02 Grand Prix Transmission Questions...

Hey all, I'm planning on doing a pan drop and filter change on my 2002 Grand Prix SE (3.1L) with 165,000 miles and had a few questions.

First, if I'm only going to do a pan drop (only replacing half the fluid) should I stick with Dex 3 or should I put Dex 6 in? I have no idea the past maintenance on the transmission so its possible it might already have 6 in it. Right now the fluid isn't really brown but its not a clean red either.

Second, I was considering getting a shift kit (possibly ZZP?) because my car seems to shift funny sometimes. Like it seems like the shift takes longer than it should and it will sometimes sound like it just dosent want to go into gear (its not like a slip-bang. It just takes a little longer than usual to shift). Would a shift kit help with this problem? Or would it at least help my transmission out a little?

Thanks in advance! (:
 


Use either fluid. Your choice

On the shift kit. It really depends on what is causing the issue. Since we can't tell that.. not sure it will or won't help out.
 
What would be the advantage of switching to Dex 6?
Well I brought my car in to Valvoline to have the oil changed (I usually just do it myself but I havent been felling the best lately) and he told me the previous owner always brought this car there for oil changes and such, and told me that he had the tranny flushed about 50,000 miles ago. I dont really feel like paying the $130 to have them flush it, would it really benifit me more than just a pan drop?
 
Flush is a 100% fluid change, sometimes they change the filter after..sometimes they don't.

Pan drop is 50% fluid change with a filter. And if you are shift kitting..this is the time to do it.

On the pro's and con's of dex6 .. please search. I've never used it myself and am unsure of the actual results.
 
I would go with Dexron VI. It is a much better fluid than Dexron III. And it will mix with the fluid in your tranny just fine. No issues there.

When I changed to Dexron VI, I noticed lower tranny temps and slightly better fuel mileage. I am anal about recording my mileage. So I noticed it gained .5-1mpg.
