allfritz123 Posted 1 hour ago Share Posted 1 hour ago My 18 speed in my 1999 E7-460 CH truck is giving me problems. I have never had any problems with the transmission before. I have used this truck for about 5000 hours and it has been solid. I dumped my load at an elevator and was driving back empty to get another load. After shifting the 2180 into high (I call it 4th gear) 17 or 18, it started to pull and then started to make noise and it seemed like it wanted to disengage. The gearshift itself remained in its proper position and I didn't have to hold it or anything. I stopped and inspected the drive shafts and there was no problems there. I drove it home in 3rd gear. The hi-low and range selector work for all the other gears. It is a 4th gear problem of some sort. 4th gear in low range is fine - the problem is only occurring in the high range. When I drove it home using the other gears, everything is quiet. What could be the problem?
