Use the GM oil, I know other people will recommend other brands but the GM product works very well.

I like Royal Purple, but the stiffness could easily be in the shifter, which you can access from inside the car.

Well......it's got the GM oil in there now and it only has 52,000 miles......I figured another brand might might make it shift better......then again it could shift worse with another brand that's why I was asking if anyone has tried another oil.

when you say it could be the shifter, what do you mean?

I have only 7800 on mine but because of the age I went ahead and changed. The mileage is one part of it the age of the fluid is also an important factor.

Dunno what is applicable to Kappas...but changing the trans fluid on my Camaro did nothing for shifter "feel".

Changing the clutch DID make a difference. So did the Hurst short-throw shifter kit.

I'd start by checking the linkage and making sure everything is happy. (Not worn, properly lubricated, etc.) Then, I'd make sure the clutch is disengaging properly. (the issue on my Camaro. It wasn't. (isn't))

I did change the fluid of my TR6060 to RP Syncromesh, but that had to do with expected temps/wear/abuse from racing, not seeking a better shift "feel". That being said, I changed my clutch last spring and the trans fluid was still purple...after two years of use and abuse. Bottom line, unless the manual says change and/or you see trans temps over 180*F I don't think anyone needs to worry about trans fluid in a manual...unless you grenade it, but then you've got bigger issues...
