Inspection of a 904 torqueflite

I didn't say it wouldn't move if you pushed in on it. I can't comprehend how you can't understand that the driveshaft can never push the output shaft forward or it will destroy the transmission. The yoke must never bottom out on the output shaft; that's why there's plenty of room for it to slip in and out. You're a more trusting soul than me if you believe that that's a low gear set, the seller says it's 904 and purposely (I think) has left out pics of the front of the sun gear. In the seller's defense tho, I don't remember the ad stating that it was a low gear set. I could be wrong about that; I just don't want to bother looking at the ad again. I will wait for the op to post his progress before I post again. Maybe someone else can chime in on those two issues for you.
