3 rd time transmission removed ,
rechecked all the internals ,all ok
still wont shift ,stays in firstgear unless I release gas pedal, and after it shifts in 2 nd gear I have to be real smooth on gas pedal ,otherwise downshifts in 1st even at 5,000$ rpm
If I can reach 50 mph, by accelerating slowly ,seems to run ok
up to now :
1) chacked my electronic shiftcontrol : perfect ( resistances, solenoïds open/ close , no leaks )
2) valve body totally dismantle all checked : perfect
3) transmission teared down again complete check ,all ok
3 months , not running ! Îm desperate
before it quit ,it was flawless

If you mean about the electronic shift control
I used a soft rubber hose 10 pds of pressure on seat ,no audible air leaks , activated each solenoids coul hear air going seems ok

No, I mean checking the clutch function with compressed air. You could have a leaking seal in a clutch and not know it unless you check that the clutch applies with air pressure.

Suite ,,,,,
brang the transmission to the biggest shop in my area
they put it on a dyno , dint shift in 2 nd and no od
problem was valve body little ***** were not at the right place ( was dismantled and all is great in there , )
recheck on dyno , works great
reinstalled tranny on RV
road test : shifts great 1-2 , when shifts in 3rd gear , a high pitch whining noise is heard
slowed down to stop, tried again , 1-2 ok , when gets in 3rd again that high pitch whining sound ,
I’m desperate ! 🥺😓
