A couple months ago I had to replace the manual transmission, after a catastrophic differential failure. A local shop had a spare transmission case, assembled all the right gears, and the rebuilt transmission works great and shifts better than the old one.
At the same time, I had to replace the VR6 clutch plate because the old one was contaminated with gearbox oil. The G60 flywheel was cleaned up and reused.
Very soon after my Golf was back on the road, I noticed a vibration starting around 3700-3800 rpm. Previously I was able to rev smoothly to about 5000 rpm. So I was understandably concerned.
I went back to the local shop, they put the Golf up on the hoist, and found that the dogbone engine mount was in poor condition. They replaced it with an after-market or performance dogbone and the results were horrible. There was so much engine vibration being transmitted to the chassis, that it was unpleasant to drive. ASAP I went back and the shop installed an OE dogbone, and the constant vibration went away. But I still have the vibration at 3700 rpm.
I am not sure if this is related, but there's also a little bit of a vibration at around 1900 rpm in high gear -- not exactly lugging, but just above the point where lugging could take place.
I am wondering if I need to replace the other engine mounts, or the transmission mounts, or if the problem could be from another cause. Any suggestions? My Golf is running very well except for this single problem.
