Disadvantages, breakdowns and problems of Jatko JF403E
All the problems of this reliable automatic transmission are somehow related to oil pollution.
Clutch wear products are carried by grease along the box, clogging everything around
Clogged valve body solenoids cause jolts and jerks when shifting
A leaking pump seal is a sign of torque converter lockup wear.
Due to oil starvation, it quickly cuts the splines of the rear planetary gear set
