My Tranny is acting up. When I get-in and start the car and get ready to back-out of the driveway ... it SEEMS like there's a momentary hesitation before the tranny starts to move the car.

Back-out stop and shift into drive.
There is an audible "Clunk" and I can definitely FEEL the car shift into Drive.
As I proceed down the road ... in the city ... going slow ... I FEEL the shifts as the Monte drives along with me on our merry way.

The Harshness is NEW.
I want to get whatever needs to get done ... done before this gets out of hand.

Who knows what this issue is and whats causing it?

My CEL is on for a O-2 Sensor I haven't got fixed yet.

As always ... thanks in advance for helping me out.

Get the codes re-read- I bet there's one for the transmission pressure control solenoid.

This is a common failure on GM front wheel drives with the 4T65E.

When the solenoid fails, the transmission commands maximum line pressure for all shifts, meaning it shifts HARD. If you get the solenoid replaced ASAP nothing else will be damaged. Make sure you take it to a reputable shop- many will tell you you need a whole new transmission, when in reality your problems can be fixed by a $30 part.

Good luck. Let us know what happens.

 

Yeah sounds like how mine was acting when the PCS went out. Unfortunately my trans was toast and I had to have mine rebuilt.

 

Great, thanks for the heads up.
Mine is doing the same thing, exactly as OP described it.
appreciated.

 

yeah mine is startin to hesitate to shift as well. thanks for the info!

 

I've had the PCS code for years now lol

But yeah, you may want to see if getting your O2 sensor changed will help.

Go ahead and start saving for a new transmission though...

 

^ very unfortunate lol there.
