I have an 87 Olds 98 with 130,000 miles. When I am driving in OD up a
hill, the transmission will start to chatter. I can usually relieve
it by shifting back to Drive. However, it even chatters some in
Drive. I changed the transmission fluid about 12,000 miles ago but
the fellow simply flushed and did not change the filter. I have tried
a couple of the additives but they don't seem to help. Any advice
will be appreciated.

Have the dealer or a good transmission shop look at the transmission
and follow their advice if you want to keep the car. If the car has
130,000 miles on it and the first fluid change was at 118,000 miles
that is probably the cause of your problems. And the solution will
probably be a rebuilt gearbox.

It sounds like a situation where the tranny should downshift.

The noise might be related, engine "ping" due to lugging. High-octane gas
might reduce it (and doesn't cost much to try).

Unfortunately I don't have any tips for DIY tranny adjustment on anything
newer than a Power-Glide.
