4 Hydraulic failure in the gearbox
The 5th gear is unreliable or the gearbox is slipping (Gear 4)
Reasons for preliminary judgment:
1 Valve body clutch pressure relief
Determine the main reason: because the transmission oil temperature is too high and the heat dissipation is not good, all internal parts are damaged and the valve body is stuck.
Replacement parts: valve body, input shaft, output shaft, planet carrier assembly, small repair kit, friction plate, oil grid, etc.
