CONDITION:
Vehicles containing HYDRA-MATIC 3T40 (RPO MD9) transaxles may exhibit a harsh clutch engagement (garage shift) when the gear selector is
moved from "Reverse" to "Drive" on initial start-up.
CAUSE:
To reduce the harsh garage shift concern ("Reverse to Drive"), the hydraulic circuit at the manual valve was redesigned to allow reverse fluid to exhaust
without restricting its flow. The forward clutch stack (625 & 633) was also modified to improve the apply feel during initial engagement.
