1997 Plymouth Breeze; the transmission was slipping. Sent it to the shop. They replaced gears, solenoid pack, speed control sensor, almost the whole tranny. When I got it back, check engine light came on within 5 miles. 2 codes- speed control sensor and auxiliary output something. Anyway. The tcm fuse keeps blowing even with the key off. Upon further inspection we saw that the nut within the tcm was missing and that housing was damaged so we replaced the tcm. Still no help. We traced the wires from the tcm fuse and tcm relay to the wiring harness on the tcm and found no damages. Help! We are at a loss. The shop is willing to fix it, as it is under warranty, but they are stumped too. Oh and they said they used a relay that they knew was good and it didnt help. I dont know what else to do. Please help

Replace the fuse with a pair of jumper wires connected to a 12 volt light bulb. A brake light bulb works well, but if you need to allow more current to flow, a head light bulb can be used too. The bulb will be full brightness when the short is present. Move wires and unplug connectors until the bulb goes out or gets dim. That indicates the short has been isolated or removed from the circuit. Keep working your way down the circuit until you narrow down the cause of the short.

Ok. We did that and narrowed it down to the red wire with black tracers. It goes from fuse box to tcm harness. It also splits off into transmission shift solenoid which the mechanic just changed. (1)are there any wires inside that shift solenoid that could have been crimped when they installed it? There appears to be transmission fluid leaking there so either there is something crimped in there or the gasket is not sealed good. (2) is there a way for me to check the solenoid and see if it is a good one or does that have to done at a shop?

You would have to ask that! I replaced a number of transmissions at the dealership but never a solenoid pack. The connector is on top so it would seem unlikely that a wire got pinched, especially if it worked for a while. How about removing that connector to see if the short goes away? In the words of one very sharp Chrysler trainer, "We not only sell you the parts, we sell them to you pre-broken". Recently-replaced parts are always a good first suspect.
