I found a 1990 Bluebird GMC shorty, and I’m trying to figure out what transmission it has—same old question, right?
Owner says it has an 8.2L V8 Detroit Diesel with Allison 3 speed automatic, hydraulic brakes, 194k miles.
I doubt is has a 3 speed, he sent a photo of the shift selector—is this an MT643?
The photo is pretty lousy, but maybe it helps?
Thanks in advance, Brad
