Re: M40 adjustments
You can also buy aftermarket kits with different weights - similar to distributor advance weights - that will alter shift points.

Re: M40 adjustments
Correct - I have a "CD" coded low perf M40 in my 72. By adding a shift improver kit (not a full blown shift kit) and tweaking these weights I was able to get it to shift where and how I wanted it to. It is a little bit of a trial and error process but is not overly difficult. It has performed flawlessly behind a GM crate 454/425 for 8 years now.

Re: M40 adjustments
Thank you for the information. It is the original CW transmission and it shifts very well now. If it is adjustable, I was going to play with it to see if I could make it bang a bit harder.
