Last nite while i was laying in bed, i came up with a cheap idea......
Why not install a standard transmission backwards behind my existing allison automatic?
If the "new" trans was a 4 speed, placing the trans in 3rd gear would significantly lower the engine rpm's at any given speed.
In the unfortunate event that the skoolie engine could not handle the new gear ratio, the aux trans could always be put back into high gear which would give a 1:1 gear ratio and act as if there were no modification at all.
What are YOUR thoughts on this project??
I found a 4 speed manual trans from a big truck for $100 at the bone yard.
