Transmission problem
2000 Chevy Blazer 6 cyl Four Wheel Drive Automatic 140k miles
I was driving aproximately 35mph and had to brake hard. While still moving forward, the gearshift got bumped from forward to reverse. "Not a good sound" (sort of a "POP" came from the transmission. Now I have no reverse and the transmission shifts at around 35mph from 1st to 2nd. Can you advise on the components that are "most likely" to have been damaged? I plan on doing the work myself, but I would like to get an idea if it's worth it.
