Morning everybody,

So, I've just had a full engine rebuild on my 230te and it runs beautifully and for the first time doesn't leak. But....

The gear changes on the transmission are now all over the place. It'll still change up but only when it gets to 3000 revs. Or alternatively when i lift off the accelerator momentarily.

Heard a lot about the vacuum modulator and wondering if it's that. Any ideas.

Thanks.

Most probably vacuum related.

Have you checked all the vacuum pipes are correctly fitted back to the engine?
 
I haven't checked that yet. It did cross my mind if something like that was the case. Thanks.

As above, check kick down switch, if vac is missing that would result in a harsh gearchange. Check the throttle cable and modulating cable are adjusted correctly.
 
Definitely vacuum pipes incorrectly connected. The shift quality replies on good pressure.

Also I would check the ATF level incase any was lost.
