PJ724,I'm looking at a 1966 service manual it states different mph speeds for what body A or B and V8 or S6.Also rear gears.
So we will say a Coronet V8,3.23 gear. Either 904 or 727. Closed throttle/light throttle is 1-2 6 to 11 mph 2-3 10 to 15 mph.
Wide open 1-2 26-37 mph and 2-3 55to 67 mph.
I'm using a 66 service manual because it's what is in front of me. My 1969 manual is at the shop. If it differs I'll post it here.
I just removed a manual shift valve body out of my 65 (73 tranny) and installed a stock valve body with a B&M shift kit.
At first drive it shifted out of 1st at 28 mph and 44 mph out of second, light throttle. I am using a Mancini kick down cable kit.
Got a bit more adjusting of the cable to do. A bit more information than what you need, but what the heck, I'm improving my typing skills.
