1998 Sunfire 105,000 miles. Bought used. Cured heating problems and a bunch of other stuff. The car was running fine. No hint of trouble. Gassed up, pulled out of the gas station, no hard acceleration. At 20mph there was a clank from the front and the wheels locked up. The engine stayed running. People tried to push the car, but it wouldn't roll regardless of shifter position. There is no sign of metal in the fluid, no discoloration or off smell. Floor shift. Dash indicator shows R when in park. Starts in Neutral but not Park. Revs in park or neutral. In any drive or reverse, the car strains to move in that direction but won't. Any ideas? Checks to make or tests to run before I go to the whole pull it out thing?

Time to pull it apart or get a new one... auto or manual trans, you didnt say.. and profile doesn't either.

He mentioned park, reverse, neutral, and drive. I`d say its an auto.

I agree tho, time for a new trans.
