I'm really been thinking hard about purchasing one of these M22z transmissions. I would like a lower first gear. My 2.52 and 3.36 rear is tough on my clutch on the steep hills we have. Been researching autogear and 5speed.com sites. Don't know who I should go with.

Has anyone here installed one in a Firebird?

How do you think a M22z with a first gear 2.98 and a 3.36 rear gear would perform. The output drive ratio would be 10.01 for 1st gear which would be a power horse off the line. Would it be too much?

Here is how the final output drive ratio compares. The biggest difference is 1st gear. For a performance car, the recommended 1st gear output ratio is 10.

M22Z
1st gear final drive ratio = 10.01
2nd gear final drive ratio = 6.85
3rd gear final drive ratio = 4.93
4th gear 3.36


Current M20
1st gear final drive ratio = 8.47
2nd gear final drive ratio = 6.31
3rd gear final drive ratio = 4.91
4th gear 3.36

What do you all think about this swap?
