I currently have a 1978 r Mack twin stick wanted to see if it’s possible to put an automatic transmission in it
I'm sure it's possible but the aggravation of finding an automatic that could pair up to that engine would be way more than shifting 2 sticks lol especially one that's in good condition
Are you thinking of an auto shift or putting in an Allison? Auto shift should require an engine with an ecm.
anyone with money, can do anything. transmission, transmission to engine adapter, transmission cross member, drive shaft(s), plumbing, maybe wiring... yup, it can be done. or do a complete resto-mod, with new engine, transmission, and all associated parts. yup.....money talks, BS walks.....
Curious as to why you would want to do that to a 78 Mack r. Is this a restored truck that you use as your money maker? If not, and it’s just a toy, getting rid of the 5 speed and putting a auto in it will break enthusiasts hearts everywhere
Maybe an automatic out of an 80's school bus? And some custom bell housing fabrication/ drive shaft length etc. Im getting frustrated just contemplating it.JMO
