VY Equivalent Statesman Issue. (WK) - Vibration?

[VLSabo]

Hey guys,

I recently got my auto transmission done, got a old one out, and new one in. this is in a WK Statesman (VY Equivalent).

Anyway, I took it home, on the way home I felt vibrations (increasing as you accelerate from 20-25). But not when you brake. It only vibrates at that certain speed, from what ive noticed anyway. Runs fine at higher speeds etc.

I first assumed they put on the tailshaft to the diff wrong (as it has to be balanced?), I went back to them and they told me they never took it off.

Another mate told me that it could be my tyres, from feathering, but why would it only do it at 20-25km p/h?).

Anyone have any suggestions, would wheelbearings have anything to do with it etc?

I reckon you got an early model Trans , did they put the same Trans back in it or an exchange one??? Some Trans had different rear housings. There may not be enough tailshaft sliding engagement into the rear of the Trans
