2294 trans again!

So I got my 2294 all fixed up, but last night while baling I noticed more than normal hydraulic system chatter when I was turning around. The noise got worse and seemed like it was coming from the remotes, but before I could investigate it very much, I lost steering, the hitch, remotes and all drive gears. I can hear the switches on the circuit card clicking but the trans does not make any sound when the inching pedal is depressed. What controls everything? Is it internal?
 

I could really miss the mark on this one but it sounds like you lost your bevel gear drive set that drives all the pumps. It is internal but doable.

IIRC you have to remove all pumps including the charge pump and its body from the tractor. I believe you must take the PTO casting off to remove the gearset.

You need a factory service manual to achieve proper setup of the new gears. It is my opinion that the noise was the gearset grinding up and it could resemble a hydraulic noise.

Hopefully some others will chime in and maybe I am off base but losing all hydraulics seems to be consistent with loss of pump drive.
 
I'm with mel. I would check charge pump pressure to see if
anything is being driven, I have heard of the piston hyd. pump
input shaft snapping off but never seen one. If there is no psi
at the charge pump remove the trans cover behind the
PowerShift valve to Examine the pump drive gears.
 
Hi Karl

I agree with Mel,because you lost steering.It can be done by removing pump&charge pump and pto unit.I have done few of them.

I bet you will more than likely find bad gears as Mel has mentioned. But before jumping to conclusions, I would pop the steering pump off the end of the pump stack and crank engine to see if the main pump shaft is turning. If it is not, pull the cover off the trans as Eric mentioned and inspect those gears. And they could be good, I have seen the splines in the flywheel that drive those gears worn out. If it is turning, then there is a issue with the charge pump. More than likely a sheared drive key in the gear. A non operating charge pump causes the loss of all hyd systems and noisy cavitating pumps also.
