subaruVWnut Posted November 29, 2005 Share Posted November 29, 2005 I need a tranny for a 96 OBW but not sure if 97-99 versions will also work. Does anyone know which year auto transmissions are interchangeable with a 96 OBW. It has the DOHC 2.5L engine. Warren C. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted December 2, 2005 Share Posted December 2, 2005 The newer ones "should" work. Only thing you'll need to verify is the final drive ratio. You need to find one that has the same final drive ratio as your 96. If not, you'll need to swap out the rear diff to match the final drive ratio in the transmission.

subaruVWnut Posted December 3, 2005 Author Share Posted December 3, 2005 The newer ones "should" work.QUOTE] Can you be more specific ...." the newer ones" covers a lot of territory..... 9 years..... I've heard tat 96-mid 99 were essentially the same but my dealer parts guy says they all have different part #s. I have a spare 4EAT from a 2000 OBW. Looks essentially the same.. but ???????????? Other than diff ratios...I'm also concerned about incompatibility of TCU to ECU signals and speed sensors. How can you determine diff ratio...someone told me there was a number, sticker, stamp on the rear diff that told.....but checking two in my yard.....no such thing.

Legacy777 Posted December 3, 2005 Share Posted December 3, 2005 The newer ones probably is from 96ish or so and up. The phase 2 4EAT had a few more inputs like torque converter speed and one or two other things. As long as the two transmissions have the same pin outs, then I don't see why they wouldn't work, regardless of what part # it has. You may want to get a subscription for http://techinfo.subaru.com and find the TCU pin outs for the model years of transmissions your looking at. You should be able to verify whether the TCU pins are the same or not. Also, it'll have final drive ratio info. Quote Link to comment Share on other sites More sharing options...
