I have an 08 Rubicon with a 6 speed transmission. I lost a bearing. I have a 4.5 R/E long arm lift and am running 35's. I only have 12.000 miles on it. It is not my daily driver but I don't wheel it that hard. The dealer is going to replace it but the rub is, it is on national B/O. Is there a problem with the 6 speeds that I haven't heard about? No new or reman's are available. Estimated ship date is 4 weeks from the time the it was ordered. Anyone else experiencing problems with their 6 speeds?
