Calvin rebuilt his tranny three times because of faulty reproduction parts. Several others have had the same results.
Another good source for NOS is Army Jeep Parts in Levittown,PA. �Good selection, good parts, good help with questions but fairly high prices. �It was worth it. �
I must add to what Carlsjeep stated about my three tranny overhauls. �During the first overhaul I unknowingly installed all new less expensive foreign gears and shafts. The second overhaul was to replace all the poor quality parts from China, Taiwan, and elsewhere through Omix-Ada (who supplies most distributors and retailers). �There is a thread about the problems others and myself have encountered on the old forum. �The third disassembly was simply to replace 3rd gear synchro blocker ring--I had not left adequate end play for the output shaft upon assembly fter the second overhaul. �I thought I was being real smart and assuring that my tranny would never pop out of 2nd by having minimal end play. �It was due to that, that the synchros wore out in less than 2,000 miles. �After replacing the blocking rings my transmission now handles perfectly. �It is 100% NOS except for seals and bearings. �
