Stuck in Forward gears

[Joeloosechange]

I have a 4r44e trans. I just rebuilt due to the Bell housing was cracked. It was shifting fine when I pulled it out. After rebuilding and reinstalling the trans seems to be stuck going forward. It was not over or under serviced all electrical connections were good. and It all so showed that the trans range sensor is working correctly (the reverse lights are coming on).

So I pulled the pan to check the solenoid operation with the key on in park all 5 solenoids are active. My rebiuld book shows me only one should have be active in P or N. Also in 1 and all other gears all solenoids have 12V.

Would this be why it will only go forward and what would cause all of the solenoids to be active?

Does it go forward in all selections including reverse and neutral? If so it will not be solenoids, there is a mechanical problem either in the valvebody or somewhere in the rest of the transmission. Either a welded together forward clutch pack or a missing or misplaced washer.

Solenoids

Why would all of the solenoids be active in all the gear selections evern R and neutral? Going to reset the computer and test the harness this evening.

Did you only replace the bell, or a full rebuild?

Could the rev. band be backwards, did you tighten the OD. and interm. bands to spec?

Did you replace the VB gasket and rev. servo gasket?


Also see if you pinched the trans harness when bolting the up the trans....
