Hi everyone,
Tonight I was driving my 2008 Silverado(42,000 miles) when all of the sudden I heard and felt a large clunk under the truck. I thought I had hit something at first. I immediately was unable to acclerate in Drive. The RPM's would increase but it would not go. I was able to put it in first gear and drive home about 1/8 mile. The tranny temp or engine temp did not increase. All fluid levels were normal. It will still go in reverse. Please tell me what you think.
Thanks...

still sounds like a tranny issue to me

Have you done anything that would lock and unlock the G80 recently? I have heard of them just blowing up....

Have you contacted your local dealership regarding this concern? It is difficult to diagnose an issue from here, but I would like to look into this further for you. In order to do some more research, I will need the VIN for the vehicle as well as the current mileage. I hope to hear from you soon. Thank you in advance.
