I had my auto tranny serviced in my 01 SS camaro at the local chevy dealer and ever since then at slow speed less than 10 mph while still in 1st gear it seems to slip to neutral when I let off the gas and it will grab suddenly when I give it gas and RPMs catch up to that speed, anyone know whats going on here?

 

first, what was done to the car? knowing where they were at under the car probably will help others have an idea as to what it is.

 

The dealer did a complete flush and refill and new filter. The car has 43000 miles

 

When it does this, does the engine seem to rev freely, or does it just feel like its in a higher gear?

Is it possible they have have messed with the shift linkage at all?

 

Did you check the fluid level? Is this car driven hard?

 

The overrun assembly not holding (overrun clutches, overrun hub, overrun sprag) can cause this to happen.

 

the engine seems to rev freely. thamks for the response.
the car is not driven hard my wife drives it lik it has a 4 cylinder.
