The RP made the tranny grind worse than before once it heats up.

 

Gear oil is the most nasy smelling **** ever! I put 80w/90 in my trans in my '86 gxl. Still get ruff ***** into 2nd and third intermintly (sp), not sure if im just in need of a tranny rebuild/new trans b/c of synchro wear, but when I changed the fluid there was no gold flakes in it at all, which is a huge sign of synchro wear (since there brass). I want to try some Redline MT-90 synthetic, maybe even that shock stuff that I hear people bragging about made by them. Its just so damn spendy though, and if it stays the same....
