Drained & overfilled the gearbox yesterday, and am I glad I did. First, it's a rebuild, and the oil that came out looked like silver nail polish, from break-in I guess (hope). Second, because I used synth (Walmart house brand), the transmission shifts much more smoothly & easily. I didn't have as much trouble as I thought i would re-seating the shifter, but a rag or glove is essential for pushing down & holding it comfortably. Also, MAKE SURE that the transmission is in neutral before removing the shifter, or replacing it will be a pain in the rump. I had to find neutral with a screwdriver in order to finish. Oh-- and I gave it an additional quart.

I had the same issues.. when I bought my '92 it would get stuck in 5th gear.. I drain fluid.. and overfilled tranny with Mobil 1 Syn and have not had one problem with shifting since.. it is very smooth and has not got stuck in 5th gear once since

No magnet, just a plain pipe plug, but I can only imagine... I'll change it again in another 2 months just to be sure. Good thought on the warranty-- I'll ask the guy I bought it from (if applicable).

I would be willing to bet your silver oil is from aluminum worn off of the shifter forks. The most likely cause is excessive endplay of the mainshaft. I would check it again pretty soon as you will likely have trouble in the future. My 1990 had some silvery oil come out of it and the main shaft had over an 1/8 inch of movement. My .02.

Thanks for the tip (depressing as it is)-- I'll keep an eye on it.
