Spotting the Changes to Ford 6R80 ’15-Later Valve Bodies

Verify OE valve and sleeve measurements before use.
There are some small diameter and length differences that can cause fit and pressure issues if mismatched into the wrong application. It is recommended to measure the locations shown here to verify that the correct OE or replacement part is fit into the appropriate application during rebuild.
Application | A | B | C | D | E | F | G |
---|---|---|---|---|---|---|---|
ZF6 Gen. 1, 6R60, 6R75, 6R80 ('09–'14) | .645" | .629" Dia. | .495" Dia. | .568" | .378" | .629" Dia. | .550" Dia. |
ZF6 Gen. 1 w/ 053 Separator Plate | .725" | .657" Dia. | .511" Dia. | .649" | .378" | .657" Dia. | .586" Dia. |
ZF6 Gen. 2 | .804" | .629" Dia. | .511" Dia. | .725" | .418" | .629" Dia. | .562" Dia. |
6R80 ('15-Later), 6R100 | .645" | .629" Dia. | .511" Dia. | .568" | .378" | .629" Dia. | .550" Dia. |
Wear is commonly found at different areas in Ford 6R80 pressure regulator bores. Wear at the sleeve end causes high line pressure leading to broken drums, pistons or other parts, as well as restricted converter/lubrication flow. Wear at the spring end of the bore allows low line pressure and lube/TC fluid to exhaust leading to a burned converter clutch and premature bushing failure. Sonnax oversized pressure regulator valve kit 95740-46K restores valve-to-bore or sleeve clearances so the pressure regulator valve can maintain correct pressures.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.

Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
