I reccomend adding lucas engine additive along with you oem fluid. it says on the bottle for use in light duty manual transmissions, I tried it once in mine and it elliminated any hard shifting I was having and it's running better than ever. Add it to your oil too it's good stuff...

You can also try a quick lube if you don't want to go to the dealer for the fluid. I know jiffy lube carries what they call GL-4 which is made by pennzoil and conforms to factory specs. I've had it in my tranny for over a year with no problems.
