In AODE transmissions, common complaints 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, the O.D. band can drag and, or forward clutches 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 OEM servo pin with Sonnax 76833E which has two (2) O-rings to positively seal against the piston I.D. and the case bore. This pin also comes with an optional washer to pre-load the spring for a firmer 3-4 shift.
