Per Tom's advice......

"Final drive should be between 3.0 and 2.50. If overdrive is .73 and your axle is 3.73, your final drive will be 3.73 X .73 = 2.72 (perfect!)!"

So your 3.55 x .72 overdrive =2.59 (so your in the ballpark)


Excellent. Thanks!

For anyone else who may also be interested, according to Tom's article, the range of gears for my T5 to be ideal in both first gear and overdrive (3.76 and .72) would be 3.90's to 3.55's. 3.90's being as low as you'd probably want to go for a good 1st gear, and 3.55's as tall as you'd want to go for a usable overdrive.
