Ok, I bought this bus in southern Virginia and towed it all the way back to Connecticut. Starting Saturday morning, it was a very long weekend. But, such is the measure of my devotion. Now, although I do most of my travelling in the forward direction, reverse does come in handy sometimes. I can get it into reverse, and nurse it back a few feet, and then...DEAR GOD! My ears are assaulted by the most appalling gear grinding noise. A friend of mine says that there is some linkage to adjust which may solve my problem. Anybody?

Sounds like a reverse syncho or shift fork problem to me. Don't know of any linkage that could be adjusted to fix it. My first car (74 Thing) had the same problem and was only cured by replacing the trans. Good luck! Andy

Arthur,

Andy may be right, he has had a bad experience with his transmission ;-)

However, I would still check the following: Engine mounts. Top transmission mounts. Front transmission mount. The flexible gearshift rod coupling (just in front ot the trans) The two gearshift rod coupling screws (just in front ot the trans) The centre gearshift rod coupling and screws (behind the front axle before the rod enters the body) The front gearshift rod guide (in front of the front axle) The gearshift lever assembly and adjustment (in the cabin on the front floor) (this last item is probably what your friend is thinking of)

One of the best methods to check most of this, is to get a friend to move through the gears, while you are underneath checking these items. What you are trying to do, is to make sure your getting full "movement" when selecting reverse.

There's NO shifter linkage adjustments on that vehicle-- if you hear crunching sound just before going into reverse = synchronize issue! A crunching just before neutral -- sounds like reverse shifter fork is worn down. - several ways that you can tell - one is drop the tansmission -- remove the end piece and look or you can remove just the shifter end. not the housing! take a rag and a pair of visegrips. wrap the rag around the shaft, clam visegrips to shaft with rag to protect shaft, then move fore to aft to shift into a gear - you feel a click or loose at all -- shifter fork needs replacing! most wrecking yards will have many worn out reverse shifter shafts! Buy one new!!
