slow accelerator/ no kickdown.. i think gearbox! sorted!!!!

[ruffryder]

have a 325i auto and it wont go as it used to.... the story is the car started to run rough and the fuel pump was making a loud buzzing noise, carried on driving it then one morning the car started then died... would not start up.... i changed the pump (2nd hand one) and the car started, it has no reving problem and idles fine. when i put it in drive and accelerate it moves off very slow as if it dragging something..... i have changed the fuel filter no difference..... also when driving, it does not do kickdown.... any ideas????

i think i know the answer now just need a opnion... i took the car for a drive and it dont seem like its changing gear, it seems it selects 3rd gear or something, i've tried 1st gear and still the same... gone through all gears manually (1,2,3,d) sports mode..ect. nothing... its fine in reverse... any help would be great... thinking about changing gearbox oil????

Check the quality of the oil it should be red not brown. If you gone change the oil change the gearbox filter aswell. is worth a try alot cheaper then a gearbox

The gearbox is set to select third in case somthing is wrong, as i said make sure the oil is red and check the level aswell
