LT1 Stock gears?
Not my year model or gear box it was 2:73's stock rear end from factory. there are two different types of gear boxes for 93 models with different gearing and ring and pinion. Most people dont know that and when i tell them my car came stock with 2:73's. Down below is a copy and paste from a memeber OBE1 95Z28
Q: What are the stock transmission gear ratios and torque capacities?
A: The following were available by year:
Year Model/Optn 1st 2nd 3rd 4th 5th 6th Final
---- ------------- ---- ---- ---- ---- ---- ---- -----
1993 Manual/M28 3.36 2.07 1.35 1.00 0.80 0.62 2.73 (GU2)
1993 Manual/M29 2.97 2.07 1.43 1.00 0.80 0.62 3.23 (GU4)
1993 Auto/MX0 3.06 1.63 1.00 0.70 -- -- 2.73 (GU2)
1993 Auto/MX0 3.06 1.63 1.00 0.70 -- -- 3.23 (GU5)
1994 Manual/MN6 2.66 1.78 1.30 1.00 0.74 0.50 3.42 (GU6)
1994 Auto/MX0 3.06 1.63 1.00 0.70 -- -- 2.73 (GU2)
1994 Auto/MX0 3.06 1.63 1.00 0.70 -- -- 3.23 (GU5)
The '95s and later have the same ratios as the '94s. Aside from the CAGS provision and different gearing/input shaft (on the post 93's), all of the 6-speed transmissions are basically the same.
