Hello all,
I have been reading your forum for some time but I finally registered and have a question. I am working on a 4T65E trans. I'm thinking how to best word this to make it clear.
It seems to me that the endplay of the final drive is completely seperate from the endplay of the trans. (trans is less than .006 Final drive is .005 to .0025) I have a question and a possible answer. (guess) My service manual shows special tools to "push" the final drive forward then check the trans end play. The only thing I can think they are doing is making sure the final drive ring gear is pushed tight against the snap ring that retains it in the housing. None of the thrust from pushing on the final drive could be transmitted through the sun shaft and gears etc? They just want to be sure that when / if the final drive ring gear would ever move forward it won't run out of transmission end play.
I hope that is clear enough that you can understand my question. It's the best I can do right now. I am replacing the final drive and rebuilding the trans so I need to understand this as it is a little confusing why else they would push the final drive forward before checking trans end play. It seem the only thing that could move and affect the trans might be the final drive ring gear.
I'm posting here because it seems there are some very knowledgeable people that might help. So I say thanks to all in advance.
Mike
