Well, its that time of year again and my TCCM is out again. The last one from the junkyard lasted over a year. Does anyone know what the difference is between all of the part numbers for this part? They all have the same numbers but have AE, AF, AG, or AI after them but they look identical. I would like to source another one before the white stuff falls.

Thanks

 

What are your symptoms/lights? An info panel Ck4wd light is not always the TCCM.

 

Same as all the times before. No lights at the switch and no trouble codes.

 

the two digit alpha code attached to the part number indicates who made the part for Chrysler, nothing more, if the number matches the part is the same.
