What transmission is this?
I have my 1966 GMC 910 (Canadian) 1/2 ton pickup at a transmission shop for having the transmission rebuild. They told me it was a rare and unusual transmission in it?? It is a 4 speed manual on the floor. They said they were having a lot of problems finding internal parts for it. They told me the trans was a MNNP420 transmission. I have never heard of this and can’t find any info online either. Anyone know what this is???
