Hello all (and Colin),
I'm trying to get the inside of my '75 camper as noise-free as possible (Colin's suggestion last year to go with the stock muffler over my Vintage Speed one helped s lot) but the other noise I have is a whine from the tranny, in all gears, that might be resonating into the cabin from the shift rod.
All of my shift rod bushings are new/intact, as is my coupler. I was the one who installed the engine and transmission and I didn't follow much of a process for fine tuning the position after it was installed on the engine/tranny mounts.
I thought I had seen a thread on IAC where Colin suggested loosening the front tranny attachment point and moving the tranny front up or down slightly to relieve stress on the shift rod, but now I can't find that thread :-/ In general, could any small adjustment of the mustache bar end mounts, of the tranny mounts, eliminate whine?
Thanks!
- Doug

Do you get this noise or reverberation at idle? There are two 17mm NUTS not bolts that hold the nose cone mount to the transaxle. Usually, you need to remove the big plate with the 17mm BOLTS going up into the torsion tube to gain access to the two nuts that allow you to slide the transaxle up or down a little. BUT, when you remove the big plate, you lose all support there and are totally guessing which way to go. Fine.
Before you loosen anything, see if you can bench press the transaxle up a little and determine if you free up the shift rod in the main shift tube or jam up the shift rod in the tube. If the gear shift is resting heavily on the bottom of the tube, you need to move the nose cone mount DOWN in relation to the transaxle, then tighten the 17mm nuts. As you reinstall the 17mm bolts under the big plate, it will suck the transaxle up further than it was before. You'll see.
I can't remember if yours is a '72, but VW did a fine screw up there for a few years where they had unusually noisy transaxles in some cars. My squareback has one. They changed synchronizer designs and they changed the number of teeth (whilst maintaining the same ratios) in each gear set to quiet things down.
