Hello

[Gils]

I have Land CRuiser 80 with a 4.2 diesel 1HD-FT which received an automatic transmission A442 F; the car is former maula transmission. I encounter following "small" problem: when I put in drive the gear box acts like is in limp mode - the car moves only when a accelerate hard ( and it`s moving slowly). In L it goes normals , R also normal. Could anyone give me a hint or send me a good wiring diagram so I can measure the circuits ? Very helpfull would be to have also values for TCU connections and pinout.

many thanks from Romania.

Try locking the center differential and then see how it behaves.

Have you verified that the transmission control unit is properly connected?
If your transfer case has a viscous coupler HF2AV, that is what allowing for some movement.
