The input shaft is 4th gear. So as long as it mates with the layshaft I can't foresee a problem.
Both the -025 and -050 input shafts each have 23 teeth.
The T5 cluster set arrangement is INPUT/3rd/2nd/rev/1st, and then a removable 5th gear.
So to work out gear ratios, there are two steps involved - working out the input ratio and then the speed ratio. In this case:
- The 23 teeth of the input shaft times is divided by the number of teeth on the first cluster wheel = the input ratio.
- The number of teeth on the corresponding cluster is divided by the # of teeth on the nth gear wheel = the speed ratio.
- Then to get the gear ratio for a given gear, you multiply the input ratio by the speed ratio.
That's the Readers' Digest version of how to do it - a more detailed explanation
appears here. Interesting, hey.
And just to make things even more interesting, there are at least 15 different combinations of cluster sets listed for the WC T5 gearbox family... with varying numbers of teeth and torque-handling ability. I say 'at least' because the Falcon box with the 3.25:1 first gear doesn't seem to be a ratio set available on US T5 boxes, so the cluster set in it may be an Aussie special.
