We have a periodic problem with this lift truck "coming out of gear" in forward and reverse. The shift lever is in forward but the lift truck stops moving and will not move again until the shift lever is moved to the neutral position and back into forward or reverse. Our local dealer has not seen this before and has not been able to come up with a solution. They changed the seat switch but it made no difference. This only occurs once every 15-30 uses so it is not something we can predict when it will occur. This machine is only 5 years old with 118 hours on it. Has anyone else experienced this type of problem?
