4l80e question
o.k. here my question. you should be able to divided your Tos by your TIS to get your gear ratio.
1st gear tis 2003/ tos 812 = 2.4667 so close but i guess it good.
2nd gear tis 3054/tos 2069 = 1.4760 so second gear looks good.
3rd gear tis 3106/tos 3114= 0.9974 So the gears are close but little off.
o.d. grear. tis 2682/ tos 2678 = 1.001 should this be .750
I can see the rpm drop when the truck goes in O.D.
4l80e has been rebuilt, racing clutches and shift kit.
Here is my log file. what do you guys think?
