landrover..fault forward gears..Transmission Speed Sensor

Customer Question

I have a 2001 Landrover Discovery. The fault readings are P0722 and P1590. I have no forward gears, and I have replaced the Transmission Speed Sensor with no results. Where should I go from here?

Hello, Sorry but if it has Reverse, your issue is internal & the transmission needs rebuilt........Just to the Facts......Sorry again I hate to give bad news......Thanks Joey

I cannot accept your answer. I am also a mechanic, and I have the equipment to problem solve system failures. There is no indication that the transmission needs to be replaced. There was very little residue in the pan when I removed it and the oil was normal. The two fault codes that I sent were the only problems that came up when I went through the system. Thank you for your reply. Dave
