ATP TO-33

ATP TO-33 is a transmission and transfer case rear output seal. It works at the rear output of a transmission or transfer case where the output shaft or drive yoke exits the housing.

Application / fitment

TO-33 is used on rear outputs requiring a flanged metal-clad output seal. Fitment should be confirmed by housing type, seal position and yoke sealing surface; dimensions are listed in the technical section.

• part type: flanged metal-clad output seal
• position: rear transmission output or transfer-case output
• selected transfer-case applications: NP205, NP207, NP208, NP231, NP233, NP241, NP242, NP243, NP249
• selected transmission applications: T10, Super T10, Muncie M20 / M21 / M22, Ford T18 / T19 and GM TH180 / 180C / 3L30 1969+
• mounting design: flanged version, without outer boot

Install the flange squarely and inspect the shaft or yoke sealing surface. A worn yoke can continue to leak even after the seal has been changed.
