Disadvantages of the Jatco RE4F03A gearbox

• All problems with this automatic transmission are related to wear due to clogged solenoids;
• First, dirt from worn-out clutches spreads throughout the system;
• Then it settles in the solenoid valves and channels of the transmission’s hydraulic control unit;
• Then, due to oil starvation, the mechanical parts of the automatic transmission suffer.
