I am new on here to get some input as well on the 5th gear issue. I had a new transmission put in by Bob Baker, Kia Mitsubishi in Carlsbad, CA on January 7, 2008. The dealer knew I was flying out to pick the car up and drive it across the county to Delaware. That night as I started on my way and as soon as I got to Yuma, AZ my 5th gear started slipping out all on its own. I had no choice but to keep going as I was already scraping to make it with the funds that I had for fuel. I have put a total of 5,000 miles in 4th gear and sometimes holding 5th gear in. The dealer always avoided my calls and it's not like they would have gotten a place around here to fix it. Anyways, I have heard about the loose nut before, and also thought to mention that when I left the dealership it was like the whole shifter setup was offset more to the right/passenger side. The whole shift setup was centered before I got the new transmission. Could that have any reason that it's pulling out of 5th since it wants to go back to the center? And reverse sometimes grinds or I will have to slide it into 5th and then into reverse... Would appreciate any help anyone has to offer. - Rob
