I dont know the gearing or any of the specifics.
Remember the stock H1 for 2006 comes with a 5 speed Allison stock, my truck is a 1998 with a 4L80E.
The company that is going to do the conversion for my H1 does them for a small unit in the military with huge success.
I just have to supply him with a solid transmission. He does the 5 speed and has not done a 6 speed before. But he states that it would be the same type of install, he would have to flash the ECU a little differently is all.
The big question is 5 speed or 6 speed.
Using a 6 speed is the big unknow because I cant find anyone who has done it. My truck has limiting factors that might make the 6th speed useless. Here they are: The truck wieghs over 10,000 lbs and it is extremely NON AERODYNAMIC. I usually dont drive any faster than 60 to 65 and the average would be more like 60
