Ea II shuddering problem
My girlfriend recently purchased a series II EA falcon (4 speed auto and 3.9 CPI) and it has a strange problem. When you are driving along at about 80 kph and the revs slip below 1500 the car starts to shudder. It feels like it may be coming from the auto. I have taken it to the transmission place and he replaced a rear bush. This has still not fixed the problem. One suggestion was the tailshaft however it only seems to do it in 4th gear and not third gear. The shuddering stops once you start going about 100 kph.
Can anyone shed any light on what it could be?? It would be much appreciated as the problem is driving me mad.
Now the proud owner of an AU xr8 220... OHHH YeAh
