Hey, with regard to measuring pressure, the transmission has no way of measuring this. With regard to the TCM, my guess is they are stabbing in the dark. I would expect some errors from GT1 if there is a problem. It's very hard to diagnose what the problem is without being there. Sorry I can't be any more help. If you have changed all the seals, there is probably some electrical issue. Maybe one of the solenoids (they often don't throw codes when they fail). If everything is correctly put together correctly, I would be very surprised if it's a mechanical issue.
do you still remember me ?
I'm Andri, I have ever asked you about my transmission problem.
I need your advice again, I have open my gearbox and the mechanic said that my transmission didn't have mechanical problem but there is just small leaking at the bottom. OK, I decided to change all seals, speed sensor and turbine sensor.
If after the transmission placing back to my car and the gear doesn't shift properly then my mechanic advices me to replace the TCM module (EGS).
My question is, why the module need to be replaced whereas I didn't get fault report anything from GT-1 ?
Is it possible the EGS detect low oil pressure in my transmission ?
