open. So it acted like it was in 4 th gear all the time. Well i tried telling this person who had a electrical short that i couldnt locate , that this could cause some of your troubles if not all of them and he needed to find it somehow before he spent money on more transmissions. But nope and same problem , so this tcc solinoid is hot and ground pcm controls thr ground and i could possibly jump off wire going to that a supply it with a ground temporary to see if itll close the valve or should just put in a valve called fix all .

Brake switch I was just thinking if the brake switch controls power feed that controls tcc regulator valve then why is tcc valve stuck open, is valve bad i dont think so i looked and increased spring pressure slightly with a transgo shift kit and valve looked fine i believe its still this short that feeds that circuit sending mixed up signals. Can i be right or what do you think i could to fix this , i reccomended to erase tcm module and reprogram it. That might help if its stuck on this code or do i have bigger problems.

The converter regulator valve cannot make it stick in lockup , It stuck could only cause no or slipping lockup, The TCC enable valve in pump would need to be stuck or TCC solenoid stuck on , Check if the TCC SOLENOID is always grounded.

Out off touch I’m only writing to say I was the one who rebuilt this, and I went back in this and checked every detail. Then I had a old TransGo shift kit but some parts were gone so to instructions I drilled separator plate feed holes 3-4 tcc regulator valve put in a check ball to keep it from staying open I thought. But now idk what the heck is going on the other transmission before had similar problems and he did have a short somewhere which this circuit did feed the one going to transmission. So what could cause an enable valve to stay open it just acts like it’s in overdrive all the time the old trans overdrive clutches were smoked. So I assumed I was missing rear ball insulated so thought I found it but now nope. Please don’t beat me up I use to work at shop and went to school but it’s been 25yrs so I’m out of touch but thought I had it. Thanks

Let's, start from the beginning. Have you put a scanner on it to verify that's the TCC solenoid is energized, that it is stuck in 4th gear or looked at TCC slip? Have you check that fluid can flow through the TCC solenoid?
I am not sure of what the trans is doing by your description. Does it stall the engine when coming to a stop? Does it up and down shift through all 4 gears?

I thought I seen where it was controlled thru brake switch and it’s hot and ground but pulses ground, so I thought feed it a ground wire see if I can get it close. If not I have to pull it out and take pump out but it was newly rebuilt pump this was it first time in that truck. But he did have a short somewhere I thought it was near back windows lock. But couldn’t find it can this cause a tcc regulator to stick open , cause I think it could cause a lot of problems in the this area

Also the 4L60E HAS NO OVERDRIVE clutches I assume you mean the 3-4 clutch set? overdrive is actually the band coming back on after 3rd gear.
Still i would check that the TCC ENABLE VALVE is not stuck or installed backwards.
