TC recommendation A999 (non lock up)
I have no more reverse but drive, even in neutral.
This is a transmission problem; I'm pretty sure the forward clutch is piled up.
I'm not saying that the TC is not also bad.
Your trans has 2 clutches and 2 bands and a sprag(one way roller clutch)
1)To get reverse your trans energizes both the
hi-clutch and the
L/R band.
2)To get manual Low, the trans energizes the
Forward-clutch and the
L/R band.
3)To get Low in "Drive" position, only the
Forward-clutch is energized which then gets first gear thru the
sprag.
4)If the trans drives in Neutral, then the
Forward-clutch and
sprag are working. But the
forward-clutch is NOT supposed to be engaged in Neutral.
5) in neutral all clutches and all bands are disengaged and all oil flow to these circuits is dumped into the pan.
6)If you have no reverse, then one or both, of either the
hi-clutch or the
L/R band is not working.
OR the
forward clutch is jammed up, which then selects two gears at once, and the car cannot move.
7) From #4 we know your
forward clutch is engaged,when it is not supposed to be.
The only way this can happen is if the forward clutches are all welded together.
IMHO; EITHER the Forward-clutch or the hi-clutch started slipping during the fun-time, and you probably finished the Forward clutch off, doing the brake stall test
. So the Hi-clutch MAY also be bad .In any case;
IMO the trans has to be opened up
