A/T - Bind-Up On The 1-2 or 3-2 Downshift

BIND-UP ON THE 1-2 OR NO 3-2 DOWNSHIFT

Always check the valve body separator plate gaskets at the 3-2 exhaust hole.




On some models Hydra-Matic relocated the 3-2 exhaust hole in the separator plate. The 3-2 exhaust hole is right next to the # 4 checkball (figure 1).

If you use a valve body gasket (either upper or lower) that covers the 3-2 exhaust hole, you'll get a bind-up on the 1-2 shift and/or a no 3-2 downshift condition.

Keep in mind, even universal gaskets may have this hole blocked so make sure you check them all.
