Sunstrand torque question

[Ed Kennell 38,684]

.Set up my 90-1140 tranny for testing similar to squonks set-up on his post "way to flush a trans and hyd lift".

The tranny just lost power in my 16 auto, so I replaced it with a 90-2046 from my Charger 12 parts horse.

The tranny seems to operate OK forward and reverse.

My question is with both axles locked with the yellow torque bars, if I put a scales under one bar , what torque should a good tranny develop ???

I am not aware of any torque development specs. I would suggest you do a charge pump pressure test (see the sundstrand manual) Should get 70-150 psi.

Is this a hydro gear or piston to piston ( I can't see the motor head in the picture to tell)?

I think it's a hydro gear. Did the pressure test. I only get 50PSI at all speeds forward and reverse and neutral.

I'll go to the manual for next step.

Tks, Ed
