I am loosing trans fluid but see no leaks under car. I now understand that it may be a cv seal? I found these cheap enough and comments indicate it is a easy replacement. Does anybody know where I could find directions on how to replace this seal? ---

My answer is in reply to your first post and the transmission has 2 halfshaft seals, not one. You need to consider other possibilities too as a leaking halfshaft seal is very obvious. ---

Thanks OK, will do. Thanks once again. I think I need to invest in a chiltons manual for this thing. LOL This is the wife’s car, I have a old 92 GMC Sierra v6 1400 and I can fix just about anything on it, nothing fancy at all, just a good solid farm truck. Her’s can drive me nuts. Had to remove the alternator to replace the heater inlet screw in five dollar part. Where is the halfshaft seal located, I assume the cv seal is where the axle joing the transmission. I am still trying to find some diagrams, shop manuals or pictures online. No success yet. Thanks again for the help, George ---

To find the halfshaft seal, get the car raised and supported safely; slide under and follow the shaft from the left front wheel to the inner CV joint; the cup of that joint will be stuck into the transmission; and the seal will be around the shaft that enters the transmission. Usually if the seal is leaking there will be a dirt/oil trail downward. Do the same for the right half shaft.
