In AODE 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. Replace the OE servo pin with Sonnax 76833E.
