Transmission Bummer

[Daniel & Kathy Gibson]

Ok, so I get Amphi up past second gear for the first time, and there appears to
be some
tranny problems here. Here are the symptoms:

1. What appears to be a rotational grinding noise
2. The engine and tranny start to shake above 20 or so mph

It is faitly quite shifting as far as gear whine is concerned, but the two upper
gears have
that grinding sound. I jacked up the back end, and put it in gear and revved it
up some,
and sure enough, there was that shaking and noise.

So, here is what I pose to the group: Any ideas what part of the tranny may be
causing
this? Possibly u-joints? Fix or replace tranny?

This is a real bummer. Hopefully the fix is not too expensive, as I have spent
major $$$
(for me anyway!) so far, and cash is running a little low! May even ruin my
plans to go
swimming this Spring (D'oh!)

Any tips, advice, suggestions are welcome!

Thanks

1st & most simple to check: Make sure both U-Joints
on each rear axle are aligned the same, not 90 degrees
apart. Yes, I made this "dumb" error several years
ago & received lots of bounce over 20 mph or so.
Simple, but took me quite a while to figure out.

Good Luck.

Dan,
It's hard to tell. Are your axles lined up correctly? The u joints one the
tranny end and the hub end should be in the same position. I've not experienced
this but I've heard from others this can cause an out of balance or maybe a
shake. Take a look at your axle shafts.
