Which transmission do I need?
This will be dependent on several factors such as power, weight, how the vehicle is used, rear end gear ratio, etc.
The GM TKX transmission is offered in the following ratios:
2.87 - 1.89 - 1.28 - 1.00 - .68
2.87 - 1.89 - 1.28 - 1.00 - .81
3.27 - 1.98 - 1.34 - 1.00 - .72
Flywheel
Next, pick out your flywheel. For Big-Block Chevy’s there’s no difference in the bolt-pattern. However, for Small-Block Chevy’s, the flywheel-to-engine bolt pattern changed in 1986 when the SBC went to a single-piece rear main seal. All generations should have six bolts, however, the spacing varies based on if it’s a single- or dual-piece rear main seal.
- The tooth count of the flywheel is limited by the size of the bellhousing and needs to match your starter.
