"Identifying a transmission by mathematical calculation
By placing the transmission in 5th gear and turning the input shaft 10 times and measuring how many times the differential rotates, you can theoretically figure out which transmission you have from the following equation:
10 / (5th gear ratio) / (Final drive ratio) = (# of turns of the differential)
Examples:
CRX HF
10 / .694 / 3.250 = 4.43 turns of the differential
CRX DX
10 / .771 / 3.888 = 3.34 turns of the differential
CRX Si
10 / .771 / 4.25 = 3.05 turns of the differential
DOHC ZC
10 / .878 / 3.888 = 2.93 turns of the differential
SOHC ZC (same gearing as CRX Si)
10 / .771 / 4.25 = 3.05 turns of the differential
SOHC ZC ZXi
10 / .771 / 4.437 = 2.92 turns of the differential
Obviously this method doesn't help you differentiate the normal DOHC ZC transmission from the SOHC ZC ZXi transmission, so you will also need to do a test in 1st gear.
10 / (1st gear ratio) / (Final drive ratio) = (# of turns of the differential)
Examples:
DOHC ZC
10 / 3.250 / 3.888 = 0.79 turns of the differential
SOHC ZC ZXi
10 / 3.250 / 4.437 = 0.69 turns of the differential"
