Hello all,

Have a strange one here...

My 96LS A/T has 90K miles on it. At about 65K I took it to the Chevy dealer and had them put it on the "tranny dialysis machine", to do the power flush/refresh of the A/T and fluid.

For about the past year the car will often - but not always - "bog" when shifting from Reverse to Drive - it may take several seconds before the 1st gear engages and then we go forward.

Sometimes if you give it a bit a throttle, this "pause or bog is then followed by a very hard sudden/jerky shift into forward (assuming the A/T is starting in 1st gear).

This behavior is then often - but not always - followed by being "stuck" in 1st gear, unless you blip the gas peddle once or twice to get it to upshift out of 1st and into 2nd.

Any ideas as to what this might be? A vac leak somewhere?
Is there some kind of kick-down "shift switch" to look for?

The TB was just cleaned, has a new air filter, and the fuel filter, plugs/coil packs are less than 9 months old.

Thanks in advance for the ideas folks!
Steve

Just noticed that I shoulda put this under the Transmission forum...

This sounds like it could jsut be low on fluid even. Did you check that first.

Thanks for the reply Rob, but there is no easy way to check the fluid level on the 2.4 A/T - the dipsticks at GM didn't put a dipstick on the tranny as far as I can tell.

Supposedly you crawl around underneath and check it like you would a differential.
