The 4 speed on all of them are.......

2.88
1.91
1.34
1.00
(I don't know reverse)

The overdrives can be different. Z51 cars got a 0.68 unit and all the others got a 0.60 unit. So your overdrive gears are....

Z51
2nd/ 1.30
3rd/ 0.91
4th/ 0.68

Others
2nd/ 1.15
3rd/ 0.80
4th/ 0.60

maybe you are confused because of the cold weather you experienced the last few months.
