I have a replacement unit coming today. Should I be concerned about just plugging it in without knowing what caused the last one to blow or do these things protect themselves?

I bought a used auto-ECC off eBay yesterday. Should I be concerned about plugging it in without knowing what caused it to fail in the first place? Can a short in the wiring or one of the motors damage the ECC or will it just set a code and not work right? Should I take it to a shop and have them put...

To Ozark Lee:
Sounds like you replaced your Auto-ECC with a manual one..Did you buy it new or from a salvage yard? Any modifications required or does it plug right in? Any regrets about not going back with an Auto-ECC?

I pulled the codes and got 14 as well. I could not get the codes to clear using the usual procedure. I pulled the unit out and took the cover off.

Sounds like a problem with your solenoids. Before I had mine replaced on my 93 850 I was advised to try changing the transmission fluid. Didn't help...
Is it setting any codes?

Thanks, Alan. I was hoping I wouldn't have to buy a specil tool. Anybody else come up with a way to break this nut loose?
