Take it to auto zone and have the codes read free. This will tell you what quit probably the speed sensor which is on the trans. I have this same problem from my 1995 Stratus, I've been told it's the speed sensor, there are 2 sensors, (input and output) they run about $20 at an autoshop.. trying to find where there located with out the manual is another thing! ;) Anyone? I would say it is the output speed sensor located on the transmission. If your standing in front of the car looking at the car it would be on your right hand side. There is 2 on that side and its the top one. I changed mine by reaching up from underneath the car. Try installing a new gas filler tube gas cap. My "check engine" light illuminated, the transmission started shifting erratically, and my cruise control would not work. I installed the new gas cap and it fixed the problem. It seems that they all work in conjunction with the vacuum system--which the old "O-ring" on the original gas cap had gone bad and theere was a leak in the vacuum system.
Bad speed sensor.
change the speed sensor located at the end of the tail shaft on passenger side of tranny
When working on a car engine, it is important to have an engine diagram. A Dodge Stratus engine diagram can be found in a Dodge forum online, or in the repair manuals at Auto shops.
check your speedometer sensor located back left of engine bay on top of the transmission
Nope, bet it was the other way around... Your speedometer stopped working and your check engine light came on. A broken speedometer (don't know what car so I can't pinpoint it) will cause a whole bunch of codes.
the speedometer on my 97 toyota camary stopped working and the check engine light came on why
I think you need a speed sensor
There are several possibilities why the speedometer is not working. The VSS, vehicle speed sensor may have failed or become unplugged. The speedometer may have failed, or the ECM, engine control module, may have failed or there could also be wiring issues.
The check engine light only comes on for something that affects emissions
2002 Tahoe speedometer quit working and trans will not shift, ABS light on. NEW ANSWER: You need to have the engine and transmission scanned with an OBDII engine scanner so you can find out what speed sensor has gone bad / quite working.
You need to have it checked for codes to know what to diagnose.
Yes it can cause erratic shifting. But not an engine miss fire. You need to find out why the engine is missing and running bad and when you fix that problem then I'm sure the transmission will start working and shifting correctly.
