Dealer has seen the truck 3 times and still has no clue what is going on. The first time they could not make the truck make the sounds. The clutch was replaced on the 2nd go around and the problem continued. The 3rd time they replaced the transmission fluid and are sending me on my way since they have no clue what to do next. Please let me know if you have had a similar problem with grinding, squeaking and a vibration in the shifter area. This is a 6-speed manual transmission.
