Auto box oil leak

Hy guys 1991 gto na oil leak between AT & transfer box is there a GASKET there that just needs replacing and is it a doable job on drive way ? It definitely AT oil not transfer box oil I have checked,

Hi Billy
This is highly unlikely to be a gasket issue. Most likely an oil seal has gone. You can do this on your drive if you have some nice high axle stands and a good back.
If you aren’t in a rush, I have some videos in a couple of months which cover the entire transmission through to differential system. This will be for FWD, AWD, turbo and N/A, manual and automatic. Unfortunately, the automatic may be last so you may have to wait till later in the year.
