wrong Automatic Transmission Fluid or to much?
I got 12 quarts of ATF and bought it to jiffy lube they said they put all 12 quarts in. (I doubt that for some odd reason) I noticed while running through the gears or at high rpms it seems to slip now. It will still pop into gear though but if im at 5,000rpms in first thats when i put it into second and it might bounce off the limiter before getting into gear.
Car had 87k miles on it and It is safe to assume it had the stock ATF in it.
This is what I had them put in it.

How did you determine that 12 quarts was required?

Maybe they put power steering fluid in it instead (kept your ATF). Some people think power steering fluid and automatic transmission fluid is all the same stuff anyway...

They said they used 12 quarts flushing the system out and refilling it.
I don't know if it is slipping or if i'm not use to it being so smooth.

You had them flush it....?
Sounds like you need to get the facts together.[/QUOTE]They changed the filter and they flushed the system and put a new seal on the pan. Thats what I got out of it.

new GM recommendation....for Auto transmissions
I put the Valvoline DEXRON VI in my car...did it myself. The car shifts much better and handles High Temps better. Since Dexron III is no longer liscensed I don't really trust DEX III. But that doesn't mean what you put in was wrong. I just like to use what meets the newer/better standard. DEXRON VI is for Automatics only...My car has 180000 + miles.

I am in the same situation as you are...my car has 85K and from what I could find out about the car, the original atf is still in it. I have made calls to LG Motorsports and Corvettes of Dallas asking for recomendations about having the system flushed or just dropping the pan, changing filters and refilling. After tons of reading and the conversations with those guys, everthing points towards not flushing the system. I hope you didn't hurt anything! Keep us posted on how the tranny is doing... Good Luck!!

I dropped the pan on mine...changed Pan gasket, filter, filter seal (tough)...Used a rented tool (Blind Hole puller) from Autozone to get that out. Because the car was just on ramps I had to buy a large bolt and washer to use for the slide on the blind hole puller but I finally got it out. Some come right out on my research....But if you have one that doesn't, get ready for a fight. I drained the fluid dropped the pan replaced the filter refilled. I did it again about a month later....refilled. I intend to do it about once a year now....No problems. Used the new DEXRON VI....180000 + miles before this was done......DEXRON VI made a big change in smoothness temps etc. You had better do the research though...I seem to remember that I had to have the car running and at a specific temperature when refilling. I followed the procedure in the Shop manual

Why oh why would you take your vette to Jiffy Lub? Seriously, don't do that! I wouldn't take my lawnmower to Jiffy Lub based on the experience I've had with them. Please keep in mind that the people working there are not certified mechanics or even close to being mechanically inclined.
Thank goodness that you at least brought your own transmission fluid. Who knows what they would've put in.

I prefer to get it from those who have experienced it first hand, like the good folks on this site.

I didn't think it was possible to overfill the transmission. The instructions are to keep pouring it in until it overflows the fill hole. It is possible they didn't fill it enough which can present as the car having to rev higher and, in some cases, shift harder.
I don't remember the exact procedure but I thought you had to actually move the gear shift into and out of reverse also to make sure it gets everywhere.

I never proclaimed to know more than GM...if I was being advised by a tech at the plant in Bowling Green, I wud follow his recomendation; however, the service manual is 6 years old. By your reasoning, the manual says to use DEX 3 so I guess you would that instead of DEX VI because GM knows best and built the car, right? It nice to know there are still people out there like you that will believe anything they read is still current.. I prefer to get it from those who have experienced it first hand, like the good folks on this site.
