1994 Dodge Caravan
My Daughter's 1994 Caravan will not shift into overdrive. The Tranny was
rebuilt a couple of months before she bought it. The motor does reach normal operating temp. What can be the cause? Buster |

The Tranny was rebuilt a couple of months before she bought it. The motor does reach normal operating temp. What can be the cause? Buster" ******************************************* How many miles are on the vehicle, which engine? Was it a reputable shop that rebuilt it? There are many upgrades required to be installed into these during a rebuild, including the controller. I had all kinds of problems with a 604 when they failed to replace the controller -- which had undergone at least two upgrades. In other words, when I finally took it to a reputable shop, they mentioned that this 'rebuilt transmission' was still using the first generation controller, where by that time it should be the third -- so naturally the unit was not compatible with the upgrades hardware included in the rebuild kit, and wouldn't control it properly. I'm not saying there's a high probability that's the problem with yours, just that there are a LOT of upgrades on those, both inside and out. Are you sure it's not shifting into overdrive, or if it's the torque converter lockup not working? |

I have one with a similar problem. It seems to overrev in each gear, and doesn't shift into overdrive. If I drive a few miles, then shut it off and restart it a minute later, everything works great. One time on the freeway, it went into neutral - engine just reved up until I let off the gas. Coasted down to 40-45, then it started working again, but with the no-overdrive, overrevving problem until I turned it off/on again. The previous owner had the overdrive solonoid replaced, with no improvement. A dirfferent shop removed the computer to try a substitute one, and claimed the problem went away, and stayed away after re-installing the origional one. I bought it, and the problem came back a few days later. Could this be a speed sensor or temperature sensor problem? Any other ideas. |
