mikeamondo Posted January 2, 2008 Share Posted January 2, 2008 I understand the 4EAT tranny in our daughter's 95 Impreza has a self protection feature which prevents it from shifting into 4th gear when cold. I just wanted to check to make sure that's correct.... our 90 Legacy should have the same tranny, and I've never noticed it in that car. The Impreza will run fine thru the first three gears for about 5 or 10 minutes, then will finally start shifting into 4th. Is that normal? thanks!

SUBARU3 Posted January 2, 2008 Share Posted January 2, 2008 Yes, you are correct. It can be a few miles too, till it finally shifts, (depending on outside temp). Todd Quote Link to comment Share on other sites More sharing options...
bratman2 Posted January 2, 2008 Share Posted January 2, 2008 The 93 Legacy that my daughter owned would take up to 10 miles to shift into 4th on cold mornings. Probably still took 5 on warm days. She put nearly 75k miles on it so I say normal. Quote Link to comment Share on other sites More sharing options...
nipper Posted January 2, 2008 Share Posted January 2, 2008 Its not a self protect, its to help the engine and tranny warm up faster for emissions and such. It's normal, just be nice to it for the first ten minutes or so. nipper Quote Link to comment Share on other sites More sharing options...

I'm already having to replace the fuel filler tube where it's leaking like a sive, and then I noticed the tranny... thought we might have picked up a lemon. Good to know the transmission is acting normally! --Mike Quote Link to comment Share on other sites More sharing options...

Mike I think that also the torque converter will not lock either until it's warmed up a little. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted January 2, 2008 Share Posted January 2, 2008 sounds sort of normal. not sure if different years have different responses but 10 minutes seems a bit long considering it hasn't been brutally cold in morgantown yet. i have a 97 impreza OBS and it has not seemed to take that long to shift into 4th, but maybe i just didn't notice. i'm in morgantown now as well. if you ever needed me to look at something for you we can probably arrange that. if it does the same thing every time, then you don't have anything to worry about, if it starts changing and acting differently then that would be odd. i would check the fluid level and flush/replace the ATF as well if you have no idea when it's ever been replaced before. does this car have an external/alternate transmission cooler on it? that may delay it getting the temps up in the winter?

classact2575 Posted January 2, 2008 Share Posted January 2, 2008 Mine does that when it's really cold (say <20), but it takes less than a mile to shift. Torque lockup, on the other hand... :-p Basically that's all I post about. Quote Link to comment Share on other sites More sharing options...
nipper Posted January 2, 2008 Share Posted January 2, 2008 A fluid change may not hurt either nipper Quote Link to comment Share on other sites More sharing options...
rverdoold Posted January 2, 2008 Share Posted January 2, 2008 I think that also the torque converter will not lock either until it's warmed up a little. As i have noticed my torque converter only locks after 20 to 30 minutes of driving with speed above 75 km/h. This is done by keeping 80 km/h (+- 2500 rpm in 4th with not locked TC) then when TC locks the rpm drops to +- 2250 r) If i now give little extra throtle the revs dont increase (a lot like 250rpm) but more in a slower way, it feels if the engine is directly driving the wheels. If TC is not locked the revs increases somewhat 250 rpm. I expect this to be normal to the gearbox, also the longer warming up time. (on outside temperatures of aroun 10 C). am i right ??? And when it doesnt want to go to 4th i never pass 2500 rpm to treat it well as just common sense that it cant be good to go higher. Quote Link to comment Share on other sites More sharing options...
