We have a TS14 Scraper that has the 3461 Allison transmissions in them. We had a spare 3461 transmission, however one is a four speed and the one in the scraper is a six speed. I was told at one point from some old timers that you can make a four speed a six speed by changing the balls around in the valve body. I have not been able to find any info out there about this. Can anyone help us with this?
Thank You
