[TR] Transmission noise - TR3A w/Overdrive

[Perry Hammock]

well, tuesday night, after a stinging Pacers loss, I was driving home.
 Stopped at a corner, made a right turn in 1st gear and got a noise like th
gearbox equivalent of the card in the spokes.  Soon as i shifted to second,
no noise. Nor 3rd or 4th.  Bur every time in 1st, the noise is constant,
tied to speed, and sounds like you had something hitting against gear
teeth.  Pretty loudly, not to be ignored. But constant, consistent, not
like something loose randomly bouncing around in the case.
Drat.  THis  is a big driving weekend.  I am hoping to find something minor
( please God) when I take the top cover off tomorrow morning and start
poking around.  Any BTDT in the forum crowd?

Thanks in advance for your creative wisdom
