Greetings all,

Am hoping someone here can help with a few questions I have. I'm beginning an overhaul of a 4T60-E transaxle from a '93. I rebuilt transmissions for a living until 1981, but aside from a few mid '60s Riviera'* & '70s Eldorados, this is the first FWD tranny that I've touched in over 2 decades, and I've never touched this particular model before.

I have the ATSG manual and the video too, but can't find any reference regarding how to remove the external drive components (output shafts?) that the inner CV joints mate with. I don't even know what they're called! (PTO'*?) LOL. I started to disassemble the thing, thinking that maybe it had some internal C-clips or something, but from what I'm seeing, I have to get these external pieces off of the final drive(*)/output shafts, etc, or I won't be able to dissemble it much further. Ironically, these are absent from both the
manual *and* the video as well, so I can't find any reference there either. Apparently the assumption is that the technician already knows how to remove these before overhauling the tranny. (I wish!) Can someone here please shed some light on this? Any information is greatly appreciated. Thanks! (again!)

FYI, here are a few pix of the components I'm speaking of:

There is a retainer on the shaft that goes into the transmission. Get a pry bar behind the inner cv joint (between the joint and the transmission case) and try to give it a good quick "pop" and it should come right out. It may be a bit harder to do with it out of the car. This is a thread that explains it.

Had the same problem on my wife'* 92. I pried and pushed and pulled for about 30 minutes and then my father-in-law grabs a chain and wraps it around the "hub" and clamped some vice grips to connect the chain and gave it a real hard, quick yank and off it came. I think he said they call that a "pull hammer".

These should come out with a slight pry after pushing in.. it'* a pop it out motion. However first you put it in to get pressure off the retainer.

Wow, you folks are EXTREMELY helpful. Thank you very, very much. Even on the bench, a sharp tap with a 4lb sledge and a long prybar did the trick with ease.







Seeing the CV-Joints in pieces made me wonder something. For those that have done these FWD R&R'*, would you recommend re-assembling the axle shafts with CV-Joints in place (booted & banded) and install them as assemblies after the trans is back in the car, or is it wiser to install the inner tripots (see, you folks taught me a new word ) to the trans before putting it back in the car?

Thanks again!

Assemble the CV'* them install the assembly to the car, Makes the drivetrain smaller and easier to fanagle in. Plus it keeps the CV'* cleaner.

Not to mention being a lot easier to work on off the car. Unless you prefer to rebuild the CV joints, you may want to check into the cost of replacement axles. Often the cost of the entire unit is quite competitive to rebuilding, especially when you factor in the time and effort.
