1999 forester namual trans.- changing the "low" ratio???

Recommended Posts

hi guys

i want to change the "low" ratio in my forester.

the original reduced speed is 69%, my goal is 50% but if it's impossible- i am ready to compromise to 55-58%.

i am looking for a kit to buy. if there is not- a design will do. if i won't get a design- my mechanic will open the transmission (and i am going to add a "phantom grip" to the front diff. i already have one in the rear that works great), and i will design new gears (i am a mechanic designer).

if anybody knows anything about it (possible or not, names of people or workshops that have alredy developed such), please respond.

thank you

What exactly do you want to do?

 

Does the overseas foresters come with a dual range 4WD transmission? Is that what you're talking about by changing the low range?

Check out 33% lower low Range gear sets out of Australia...

 

If your Forester is already Dual Range, I will put money on that kit working for you.....It is Made to fit the older 5 speed Hi-Lo boxes out of 85-90 cars, but I've been into a few AWD 5 speed boxes, and the front end Internals Look the same....

 

I can't remember the outfit down there Selling or producing them, But if you go to

http://www.AUSubaru.com and inquire about it I am sure they can tell you if it works or not...

 

Good Luck and Let us Know if it does Work...:)

hi Josh and John

my forester already has duel range transmission.

by using the "short handle" the speed of the whole "normal" range is been reduced in 31% (the ratio is 1:1.45).

i (actually, my mechanic will do it) want to open the transmission and replace the "low" range gears, to acheave a bigger reduction, so i (my forester) can "crawl" slower on technical surfaces.

my goal is 50%, but since i have heard some warnings about risking mechanical parts (in one hand), and impossibility of that operation (in other hand), i'll may compromise on 55-58% (if there is a technical possibility).

i prefere to buy a kit, but if there isn't any, or the reduction is too small, i'll open the transmission and design the gears myselp (i am a mechanical engineer).

so, John, if those 33% mean 33% reduction, it isn't enough.

i'll be happy to hear more replies.

thank you
