Converting to automatic transmission

What's wrong with the 2 sticker? I'd have to think switching over would be a huge hassle.

 

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.....

 

Find an older non electrical Allison. Finding flexplate might be a bear.

 

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

 

If it's a 2 stick 6 speed, that was the "lazy man's" truck.
