The automatic transmission in my 1992 Chrysler Dynasty is getting worse. When cold, it won't go into gear unless I give it some revs, then it might go into "limp mode" (2nd gear I think, 80kph max) until I reboot the car. Otherwise it shifts decent, not jerky or clunky. It was flushed a few years ago and the fluid level is good. I've added Lucas Oil transmission fixer fluid but it didn't help much.
The car is a beater, so I'm not into spending too much... it's a common problem with one of the clutches or seals or some such, the same thing happened in my 91 Dynasty and eventually the tranny died when a helpful shop filled it with DEXRON (wrong fluid specified by helpful Chrysler, there was a recall).
Any ideas how to improve it? Other than driving it off a cliff...
