Running the ATKX bin.

3rd gear TCC lock up occurs at 27mph.

4th gear at 26.

Seems like the extra 2-250 rpm drop when the TCC locks up in 3rd at normal/moderate acceleration bogs down the engine a little more than it should.

Oh, running the 700r4 and 3.73 rear.

Bump the 3rd mph to 32 mph maybe?
