Hello Sarah,

The Input and Output Sensors should have been replaced during rebuild.

The other cause for your problem is the TCM (Transmission Control Module) which is the computer that controls the transmission.

Transmission remains in limp mode and does not shift. After clearing the codes, the code for the EATX relay continues to show up. I have been told that the failure of this relay may cause the transmission to behave in this manner. So, hopefully, the easy fix is to replace this relay. However, I don't know where this relay is located, and no manual or diagram that I can find lists it. I suspect that it is probably listed somewhere by some other name that I don't recognize. I have seen under hood pictures that list both a safety shutdown relay and an automatic shutdown relay, but neither of those sounds like it would be the right relay. Now, of course, comes the actual question. Where is the EATX relay located on a 1992 Chrysler Town & Country van? Thank you for your help.

The closest I have is a '94 service manual, but it should be the same. There's two rows of four relays under the hood. On the shorter side of the fuse box, next to the latch, the relays are automatic shutdown, low radiator fan, fuel pump, and radiator fan ground. Just off center in the second row is high radiator fan, AC clutch, backup lamps, then the EATX relay. In the wiring charts they list the EATX relay as the "safety shutdown" relay.

There's a couple of different fault codes related to the relay. If you tell me the exact code number, I may be able to offer some suggestions.
