Good day, this 76 custom "logger truck is getting real interesting! I got an Alberta in-transit permit for 3 days to drive this truck for service that I cant get in our little town and took this truck on an 80 km trip to "try her out" before the safety inspection on thurs. I got on the hyway and found the speedo to be reading a lot faster than my road speed. This speedo is still in mph and is reading 80 mph with an actual speed of 60. So it is 20 mph out.
I got home and pulled the speedo cable out of the trans and found a red 16 tooth gear. This truck has a dana 60 4.10 ratio I also checked my 79 s/c that also has the same 4.10 axle and found a longer blue 16 tooth gear.
so my question is: is the 16 tooth red gear correct for a 76 c6 trans? is the internal gears different between a 76 and 79 trans? this has me stumped!
