4eat questions

[oooo]

My 1995 subaru legacy has the 4.11 auto mated to the 2.2 engine and I have outback struts and springs lifting it with 28.3 inch tires on it, the gearing is off as is the acceleration, with 4.44 gears I would be back in the stock torque curve and also improve my gas mileage, I was wondering if the 4eat out of a 1996 or 1997 legacy outback or legacy gt with 4.44 gearing would work on my car. I know that it would physically bolt up because subarus are like legos but are the sensors and transmission harnesses's etc, the same, and will it work with my 2.2 engine, since the 4.44 came only mated to the 2.5 engines. And I will also be getting the matching rear 4.44 diff. hopefully all the sensor locations on the transmissions are the same.

 

1. Is it a plug and play situation, can i just bolt up the new 4.44 tranny

and use my old transmission harness

 

2. does the transmission have a computer that I would also have to get

and if it does would it work properly when connected to a 2.2 engine

computer, since it came connected to a 2.5 engine computer

 

3. I know they redesigned the 4eat in 1998 to make them more efficient and changed the filter design and a few other things, would one of the

newer 4.44 autos out of the 1998 to 2000 also work or do they definately

use a different harness, sensors, and sensor locations

 

4. If it can be done should I just use one out of a 1996 or 1997 because it

would be less of a headache.

 

5. If it can be done can somebody list all the parts I would need for the

swap

 

Sorry for all the questions but I'm a noob when it comes to cars and trying to work and modify them and since this is my only form of transportation I want to make sure it will work before I spend my money on something and not have anyway to get around for awhile.

 

Thanks in advance

all 2.2L engines with automatics have the 4.11:1 final drive ratio, except the 96 2.2L outback. all 2.5L engines with auytomatics have the 4.44:1 final drive ratio. now i'm not a automotive engineer, but i think the lower the number the more efficient/ higher the gearing, the higher the number the more powerful / lower the gearing.

 

changing trans will improve your torque/power but not your mileage. larger tires / wheels tend to improve mileage, fewer rotations per mile, i don't know what too large would do. how does a 28.3" tire compare to the stock tire on an 97 outback, 205/75/15?

 

it is plug and play, the trans will bolt in, plug in, and run just fine. don't change the TCU. these are programmed for the size and weight of the car, how it is supposed to run / shift (and the engine, little bit i think, but not much, you can put a 2.2L engine in a 2.5L outback and it runs just fine). example, if you put the TCU from an leg wagon in to a leg sedan it will shift later and stay in 3RD more, i think.

 

starting w/ 1999MY the outback auto trans were phase II (legacy 2.2L may have started in 98) and had the external filter . the wiring harness changed, and more speed sensors were added, 2 more i think. so stay with the phase I trans 96 - 98.

 

any trans part number starting with TZ102Z2... will have the 4:44 final drive and will plug in and run. the 2nd '2' after the 2nd 'Z' indicates 2.5L engine. all you need is the trans and the rear end. but brfore you put any money into this i would compare the tire sizes. if the new are substantially larger than the old i'm not sure the making the final drive change will help. the difference between 4.11 and 4.44 is only about 8%. if your tires and 25% larger then .....? it might be cheaper to get smaller tires.

i think there were some 92-94 legacys with a 3.9 final drive in the 4eat. i had this problem while trying to find a differential for my 90 leg that has the 4.11 FD

typically, the 3.9 final drive was in the 2.2L manual transmissions in the 1990's. the 2.5L manual outback & gt had a 4.11.

I have a 4.44 turbo 4EAT with a matching 4.44 VLSD rear I would be willing to sell.

Send me a PM if interested, I am in PA.
