January 22, 200917 yr where could i find a chart for early to late 90's, i need to know ratios of trans and rear diff.... thanks Neo
January 22, 200917 yr 95 - 99 2.2 manl = 3.9 2.2 4eat = 4.11 2.5 manl = 4.11 2.5 4eat = 4.44 the early 90s had no apparent pattern. i think 94 was the same as 95 but not sure. turbos were likley different than others of the same year and trans????
January 22, 200917 yr Author There is a good pdf on this site here. I hope it helps. am I reading it right or that is for 5spd and 6spd trans only? thanks though i already have that but i wanted a chart for the ATs only johnceggleston posted the info that can help me thanks alot Neo
January 27, 200917 yr Author Another quick question... Are the gear ratios the same for the Imp ATs up to 00 also??
January 27, 200917 yr Another quick question... Are the gear ratios the same for the Imp ATs up to 00 also?? logic says they would be or at least a very close variation. the most i can figure out is that subaru makes 3 ring gears, 37, 39 & 40 teeth and 2 pinion gears, 9 & 10 teeth. (plus the odd ball 11 tooth pinion for the svx). these gears allow for the gear ratios we are most familiar, 3.7, 3.9, 4.11, 4.44, but there are other possible ratios. so my guess is imprezas use some combination of these existing gears. you can do some research at http://opposedforces.com/parts/ and find the actual part numbers for the gears in the diff in question and compare them to another. but, i may be wrong, so do your homework.

January 27, 200917 yr Author cant seem to find info on the imprezas 4eat gear ratio now i just need to know if it is a 4.11 or what grrrrr
January 27, 200917 yr cant seem to find info on the imprezas 4eat gear ratio now i just need to know if it is a 4.11 or what grrrrr My 97 impreza L with 4 spd auto was 4.111, does that help?
January 27, 200917 yr Author ok thats a start.. now how about 2 yrs ahead? i am looking specifically for a 99 impreza thats the tranny i am going with for my lego
January 27, 200917 yr ok thats a start.. now how about 2 yrs ahead? i am looking specifically for a 99 impreza thats the tranny i am going with for my lego I'm not sure. But I know that when I had a question about this one time, I called the dealer and they were able to look it up for me. So maybe you could try that? I mean I would think it would be the same, but of course I don't know for sure
January 27, 200917 yr i look at the rear diffs listed in the opposed forces parts lookup website and the diff ratios appear to be same as the legacy for the late 90s. 2.2L man - 3.9 2.2L 4eat - 4.11 2.5L man - 4.11 2.5L 4eat - 4.44 1.8L was the same as 2.2L, and pre 95 was not necessarily the same post 95. but again, i just looked this up and i may be wrong, or the web site may be wrong.
January 27, 200917 yr ok thats a start.. now how about 2 yrs ahead? i am looking specifically for a 99 impreza thats the tranny i am going with for my lego you need to check more than just the dif ratio, the 99 legacy trans changed in the early part of that manufacture year. in 99 they went to a trans with a TZ1A2ZJEBA (outback) part number rather than the 98 version TZ102Z2DBA (outback), the TZ1A2Z... is a phase 2 trans. this change in the legacy trans included a wiring change. you need to find out which trans the 99 used and which trans your other car used. impreza may have changed a year earlier or later (earlier i think?). using the "new" phase 2 trans will require a lot of wire splicing and figuring out. what year are you putting the trans in? does the 99 have a spin on trans filter? compare the wiring connectors to make sure they match. Edited January 27, 200917 yr by johnceggleston
January 27, 200917 yr the impreza 97 2.2L AWD a/t, was a 'new' phase 2 trans. this means a 99 would be also. what is the year and model of the car you are putting the trans in?
January 27, 200917 yr 95 legacy uses a TZ102ZAAAA. you can use any legacy 2.2L trans from 95 - 98 as long as it starts with TZ102ZA... impreza part numbers for the same time frame are similar but some check is in order. but you can probably use a 95 - 96 (maybe 97?) impreza 2.2L trans as long as the trans part number starts with TZ102ZA...., but this crossover is unusual and it's going to take some research to be sure it will work. there is a chance you can use an impreza as early a 93, but 95 is usually a break point so i would stick with 95 - 96/97 as long as the trans part number starts off with TZ102ZA.....
January 27, 200917 yr you can also probably use a 96 - 98 outback, LSi, or GT trans if you get the matching rear diff. these trans have the 4.44 gear ratio. i say probably, because i don't know if the 95 TCU will work well with the 96 - 98 TZ102Z2.... trans. if possible, stick with a 2.2L trans.
January 27, 200917 yr Author this trans form the impreza is from a 2.2 i am just waiting for the guy to call back with a trans number
January 27, 200917 yr have you looked here? www.car-part.com you'll have to search for legacy, 95, 96, 97, 98 etc., as listed above, but you'll have lots to choose from. sort your search by 'distance'. a 450$ trans in town costs the same as a 300$ trans you have to ship for 150$. these guys list one for 175$, Alliance Auto Parts USA-NY(Woodside) Request_Quote 1-800-323-4500 Edited January 27, 200917 yr by johnceggleston
January 27, 200917 yr by the way, that was a 96 legacy 2.2L A/T. if the jy hears you ask for a 95 they will not quote a 96, their interchange software thinks they are different. do your research on line and then call the jy and ask for the year trans you have seen they have.
January 28, 200917 yr Author ok i am getting that 175 trans this is the trans code TZ102Z2ABA will it work?... do i have to change the TCU hmmmmmmm
January 28, 200917 yr ok i am getting that 175 trans this is the trans code TZ102Z2ABA will it work?... do i have to change the TCU hmmmmmmm if the part number you listed is correct, it has the 4.44 diff ratio, you will need the matching rear diff. the trans part number you listed is for a 96 outback, (2.5L or 2.2L, same trans, the only time a 2.2 had the 4.44 rear diff). you need a trans part number which starts with TZ102ZA ...... you cannot have a '2' right after the second z, it has to be an 'A' after the second z.

If all he needs is a matching rear diff, that's awesome! That just means lower gears for off road!!
January 28, 200917 yr Author hmmm here is the correct number.. my typo... sorry TZ102ZABAA its a 4.11 right? Edited January 28, 200917 yr by njdrsubaru
