Anwart Posted October 16, 2007 Share Posted October 16, 2007 Hi There, i had to replace my Automatic transmission on my 1996 outback AWD.it was knocking alot the mechanic Guy suggested to change it. we did the job till now 8 times. he had to get them from used and not new. the last one is for an 2000 impreza, turbo.it works fine but not on AWD i had to put the fuse in the box of FWD. he decided to change the rear gear, it still have the same problem. it vibrates alot on 1st and it jams on AWD. he said we have to find the right back gear for this transmission. i asked him how to do so he said we have to try since there is nothing written that tells you this gear goes with this transmission. can anyone help me how to identify what gear should go with my transmission or how to identify it. Thanks in advance. Regards. Link to comment Share on other sites More sharing options...
porcupine73 Posted October 16, 2007 Share Posted October 16, 2007 Hi Antwert. Yes it sounds like the final drive ratio of the transaxle you are installing does not match the ratio of the rear diff. Check out these articles: Correct axle ratios Outback Gear Ratios If you have some info about your transmission serial # I know there are people here who can tell you the ratio, for U.S. spec vehicles anyway.

Thanks for the valuable information, do you think there is a chart to identify the transmission with the right rear gear or only with the serial No.?? it's a bit late now to open the hood and try to take the serial No of the transmission. i will take it tomorrow and give it back to you. Thanks again for the great help. Link to comment Share on other sites More sharing options...
idosubaru Posted October 17, 2007 Share Posted October 17, 2007 you've replaced the transmission EIGHT TIMES? that's jacked up. remove the front differential drain plug and count the teeth on the gear. over here that would be a bad swap - the 99 and up transmissions have some major design differences and there could easily be differences between a 2000 and 1996 transmission. over here a 2000 transmission will have a spin on oil filter, the 1996 will not. you may be dealing with wiring issues, more on that later. jack up the rear of the vehicle and turn the rear wheel. count how many times the driveshaft turns for each turn of the wheel. 41 turns of one to 10 turns of the other gives you a 4.11 gear ration. 44 turns of one to 10 turns of the other gives you a 4.44. i would imagine those are your two options 4.44 or 4.11 i wouldn't waste my time trying to find the gear ratio out, just start counting like i said about. automatic transmissions do not have a lot of information out there about final drive ratios, it's asked all the time on here and it's even tough to get answers here in the states. i would not assume that what we got here is identical to what you got there, so it becomes even worse for you. i'd start counting to be sure. also check the duty C and FWD circuitry, you may be mixing and matching transmissions with different wiring. you should be able to do some basic wiring/circuitry testing - continuity and the like to make sure your duty C and FWD switch wiring is the same.

Anwart Posted October 17, 2007 Author Share Posted October 17, 2007 Thank you GroosGary for your Reply, my outback is an American, it was imported from the US. may be thats why we're having hard time to find the right gear for it. the transmission on it now is an Impreza turbo 2000. i'll try to do the counting and check what it is. lets say it's an 4.11 ratio which gear will fit on it??? Thank you Regards. Link to comment Share on other sites More sharing options...

Hi Again, i got the numbers on the Transmission and the rear diff too transmission: TZ102YBABA-CF 793254 the rear gear has 2 letters painted with white color: TP Thank you for the great help.

idosubaru Posted October 17, 2007 Share Posted October 17, 2007 lets say it's an 4.11 ratio which gear will fit on it???. i'm not sure what you mean. yours is probably a 4.44 gear ratio - so your rear differential is probably a 4.44. you'll likely need a 4.11. but....again, you've done this "8 times" you said? with the same transmission, different transmission, different rear differentials? i don't know if anyone is going to come up with the final drive for you just based on the part numbers, i've seen others try to do that and not get anywhere.

Thank you Regards. Anwar Link to comment Share on other sites More sharing options...
porcupine73 Posted October 17, 2007 Share Posted October 17, 2007 I can't remember who had that chart of the ratios...was it johnceggelston? Link to comment Share on other sites More sharing options...
johnceggleston Posted October 17, 2007 Share Posted October 17, 2007 I can't remember who had that chart of the ratios...was it johnceggelston? his part number TZ102YBABA-CF is a a little different from most i've seen. the 'y' is new to me. legacys (90-98) with AWD, all have a nother 'z' there. maybe because it's from an impreza.? there is an end wrench article telling how to check the front and rear diffs to make sure they match. generally it says to put one side of the car on jackstands, unplug the trans wirring connector, this locks the AWD unit in 4WD, and start the car in neutral, brake off. now with the AWD unit 'locked', if you turn the rear wheels , the front should match them turn for turn. if they don't the diffs don't match. http://endwrench.com/images/pdfs/CorrectInfo.pdf if it's really an american car, i thought the 99-00 impreza and the 99-oo 2.2L legacy used the same trans, part number any way. a 96 outback should be a 4.44 final drive. my guess is that the 00 2.2L impreza is 4.11. just this week some one posted a hard to read list of info for trans and final drives, all of them, and i can't find it. it was on legacycentral i think. i'll look again. found it: it's hard ot read but .... according to this thread, '00 imp 2.2L is 4.11, and 2.5L is 4.44 http://bbs.legacycentral.org/viewtopic.php?t=13500&sid=7add370daf15909c801cba58%20f69c2cbd the tranny chart is just for manual trasnsmissions. it's ok to bookmark both of these. http://www.northursalia.com/techdocs/trannychart/trannychart.pdf Link to comment Share on other sites More sharing options...
idosubaru Posted October 17, 2007 Share Posted October 17, 2007 i'd start counting the revolutions like i mentioned earlier. or try the tip above about locking the transfer clutches. do not wait for trans info, like i said, i've seen it time and time again and it's very difficult to get exact ratios on the automatics. i'm surprised that after all of these issues you haven't just gotten the exact right transmission. for the cost of 5 transmissions and all that work it seems like you could buy whatever you want. another easy way out of this mess is to swap to a manual transmission. then you have no electronics or TCU's to deal with.
