OK, your previous post said "no R" so I thought it was completely dead.

I suspect you have an inoperative UD clutch. To get 1st gear, you need UD for the input, and either LR or the overrunning clutch (ORC) for the reaction. We know LR works (since Reverse is OK), so apparently UD is bad.

This could be a number of things (blown UD piston seal, defective UD solenoid, cut #1 check ball, broken UD shaft weld, broken rear sun gear, blown UD accumulator piston or seal, etc.). So we need to narrow things down. Any CEL or fault codes?
