hi all i have just aquired a 1999 v reg 2.3 auto galaxy with a gearbox fault , it wont change up from 2nd gear , i have 1st, 2nd and reverse and thats it if you drive car the autobox gets very hot to the touch. my friend told me he has changed the gearbox to a newer tiptronic box as the origninal was slipping its had new torque converter and he changed ecu then this fault developed when it was all put back together he had many headaches with this and gave up and passed the car on to me he thought that maybe it needs recoding due to new ecu and box , but i just wondering if it could be fluid levels or something similar any help please
