Re: muncie sm420
I did an NP440 swap for my 420. It has overdrive and there is one for sale on ebay right now for less than $1000.
It will bolt right up and there are several threads on the various forums on this tranny... I like mine with the .73 overdrive...especially if you drive the highways a lot...
