Hopefully someone can explain whats going on with my trans...
After an hour of driving.. the car starts to shift 3times harder as usual. It seems to be getting worse. If the trans is going bad I will more than likely be trading it in. Thanks!

How many miles? Any codes? Do you keep up with the fluid changing at all? Is the fluid burnt spelling and brown?

118,400. Fluids were changed at 68k, and it is still pinkish, but I did see a little bit of black debris.

Black debris sure sounds like clutch material. Some of these more knowledgeable guys might be able to help you out further. Sorry to hear about the troubles.

Dexron best as far as tranny fluid but gotta get at dealership then all u need is the filter and your set.

From what i've read DexVI is what everyone uses but I also read on gpf.net that owner of tripleedgeperformance.com recommended Dex III but no response in regards to why.

Edit: found it http://www.grandprixforums.net/dex-vi-f ... 39123.html

I threw in DexVI and a new filter this morning, seems to be shifting fine. If there is still a problem, it will definitely show up in the next 2 days. Good thing I didn't jump on the dealer train lol.
Thanks,
Kray

^ Good to hear. You gotta realize the tranny do eventually go out especially when modded. You just gotta put the money toward it for when it happens or contact ed morad and get a used replacement.

Hey i got a question. Can dex. 3 be mixed with dex. 6? I dont know what was in my tranny before, but i have been using dex 3 now, and when i looked today to see what lvl the tranny fluid was at it was at the bottom line :S Its not lookin 2 good for my tranny it was slipping a bit today before i checked the level

-- Mon Dec 06, 2010 11:11 pm --

Well, i just drove it 250k after adding the fluid and its workin much better. I am certainly going to get a filter and change the fluid though in the next few weeks.

_________________

I didn't flush mine, just changed it. So obviously they are mixed! but the answer to your question i'm not sure... I know they are compatible, so it should be fine.

p.s Another question--Would off the shelf tune made in the summer effect the driving in the winter? (Cause the calibrations to get confused?)

Apparently 04 Comp G's transmissions like to fail. I've not been too hard on my car in the time I've owned it. I'm assuming owner before me beat on it quite a bit, however I think these transmissions just suck.

My transmission hit the end a few days ago, it sounds like yours krayman could be on its way out but with warning. Mine gave no warning.

_________________

I hope not! I have a ZZP pcm on its way hopefully be here next week, and it gets pretty cold up here in canada (-50C) so it better not!



I kind of have been expecting mine to die for a while now, after all it has 204k on it and the owner(s) before me probably drove it like it should be driven Oh well i got a great price on the car if i have to do a bit of transmission work soon i won't be complainin.

_________________

Lol, 204k, that tranny has served a life time for a car. My cars tran died out @ 84k.

_________________

Ha, yeah it sure has i think ive put about 20k on it myself definately gonna change the filter and tranny fluid out completely pretty quick here and see if i can get a bit more out of it.
