Finally, we can use the stock shifter that IH blessed us with, but use it to operate a GM overdrive automatic transmission! This new shift gate comes with good illustrated instructions. You will need a drill and basic hand tools to complete the conversion, and thats it! Takes longer to remove and reinstall the shifter, than it does to modify it.
-Note that first gear is not manually selectable with this gate! We tried, but the arm on the transmission had to be so short to make this all work, that it made it hard to shift, and cause too much stress on the cable. We were afraid that cable longevity would be sacrificed, and decided to let it work 2-3-OD-N-R-P, and leave first gear out.
