I have a 2005 Dodge Ram quad cab 4x4 truck. It has the 24 valve Cummins engine,and an automatic transmission. While I was doing a routine trans service on it,I found what appears to be pieces of a large snap ring. By putting the two pieces I found together it appears to be about 2/3 of a five inch diameter snap ring. Any ideas where it came from? The truck drives,and shifts fine.How would these end up in the pan? I put the filter in place and reinstalled the pan,but I don't want to put the Mopar ATF 4 in it if it needs to come apart. It costs about seven bucks a quart,and takes twelve quarts. I hate to waste the fluid if the transmission needs to come apart.
