idosubaru Posted January 18, 2008 Share Posted January 18, 2008 not sure what you mean, can you tell us why you're asking? when driving, the TCU doesn't "default" to anything, why would you want it to default to 1st gear when you're doing 80 mph down a mountain grade? i'm confused.... when not driving...well it "defaults" to whatever you have it in..neutral.....

EVOthis Posted January 18, 2008 Author Share Posted January 18, 2008 just a school project....have a list of things i must find and the default gear is one of them.... Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted January 18, 2008 Share Posted January 18, 2008 Hm...do you mean the 'failsafe' or 'limp home' gear? I think that's 2nd gear. Quote Link to comment Share on other sites More sharing options...
EVOthis Posted January 18, 2008 Author Share Posted January 18, 2008 yeah i guess you could say that it is the failsafe gear....whatever gear that the i guess the computer puts the tranny in when there is a problem.... Quote Link to comment Share on other sites More sharing options...
nipper Posted January 18, 2008 Share Posted January 18, 2008 Its bit more complicated then that. Subaru when in limp mode limits the car to 50 mph (4500 rpm), and disables the lockup torque converter. I also think it wont go into 4th gear, but ill have to check. The car also becomes gutless. This will occure with a loss of both vss sensors, if one VSS reads dramaticlly different then the other (like a broken axle). The ignition timing is modified to prevent engine damage. The failsafe mode for the AWD is full 50/50 split when there is a duty c failure. The limp home mode can be forced by driving with the test connectors under the dash hooked up (the infamous green connnectors). These connnectors are used for flashing the ECU. I'll read through the manuals and see what i can find. Soobys dont go in this mode often, so i cant recall exaclty what they do aside from the RPM cut and road speed.
