4L60E leaking

[VortecJeep]

Have a '97 4L60E in my YJ. It is leaking, and I believe it is leaking at the shaft that goes into the the side of the tranny to change gears. Does anybody know if there is a seal there that can easily be changed? Anybody got any drawings or manuals on the 4L60E?

There is a seal. You will have to take the inner and outer linkage, and the manual shaft out to replace it.

Will I have to drop the pan, or will I be able to just pull it out?

IIRC, the pan and the valvebody most likely? Might not need the VB, but certainly the pan.

Actually Im pretty sure the VB has to come out....

You can remove just the shaft and replace the seal, but you'll most likely bust your knuckles on the valvebody. It may be easier to just drop the valve body and remove the linkage all together.

I've only dropped the pan once before; that was a couple years ago before I had the tranny rebuilt. Is the valvebody the part that looks like a rat-maze with ball bearings in it?

 

[Ron]

yes....BE CAREFUL

Yes and there are checkballs on top of the valvebody that fall out(5 or 6?) when you take the valve body out. Also there are 3 different length bolts and installing the wrong ones in the wrong place will LOCK the gear train.
The leaking shaft seal is a problem on the 4l60e/4l80e, so much that this http://buy1.snapon.com/catalog/item...&group_ID=1617&store=snapon-store&dir=catalog
tool is made to change it without even draining the fluid. (i have one)

Thanks, as windy as it is here today, I won't be doing anything but watching football with two eyes closed!
