So I wonder why the diagnostics is flagging a fault with your MV3 solenoid circuit?

I don't know why. anyway I just delete all EGS faults and waiting for the next diag.
I think to have some different problems with my Zf gearbox.
1. Reverse problem
2. Trans Failsafe Mode that not everyday is displayed but sometime also 15 time per hour (turn off the key and restart engine )
3. low range isn't operative

Think you that these 3 points are together?

hi Phil, after deleting ALL faults, I did another diagnosis, EGS, and it seems that the error is 32 OUTPUT SPEED SENSOR, correct? but now I also have error.N 18.

think you that TRANS FAILSAFE PROG appear due the reverse problem

However, I decided to pull down my zf transmission and would like some advice if possible.
. is better to remove complete transmission with T CASE , or T CASE before gearbox?
You think it's a problem with no lifter.
Still not sure if my T CASE potentiometer working properly.
to replace F clutch for reverse problem I have to remove all clutches, than what parts should I replace having the gearbox down to do a good overhaull work.
have you some sizes dimensions to homemade necessary special tools like your pictures : a) to extract the two jump tubes that feed the C & D clutches b) to compress the clutch springs
I would not disasseble body valve
I read many times your posts, images and advices in all forums, and I know that is not an easy work but I want to try,but nobody here with real experience, and I should send transmission over 500 miles .
