I am looking for the ratios through the manual transmission from the flywheel to the axles (1991 Probe GL)
There are only four that Ford uses ( I have a 90 Mustang GT.) They are : 3.55, 3.73, 3.90, and 4.11. If you wrap through the gears quick its a 4.11 Look at you fifth gear rpm at 55mph. If its above 2500 its a 4.11 If its at/ above 2300 its 3.73. My 3.55 I'm at 1600 rpm at 55 in fifth. So, words of advice. Hope you found your answer
