Anyone ever had your car running great, shifting fine, just stop pulling. No reverse, no forward gears, only park. Help, this thing is breaking me!

Sure did. The converter splines sheared off.

I hope its something simple like that. First time I have ever driven it, and bamm, another $1000...

When it happened to me, it was also the converter, bad sprag.

it was the pump in my th350

Filter sometimes falls off and does same thing. Depends on tranny type and fluid level.
