Rastrahouse Posted September 19, 2007 Share Posted September 19, 2007 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. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted September 19, 2007 Share Posted September 19, 2007 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.

xrturbo Posted September 19, 2007 Share Posted September 19, 2007 I think they are 4.11s. That trans is the same as the 99-01 RS trans. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted September 19, 2007 Share Posted September 19, 2007 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.

johnceggleston Posted September 19, 2007 Share Posted September 19, 2007 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.

xrturbo Posted September 20, 2007 Share Posted September 20, 2007 4.44 is an auto gear ratio in the US Quote Link to comment Share on other sites More sharing options...
xrturbo Posted September 20, 2007 Share Posted September 20, 2007 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. Quote Link to comment Share on other sites More sharing options...
