RPM clueless

The top gear ratios in all 3 trannies is 1:1. So with a given rear axle ratio, they will run at the same RPM's. (The auto RPM's will be a bit higher due to slippage in the TC...) You need to have the rear axle ratio and the tire size to figure this out.

So the 4 speed just divides a set range into smaller divisions....no real advantage over 3 speed, at least as far as lower rpms @ high speed.

Were there many 4/floor paired up w the slant?
