If trans is jumping out of gear, that particular gear is worn from use. The beveled gears wear until they can not physically maintain contact. Split tractor at bell housing and again at rear differential to remove trans. remove top of trans and shifter. Remove main and counter shafts and replace worn gear and any bearings that show wear.
In a Ford 4610, you need to add the hydraulic fluid to the rear axle. The Ford 4610 is a 1989 tractor that retailed at close to $19,000.
The level check for the hydraulics/transmission/rear axle is pipe plug on the left side of the tractor just in front of the rear axle housing. Oil is supposed to be at that level with all hydraulics extended.
The vss is on top of the trans-axle, behind the engine on the passenger side.
There were three trans mission options. four speed five speed and 10 speed power shift with 2 reverse.
75W-90 or 80W-90 gear oil
When owning any vehicle it is important to know the types of fluids it uses to run smoothly. A 1953 Ford Naa Tractor uses SAE90 and SAE80 transmission fluid.
