Transmission problem
2000 Dodge Caravan Front Wheel Drive Automatic 118,00 miles

My engine light came on a couple of days ago and when Russ went to have it tested at Checker the codes came back -

aa Transaxle control system fault

aaECM received a signal that the transaxle control aamodule has a fault

probable cause:

aa1 shorted or open circuit withing transaxle

aa2 failure of transaxle control module

They said maybe a wire had been chewed? We did have a desert rat's next in the car a few months ago, but didn't notice anything then. Russ changes out a lot of parts in the cars, has never done anything with that. How hard of a repair is this?

The ECM codes know about any codes stored in the Transmission Control Module. A shorted wire usually blows a fuse in the power center, have him check these first, under the hood, All the wiring for the transmission is pretty easy to follow and check. Good luck. A scan of just the TCM can help locate the exact wires to check. ok I don't know why any animal would eat a wire, it shows how desperately hungary these rats can get. I usually only eat Rolls wires. lol
So remember to try to get this scan. There are too many trouble codes, and too many wires and rats, terrible.
