Passenger side cv gone bad on my 1995 legacy auto trans. Pulled out of my parts car a 97 manual trans legacy. Are these interchangable. The 97 looks larger, shaft diameter thicker and joints look beefier. Are these interchangeable?. Also when I removed cv axle from the working 1995 the splined shaft came out of tranny followed by tranny fluid. Doesn't appear damaged so I just pushed it back in. But before I proceed wanted to verify if I have a bigger problem here or anything special needs to be done to avoid a bigger problem.

It will fit, but it will have a vibration in at stop in gear. The Manuel trans has a slightly different DOJ cup than the auto IIRC.

Just read the other half of your post. The spline shaft that attaches the C.V. to the transmission should not be coming out. If it just fell out when you pulled the axle out it will probably still work, but i would say it does need to be taken care of sooner than later.  the cv axel may not be cuplrit eaither is their any damage to the boot or any play?

Just a heads up. Trans fluid should NOT come out of the 4eat front diff. If trans fluid (red in color) came out, you have an internal seal bad. If gear oil (black) came out you're in good shape

Oil that came out is dark brown. Gear oil? How to check? Also cv is definitely shot boot torn, tons of play.

Dark brown would be gear oil which is what you should be seeing. And if the CV is shot for sure and the car was still running like that it will probably still function once everything is back in place. I wouldn't venture far enough to say its neccisarilly safe that way though.

Was the circlip still on the end of the stub when it popped out? If the circlip is gone you need to get a new circlip.

 

Larger axle is probably aftermarket. They always have larger joints. Not always a good thing either. It'll fit and work, but may cause a vibration, may also start clicking soon.

 

Front diff uses 80w-90 gear oil. Dipstick is on the passenger side of the trans.

Is a circlip all that holds those in? Cause I've pulled the Axel out the doj cup before when trying to remove a stubborn Axel and those stubs are super solid.

Yep, just a circlip. And yeah they're tough to pop out because you're not supposed to remove the stub to remove the axle.

 

On manual trans there's actually a C-clip/snap ring on the inside so the stubs can't be pulled out.

Clip still on shaft.

I can't find dipstick for gear oil. I'm looking on passenger side of tranny but can't find.

Output shaft won't go all the way in. Splines engage but only about 1/4in. I'm sure c clip is preventing sliding on the rest of the way. Do I just drive it on?

Insert the stub with the opening of the circlip pointing down. It ask helps to coat the clip with grease to hold it somewhat centered. Tap it with a hammer a few times to get it to seat.
