In 4R70W transmissions, common problems are intermediate roller clutch, overdrive band or forward clutch failure, traced to the O.D. servo pin wearing the case bore. The oil circuit which releases or holds the servo off is present as forward clutch oil in 1, 2, 3 ranges. If this release oil leaks through the case, it can cause the O.D. band to drag and/or forward clutches to overheat. If band overheating becomes extensive, it may not hold in 4th gear, which can allow a neutral condition and excessive roller RPM on a re-engagement of 4-2 downshift. Vehicles equipped with 4R70W/4R75W transmissions often experience failure of the intermediate roller clutch or mechanical diode during high-rpm conditions. Sonnax spiral retaining ring kit incorporates a spiral snap ring that is staked to a locking ring to ensure ring contact with groove during high-rpm conditions, eliminating blowout. A common complaint in vehicles with 4R7OW transmissions is low line pressure or throttle sensitive buzz, especially when hot. This is often caused by a worn main regulator valve. The valve frequently wears on the boost spool diameter and allows EPC (electronic pressure control) oil to leak to exhaust. This leakage results in poor line rise. When the oil temperature increases, the oil becomes less viscous and more leakage occurs. The two Sonnax replacement assemblies eliminate the above problems with a direct replacement main regulator valve. Another common complaint with these transmissions is poor reverse boost, often the result of a worn pressure regulator boost sleeve. 12 month or 12000 mile warranty with purchase of a new torque converter!
