2008 Cobalt Automatic Transmission Issue

[petedaddy]

Hello everyone and thanks in advance for any help on this issue.

I am trying to troubleshoot potential transmission problems on my sister's 2008 Cobalt.

The problem is that the car is going into high RPM's (around 4,000) before shifting into 4th gear. The car shifts perfectly in lower gears, and the problem is only when shifting into 4th gear.

Does anyone have any ideas on what may be causing this?

Thanks!

Pete

that would be a better site to ask. this one is mostly dead and there's a lot of information that the members know there

Hi Pete,

Sorry I am unable to diagnose your issue you're having with your sister's vehicle. You would need to speak with a Certified Mechanic/Technician about the issue you are having.

The vehicle would have to be scanned with a GM tech 2. This issues could be a wide variety of things. possibilities may include an engine performance issue, tps issue, tcm issue, trans clutch pack issue, wiring issues.
