Yes. Changing the lever ratio and/or the spring load in the servo will as well. Changing those may also effect the 2/3 shift though.


If the results don't match the theory, change the theory.

The outer accumulator spring has NOTHING to do with cushioning the 1-2 shift but it's a good idea to have it for other reasons.

HI
I am referring to the spring that you normally remove and replace with a blocker rod when you install a manual valvebody, I thought the stock spring was for cushioning the shift

Yes, that is the outer accumulator spring and it only cushions the application of the rear clutch, has nothing to do with the 1-2 shift....oldest myth in the Mopar world.

I had A&A Transmission build the forward manual valve body for my 518. I asked them for 2 important things, first was to take some of the 'hit' out of 2nd gear and second, to take some of the 'hit' out of reverse. They did both (I don't have a clue how), but they did. It goes into second firm, but without a hit that will pull the tires loose. And it does not bang into reverse even when the idle is a bit high.
