L/R Mod.valve E4OD 96-up

L/R Mod.valve E4OD 96-up '96-Later The Low/Reverse modulator plunger valve uses line pressure to control the position of the Low/Reverse modulator valve. Due to continuous oscillation of the plunger valve, wear occurs at the ID of the sleeve, allowing line pressure to leak to exhaust. The Low/Reverse modulator valve is prevented from properly supplying regulated line pressure to the Low/Reverse clutch, which can cause slippage, burnt clutches, and loss of engine braking. Symptoms: Burnt Low/Reverse clutch Low pressure at Low/Reverse clutch No engine braking Cause: Wear at the Low/Reverse modulator plunger valve sleeve bore due to continuous oscillation. Correction: Restore critical clearances and recover hydraulic control by installing Sonnax Low/Reverse modulator plunger valve kit.
