2002 dodge stratus 4-cylinder auto car will not shift out of low gear?

Answer 1

this assums you have checked your Transmission Fluid, and are only using chysler trans fluid. DO NOT USE DEXRON OR FORD TRANS FLUID. If it is not pure Chrysler +3 or +4 you must change it and do not allow any one even a mechanic tell you otherwise.

If your transmission will only use one forward "gear" then it is one of these usually, #1 could be your transmission relay FUSE, this operates the transmission shift pack RELAY. The fuse is covered and in front of the battery positive red cable. the FUSE for trans relay will be clearly marked. CHECK IT! if fuse is good put it back and move on to next problem area.#2 "there are two relay covers" one in front of the red battery cable connection and one rear of red battery cable . The rear cover needs to be removed to see the TRANSMISSION RELAY. it is clearly marked. $11.99 at most any auto-parts store if you get a universal relay, bring yours for comparison. dealer also has them for much more. #3, If new relay will not correct your problem then change trany fluid AND filter AND gasket. use only ATF+3 OR ATF+4. road test. If its good great if not ,#4 have a shop REVERSE FLUSH your transmission, Not all shops will do this, get in your phone book and call around, and ASK QUESTIONS do not go TO just any shop, ask if they have equipment for this, lots of Dodge dealers can do this .#4 If you don't want to put out the 120 bucks for the flush then put a brand new shift pack with two new gaskets it should cure your problem, if not have your tranny rebuilt or buy new, hope this helps
