To check fluid cold: -park on flat surface -idle engine -remove dipstick and wipe clean -reinstall and then remove dipstick -reading should be on the cold mark To check fluid hot: -park on flat surface -idle engine -remove dipstick and wipe clean -reinstall and then remove dipstick -reading should be on the hot mark If checked cold and reading is over cold mark, it may be over filled.
If checked hot and reading is under hot mark, it's either not full or not up to operating temp so the reading will be incorrect. If it's not on the stick at all, it's low on fluid. Add 1 quart and recheck. I usually check it cold first, then if it's at the proper level, drive it awhile and get it hot, then recheck to verify it's on the hot mark.
VI is 6 also referred to as Dex 6. If your not sure or have an issue, take it to your nearest GM dealer and ask if someone can show you how to check it and make sure it's properly filled.
Dex 6 is not expensive and they should be able to show you in just a few minutes. I work at a dealer and show people stuff like that all the time. The fluid should be bright red with now metallic, shiny, rough or foreign particles and should not smell burnt, if it's burnt you will know because it really stinks when you take a whiff.
If the level is proper and the fluid is clean and the trans still doesn't feel right, there could be an internal problem with it OR the throttle valve TV cable requires readjustment. That can be addressed if needed at the proper time.
Best to start with fluid level and condition and proper cable setting before condemning a transmission as broken. Thank you guys for the reply I will check it this evening when I get home from work, hopefully its not a bigger issue, figure start small before getting all worried. No problem, sometimes that's all it is. You have the right attitude. You can always take pictures of the stick when you take the reading and then post them on here and we can tell you how it looks.
So I ended up checking the fluid with truck running, I had been driving for about an hour sitting in traffic so the truck was definitely warm. The fluid was only showing on one side of the dipstick and it was reading well over the full line. The other thing somewhat concerning to me was that there were bubbles on the stick. The fluid was red and did not smell burnt or anything.
