September 19, 200718 yr How do I find out what the gear and final drive ratios are for my 1999 legacy GT 2.5L 30A with a 5 speed manual are? I am trying to figure out the shift points for the best acceleration.
September 19, 200718 yr check out the search button. search for "gear ratio" and narrow the search down to new generation forum and a title search first. links to subaru MT gear ratios are around.
September 19, 200718 yr I think they are 4.11s. That trans is the same as the 99-01 RS trans. while i thought they were 4.44, i think that's only part of what he's looking for, that's the final drive ratio. many auto's are 4.11 and i thought the GT's were 4.44? i think he's looking for complete gear ratio charts.
September 19, 200718 yr he has a 5 speed 2.5L, it's 4.11. 95 - 99 legacy final drive ratios auto trans 2.2L = 4.11 2.5L = 4.44 5 speed 2.2L = 3.9 2.5L = 4.11 i have always assumed that the reason they lowered gearing in the final drive in the when they used the 2.5L engine was because generally the cars were heavier and needed it. but now i wonder if the final drive ratio isn't more associated with the wheel / tire circumference. in 96 when they introduced the 2.5L engine with the 4.44 final drive, every car they put in had 15" wheels (i think) outback, GT, and LSi. why would a more powerful engine need a more powerful final drive ratio? i can see where a bigger wheel would need one. just a thought.
September 20, 200718 yr The GT's were 16 inch wheels. You are probably right with the reasoning, more grunt for the larger outback tires, and a little more snot for the GT.
September 20, 200718 yr What is trranychart? click on the search tab at the top of this page and type in 'trannychart'. you'll find a link which will deliver a list of all manual transmissions, foreign and domestic with the gear ratios, final drive ratios and type of AWD center differential.
