Hi, my citroen saxo 1.4 auto, mb3 gearbox, shifts harshly at light throttle going from 2 to 3.
It's as if the line pressure is too high, but I cannot find any info on it.
Thanks,
Fred.

Hi you seem to know a bit about gearbox,s?
First thing to check on these wonderful mb3 gearbox,s is take the pipe of the vacuum modulator and see if there is any oil in it,if there is you need a new modulator.If you replace it count the amount of turns to get the old one out then turn the new one the same when you put it in.
Also what,s the oil condition like?
As the valve body,s get stuck very easy on these.
Quite a simple job to remove the valve body and go through it you would need new gaskets and a filter but the main concern would be something is braking up and creating swarf.
Hope this helps if you need and more help e-mail me at
