TransGo Performance offers direct clutch springs for a variety of automatic transmissions, including more than a dozen Mopar models. Certain Dodge, Ram, and Jeep vehicles fitted with small or big case transmissions often come in with faded overdrive direct clutch springs, as well as burnt overdrive direct clutch plates. This spring is used to apply the overdrive direct clutch. Once it fades, clamping force is reduced, directly compromising the holding ability of the overdrive direct clutch. This leads to complaints of slipping or no reverse, reduced or no coast braking in manual 2nd or 1st gear, as well as burned up overdrive direct clutch plates. The TransGo overdrive direct clutch high-temp springs are an improved design that resists spring fade. These top-quality OEM replacement springs help prevent slippage as well as direct clutch plate failure. * Corrects/Prevents/Reduces: -- Slip in reverse -- Burnt overdrive direct clutch plate -- Reduced or no coast braking in manual 2nd or 1st gear
