Question Dual-Range Transmission

I've been reading on some Aussie 2004 Forester reviews that manual non-XT's come with a dual-range transmission. Is this true in the US? I've never seen this.

I'm guessing this is because of the lower kW's in the non-XT models???

Probably that as well as gearing. In the UK, even the base Impreza wagons come with dual range.

Thanks bluesubie

Is this a hi/lo shift leaver located somewhere? button?

Does anyone know the final gear ratios between the FXT and ones with the dual-range transmission?

Has nothing to do with the torque output. They come with a dual range so they're more useful in actual off-road conditions. AKA, "stump pulling."

No North American subies have come with dual-range gearboxes since maybe the Brat....

I was wondering about the final ratio ... thinking about revs vs speed

Do they make the top gear on the AT a lower ratio to offet worse fuel economy through using an AT ... or just to get lower revs for same speed (when compared to MT?)

I just don't like how high my revs are when I'm doing 70mph

The dual-range transmissions found on Subarus (in every market other than North America) are only found on MTs, and not ATs. The biggest concern with the DR on turbo models is that people would "drag race" while in low range. The big problem with this (as I understand it, and I haven't been able to source a cutaway yet) is that the reduction gear is on the INPUT side of the transmission. Although this keeps things very light and compact, it also multiplies the torque TO the transmission. I'm sure most of you can appreciate that this would be bad in a higher power application. It is interesting to note in support of the above, that the low range used to be much lower, before the more recent breed of engines came to be.

What is REALLY neat about the Subaru DR though, is that it is fully syncronized, and thus can be used "on the fly". Just push in the clutch at any speed, and pull the little lever. It's like having a 10spd. Try that on your Suburban! The unfortunate part about the newer DRs, is that the center is not manually lockable. I have been told that they are equipped with a slightly more aggressive viscous center to make up for it, but I can't substantiate that claim.

Incidentally, the last DR in NA was the Loyale (1994), and not the BRAT. I think the RX Turbo's transmission was the coolest Subaru ever built. AWD (as opposed to fixed 4WD), low range AND a manually lockable center differential (the only other Sube getting that was the XT6, but it didn't get DR).
