I'm experiencing some problems with my 2.8 diesel car gearbox. After driving someway it suddenly starts to jump out of the gears, the engine light comes on and the speedometer either shoots backwards and forwards or stays completely stuck in 0. We then feel we have to travel at less than 30mph to correspond with the gear it feels to be in.

When the cars stationary and stick it on reverse it won't move unless full throttle is given. The car feels as though it can't move out of 1st gear. And when the car starts moving it's a bit like shaking. The same in reverse.

When I get the car going it's changing the gears smoothly. Till it's jumps out of the gear.

I have read the code and it's speed sensor faulty. I have ordered both, input and output sensors. But I don't think it's will fix the problem with the car sticking in to the reverse or first gear.

The shacking when moving and slow moving from stop could be related to the torque converter and/or fluid, the other faults could be related to it also, check the fluid first, if is not clean is a sign.

 

Hope it helps.

I been to few garages now and they are saying that it could be a torque converter or a planetary gear set. Either way it's not cheap fix. The Oil probably could do with a change, but I don't believe in simple fix, don't think that the oil change will fix this.

A sign of bad torque converter is dirt in the fluid, by taking some out (the dirt should sit at the bottom) you can tell 50/50 if is the torque, unfortunately is not an easy fix specially on the automatic gearboxes...

What I am trying to say is, if something is wrong generally with a gearbox it can be spot it in the oil, there is friction and spinning inside there and most of the faults would cause debris into oil...or sounds that shouldn't come from the gearbox. You can try, if for some reason is low on oil it (check for leaks around the gearbox) could be the fix for it, but if when the oil is removed is not clean investigate further. Edited by mikebh8
