New Holland tl90 transmission problem start it up put in first range then select one of the gears put it in forwards it creeps forwards about 1 foot then stops
But then put in second range firstgear and goes like a normal and also third range just having a problem in first range any ideas of where to look

Did someone solve this? I have same problem

My first thought would be to adjust the range shift linkage it sounds like you are not getting it into low range completely and as soon as it gets a load it jumps out of gear.

More likely an electronic issue. Power shuttle tractor, right? It COULD be a status switch or circuit related to to low range. Just guessing there. Best option is to go looking for error codes. New Holland software can retrieve stored codes. That might help narrow it down.

Problem solved. There is two sensor top of Gearbox ( under seat) Change both and it start work. First change only green one but IT not do anything but after change also grey it start work

Were there any shims or washers under the switches? If so it's best to keep them in the same place they came from. They can be involved in positioning of the status switch signal to computer monitors.
