AOD adjustments?

First, you want to consider CAREFULLY if you want to do the shift shuffle - very hard on the trans!!! Plain AOD's (not AOD/E's which
are electrically controlled) are very hard to modify the shift points. There is one shift kit that allows you to do that to some extent. see www.baumannengineering.com - that will give you lots of good AOD & AOD/E tech info.
AOD's can be economically upgraded some, for mildly modified engines. I just did mine myself. Just by dropping the valve body to install a shift kit, you can also then add Art Carr's "zero leak" 2-3 shift accumulator and their A overdrive servo - helps with a couple of the AOD's weak points. Also check www.lentechautomatics.com - they've got a new slant on AOD shifting & valve body design. For just a plain shift kit, you want one with "cutback elimination" like Baumann's - that eliminates the reduction in internal shift pressure for the 2-3 and 3 to od shifts, & is generally regarded as about the best shift kit for AOD's.
