P38 stuck in low gear

I talked my friend into buying a $1,000 2001 Range Rover with a bad 4hp24 auto transmission. We rebuilt the transmission and took the transfer case apart, but it looked good so we left it alone. A job offer came and I had to move states, but he was able to get it back together with another friends help (even though he has never worked on cars before) and drove it recently. Everything worked great except it seems like it's stuck in low gear (4 gear, 50mph at 5k rpm). It seems to shift through gears just fine though. He does have the shifter on the high side gate.
He was able to remove the gear selector motor off the TC and was able to rotate the shaft. He said when he rotated the shaft he was able to put it into neutral because the truck started to roll a little. He rotated it both fully counterclockwise and test drove it and fully clockwise and test drove it but in both cases it still seems to be in low. Is there a specific location the shaft needs to be in to be in high? I would expect load to be fully counterclockwise and high to be fully clockwise but maybe not.

Does it go into neutral with a fuse in F11?

I can't remember which way round it is but you're right, it rotates fully one way or the other on the triangular shaft to shift from high to low or vice-versa.

The pin-outs with the expected voltages on the plug pins are in RAVE.

I don't think it's an electrical issue because he's removed the selector motor and is manually moving the shaft. I think he put it back together incorrectly or is rotating too far. Just not sure.

Do a search on here as there was a similar thread.
The TB box had be incorrectly assembled.

It’s a bit strange that it can be turned manually to neutral but not to hi.
Seems strange that CW &CCW give the same results. But he can find neutral.

Also if it still (electronically) thinks it’s in low then the engine and gearbox have different maps for low.

Put it in neutral mechanically. Put fuse 11 in, this should shift the change motor to neutral.
Put everything back together and remove fuse 11.

If it working mechanically then maybe it’s the switch not showing it has moved

That’s all I can suggest.

Yeah sounds like the motor and shaft where not clocked correctly.

It could also be that the internal spring mechanism is not assembled correctly. As you rotate the shaft it builds of tesion on a spring inside the box until there is enough tension to engage the teeth.

Just as an add, I assume the dash shows P,R,N,D when the stick is in the correct position.
It needs to show N for it to switch from low to hi

TB when assembled will be in the low position and the gearlever has to be moved to and see N for it to move to Hi (if I remember correctly)
So it could also be the adjusment of the XY switch as this was obviously off for the rebuild.

The dash does show the correct P, R, N, D, 3, 2 , 1. We adjusted the shift cable until the lights and dash showed up correctly.

Seedeal is the sucker, I mean friend, I talked into buying a Rover with a bad tranny.

Charlie, please explain what you did that got the tranny stuck in reverse.
