We installed one of those Ruxtell transmissions in a Model A several years ago. I have to admit, I never checked the 3rd gear ratio. 2nd gear was quite a bit higher ratio then the stock Ford 2nd gear. The one we installed was NOS, and drove nice and quiet. The car we installed it in had a Twin -X two speed rear end, and 3.54 gears, and the car cruised at 75 effortlessly with the Twin X in overdrive. I have been involved with Model A Fords for 30 years, and have seen a handful of these transmissions. My only worry about owning one is a lack of available parts should it break. Just my 2 cents.....
