2001 Malibu auto trans surges at 30-60 mph almost as if you were riding the clutch??
 
I see where someone else is experiencing the same problem I am having at 127,000 miles. Does anyone know how to resolve??

May have better luck with this ?? in the Trans/Rear section.

More Info needed:
Light or heavy throttle?
Which gears? All?
Fluid condition, burnt/smelly,clear red?
Filter/fluid ever changed?

How does it behave if you take it out of OD?

I decided to replace the transmission fluid myself just recently, at 127,000 miles as I have complained about this problem each time I took it to a so called "reliable " transmission shop for a filter and fluid change.
It turns out that the three previous times they charged me for servicing,nothing was done because I found the original gasket on the pan.
What a buncha Crooks.
The fluid was burnt,but no filings. It was kinda dark and thick,but after changing the fluid with a recommended fluid for high mileage vehicles it is now shifting alot better. I saw the thread about using seafoam trans stuff and I just added 1/2 a bottle. I will let it circulate awhile and then change it again. I think it is pressure solenoid journals are clogging. It is fine when it is cold and then acts up after it gets hot.
I haven't yet tried leaving it in third. I will try that next. It does seem to happen only in third gear with light throttle.

Not siding w/the shops, but the pan gasket will sometimes get reused if it's in good condition. Burnt fluid (not just dark, I'm talking dark and smellyhttp://www.chevelles.com/forums/images/smilies/eek.gif) isn't something that a fluid and filter change will 'cure'- not for long, anyway.

Some Shops also install a hose down the Dipstick tube & suction the old fluid out. They can also flush the Trans using the Cooler lines while the Engines running. So maybe they didn't hose you like some shops have others .
A flush isn't usually a good idea as it can cause many problems.

Do you happen to have a Holley carb? If so, you might want to try a size larger on the primaries.
