kc transmission in White South Dakotah is the choice for some of the
Greater
Midwest Classic members, and he is in the 700-800 $ range, with Allison
converter, and HD components.
Chuck: Can you define HD components. Brent and I and a couple of other
owners around here are overhauling a switch pitch transmission that will
eventually go into my coach (actually Brent is doing the work and answering
all of our questions while we gawk). The transmission is from a 67
Eldorado. We will be swapping in a number of parts from a 78 transmission
(3/4 inch oil pump, planetary gears and a few other things). The switch
pitch has been altered by another GMC owner as per specifications supplied
by Don Brown, which changes the angle of the switch pitch blades to 30
degrees from 21 degrees. This lowers the stall speed to about 2800 (from
3600) and reduces the multiplier gain slightly. Don maintains that it helps
to keep the switchpitch running cooler so that he can leave it in the "s
witched" position going up long hills. He has over 100,000 miles on his
transmission and has had no trouble with it.
I have had discussions with a number of people about the pros and cons of
the five Vs the six clutch pack and things like that. I am most interested
in knowing what others feel makes a HD transmission for the GMC.
