The AOD often has a long slide shift into second gear, intermediate clutch overheat, and/or direct clutch failure. In many instances the culprit is a worn 1-2 capacity modulator bore. The second clutch oil will leak past the outer balance spool and exhaust, creating insufficient clutch pressure. This can be seen on a gauge or valve body test machine as low second clutch pressure that does not stabilize and fill completely until the road speed allows a shift to 3rd gear. This results in 2nd gear slide and burned intermediate or direct clutches. Sonnax now offers an oversized 1-2 capacity modulator valve 76991-01K that restores the hydraulic integrity of the circuit. Kit includes an o-ringed end plug that prevents 2nd gear oil from exhausting through the bore. Three spring weights are included in the 76991-01K kit to allow for more precise shift calibration. Note: If you remove the OEM horseshoe clip and install a roll pin with guide hole drilled through the valve body, the plug can be removed and spring weight changed without pulling the valve body.
