Nm trans issue

[To-tacos]

Hey all, chasing a no drive problem with my automatic 3.5.
The car has had ongoing transfer issues but i drove the car home last week and noticed it wouldnt go into high gear (5th?) But spent the weeking working on the transfer (swapping solenoids and free wheeling actuator) to no luck.
Started the car monday and it had no drive or reverse what so ever and when selecting "park" it would grind like the wheels are still spinning.
Scan tool shows car is selecting all options (p,r,n,d manual up and down) and will drop rpm when selecting drive gears.
Not alot of experience with autos so diagnostics are fairly basic. Would it be as simple as torque converter or is it most likely rebuilt time?

Thanks
Ben

I hope for the sake of your bank balance I'm wrong but things like that happen when the gear set falls to pieces.
The more you try and drive it the more damage you will do.
Mine did similar at 375K and was a complete rebuild. Not much change out of $8000 by the time it was removed, rebuilt and refitted.
When the pan was removed bits fell out so that was a good indication a rebuild was necessary.
