I am attempting to rebuild a model a604 transaxle out of a Lebaron with a 3. 0 V6. I am not a professional rebuilder and I received this transmission already disassembled. I have an ASTG manual but am confused about the different snap rings. The book refers to tapered, waved and flat snap rings. I have looked these snap rings over closely and cannot figure out how to tell the difference. Do the end cuts have some significance?
