Question about 1999 Dodge Caravan
The transmission broke, I got it re-built. A few weeks later the check engine light came on and the transmission was having trouble shifting gears. I disconnected the battery; the check engine light turned off and the transmission was working fine again. But after driving the van for a while (about a day) the check engine light came on again and the transmission started "acting up".
I have done some online research and found out that there could be a number of things wrong. My guess is that it has something to do with the TCM. I think it is presently in what they call "limp mode"
Any advice would be greatly appreciated.
At a shop I worked at, another mechanic had actually replaced the tranny. Afterwards same thing (I may be assuming this is the automatic with overdrive). After running a test with a DRB II (Chrysler scan tool) we found out the output shaft sensor would work for a while then stop working, sending the tranny into limp home mode (when replacing the tranny he pulled the old sensors off and put them in the new tranny).They replaced a $2500 tranny over a $45 sensor.
This is just one of several things it could be, but it could be the cheapest place to start and is easy to diagnose with the right equipment.
