hey I'm trying to change my gear ratio and I don't know how to handle the 1.00 in the trans and ratio fields.
basically I changed my gearset and chain to the 3:69 setup from the 2:93 setup.
car is a 2006 grand prix gxp with the 4t65e transmission. If anyone has any direction please help.

I believe you have to play with the other settings in the speedo tab.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
