Chryslers are the car's I've had to use it in the most..... Them and a few Escort automatics....
Directions:
Buy 2 can's of Trans X, the Pint NOT the Quart...
Remove a pint of tranny fluid.
Add ONE pint of Trans X and start the car and let it idle or drive it for a FULL day. (that's 3 hours or so in people talk)
Get that tranny on the highway and on the back roads and in the city and work it. NOT hard, just drive it up hills and down and stop sign to stop sign, regularly like daily driving...
Change your fluid and filter at that point. A fluid flush would be 100% better option but they cost about $80 bucks in this neck of the woods... I recommend it because it removes ALL the old fluid, not just what's in the pan.
Add 1/2 pint of the Trans X to the fresh fluid and the car should be driving fine after that. But ONLY if the tranny issue is because of not changing the fluid ever and having a bad varnish build up, which is generally the case in many cincumstances.
FE
P.S. It will NOT fix a broken tranny, and it will NOT break a good Tranny.
