Hey have a 4055 power shift sometimes it will move but briefly. Speedometer Say's 0. Have good system Pressure b1 and pilot pressure and the rest are 0. Blocked off c1 &c2 lines no change. Tractor quit moving in the field without warning .differential lock didn't make any difference

Torsional dampener has failed???

Yes if it was an 8spd. The 15spd doesn't have one,, I have seen the bolts blow out on the High/low on these but you normally still have power through the other side of it..If the key sheared on the trans pump you should not have any hi pressure hydraulics...looks like your Gonna have to open it up to look closer...

Lift arms work and forgot to mention that b1 pressure is constant as soon as shift lever is moved out of park and to the right

Yes hydraulics work and b1 pressure is constant once shift
Lever is moved down and to the right

Thanks was just trying to make sure there was not something wrong with within the transmission control valves before I jumped in

I don't remember if that is normal or not, to have pressure in B one like that,, I will be bringing in a 4960 on Wednesday for a C2 slippage,, I will check that out..can you feel any of the shifts take place as it sets there ?? and Of course I am sure you have already checked the disconnect lever under the cab to be sure it did not slip into nuetrul...those are normally rusted in place most of the time..
