My sister has a '99 Sable with similar symptoms. On the 1-2 shift it feels to me like it slips, then it catches and jerks, sometimes hard enough to squeak the tires just a bit. But not all the time - sometimes in driving it 8-10 miles it will do it maybe once pulling away from a light, or do it 3 or 4 times from light to light - then it won't do it again for a while.


Someone I talked to suggested it might have the wrong trans fluid in it, and she had it flushed and refilled, but it didn't change much - it didn't do it for a while that I knew of, then started in again.

I don't know if it's even worth fixing given how cheap I see these go for at the state surplus auctions, usually with a bad motor or a bad trans, and this car has a lot of coolant leaking issues too (it's had three heater cores put in it in the five years she's had it; in all the years I've had cars I've only had to put a core in one car and it came to me that way).

But it would be nice to have an idea what causes this problem and if it's a simple fix or a sign of major trouble.
