hi guys new to the forum but really need some expert advice,im a mechanic and have been for 25 years,,but ive always stayed away from automatics,,,basically i have 2 voyagers,1 ive had for 2 years no probs at all,,,and 1 i bought off an old man who had enougth of spending on it and sold it as spares or repairs,,reason i bought it was LPG,i purchased it as having no reverse,,it selected l d and 3 but would not select reverse,,,and as i tried to drive it it would drive,then as it went to shift it would lose drive and throw engine light,,turn it off,restart and select gear and drive till change,then no drive again,,i then towed it 166 miles home.put tester on it next day and got codes p0700 transmission control system malfunction,,p0732 gear 2 incorrect gear ratio,,and p0132 02 sensor circuit high voltage bank 1 sensor 1,,,i proceded to check the oil wich was fine and right colour and unburnt,,i then decided to try input speed sensor out of my other voyager,,but no good still had same problem,,,so now im stuck,,ive read loads of stuff and cant really find the answer,,,going to check all cables and earth straps today,,,,,,as i dealt with the old mans nephew,,who knew nothing regarding the car i didnt get any ideas of what happened to it when it went wrong,,it pulls great with plenty of grip in d l and 3rd until the change,,,as for reverse it feels like its not engaging at all,,,thankyou to anyone who takes time to read this and can help me,,,thanks,,,,,3.3 v6 1999,,,
