Update. The car seems to work in reverse fine now. I drove it around and got a P0742 code and P1811. Talk about hard shifts! Here's the problem though. 2nd gear seems like it's missing. I temporarily disconnected the lockup wire at the harness plug so the Converter clutch stays off. Drives ok, but 2nd is a no go. It shifts from 1st to 3rd. I believe something may have broke during the hard shifts with the converter locked up. Any input?
