subaruowner840 Posted September 30, 2005 Author Share Posted September 30, 2005 melayout hit it right on the head. mine only occurs during moderate accel (30% or so). If I go WOT, the car shifts fine. I would rule out ATF, being that my car is only 3mo old and has roughly 5K miles on it. I would describe the shock & shaking as a feeling of something not engaging properly. Like if you had a manual trans with a warped clutch. You'd let out the clutch and the car would shake and vibrate as a result of the clutch not properly engaging with the flywheel. Our problem feels a bit like that - except it only happens with the 2nd-3rd shift and we have automatic trans. Link to comment Share on other sites More sharing options...
melayout Posted September 30, 2005 Share Posted September 30, 2005 Actually, subaruowner840 mine occurs at any throttle position between partial throttle and full throttle, I just used these 2 points as an example. Especially at WOT, the 2nd->3rd shift is violent and disturbing as opposed to your smooth/fine shift. I keed I keeed Link to comment Share on other sites More sharing options...
Slickvic Posted October 2, 2005 Share Posted October 2, 2005 When I rode with the Tech, using the Subaru Select Monitor we narrowed it down to the engagement of the torque converter lockup clutch that always occurs on the 2nd->3rd shift. Did'nt the tech think this was unusual? The torque converter lockup is not supposed to engage at the gear shift. The lockup should only occur when cruising at light or moderate engine loading. Having the TC lock up on a shift would be the worse than dumping the clutch on a manual transmission. Link to comment Share on other sites More sharing options...
GTsleeper Posted October 2, 2005 Share Posted October 2, 2005 I would have to agree Slickvic. The tech should of made a note to at least look into it, talk to a engineer, something! It could be as simple as them re-flash the trans module. That would probably take time to do that though, remap-ect. The TC is electric, controlled via trans module- based off of many sensor values to control it. I havent had that problem--10k. So Ill see what happens. I think 4 everyone with the problem, u should be on Subaru's ass. If it doesnt get fixed it will definitly damage something, & not just the tranny! The bad part is when something does happen the car might be out of warranty! So at least go and have notes done, work order or some kind of evidence that shows u took it in for that complaint. Multiple times, multiple people, in or out of warranty- they should take care of it! Recall? Link to comment Share on other sites More sharing options...
CyKocess Posted October 3, 2005 Share Posted October 3, 2005 I have the same symptoms as melayout. I notice it more between 1/2 and WOT. I'll have to see what my dealership has to say when I get a chance. They're pretty good to me even after I was a big PITA for them with my '05 WRX. I've established with them that there's no BS when I say I have a problem. We'll see this time around...... Link to comment Share on other sites More sharing options...
melayout Posted October 3, 2005 Share Posted October 3, 2005 SlickVic - I remembered that before that issue I always experienced a drop in RPMS on the highway while accelerating, which I attributed to the TC locking up. So I took the car for a drive today to try to replicate that on the highway and I never saw that drop in RPM. So it looks like you could be right. I will bring it up to the tech and district rep and hopefully we can test another LGT so we can compare. Thanks again. I keed I keeed Link to comment Share on other sites More sharing options...
RoundBoy Posted October 3, 2005 Share Posted October 3, 2005 i seem to only get it if I am in the 'manumatic' mode, when I am actually controlling the upshift myself. Letting the car accelerate in drive seems to have a minor to no bump during the shift. Link to comment Share on other sites More sharing options...
rallynut555 Posted November 14, 2005 Share Posted November 14, 2005 Any progress concerning the 2nd to 3rd gear shudder? I have the same problem. Link to comment Share on other sites More sharing options...
subaruowner840 Posted November 14, 2005 Author Share Posted November 14, 2005 No it still seems to do it. I've recently noticed it is more likely to happen after taking a turn. I think it might have something to do with the limited slip rear differential or center diff. I think it might not be a problem in the sense of something breaking or faulty rather just a problem in that it's annoying. Link to comment Share on other sites More sharing options...

subaruowner840 Posted November 14, 2005 Author Share Posted November 14, 2005 keep us updated melayout. I know we've discovered your LGT problem is probably more severe than mine...however, you never know when that might change! Link to comment Share on other sites More sharing options...
Rommel Posted November 14, 2005 Share Posted November 14, 2005 Not sure if this is also normal, do you guys feel any engine breaking while you're on sport mode when slowing down? I started to notice this after installing the UP & DP. Link to comment Share on other sites More sharing options...
melayout Posted November 14, 2005 Share Posted November 14, 2005 It aggressively downshifts in Sport mode and engine braking should be more prominent since it doesn't rev-match. I keed I keeed Link to comment Share on other sites More sharing options...
spacejunkiehsv Posted August 7, 2006 Share Posted August 7, 2006 Was there ever any kind of resolution to this "studdering" or shift problem? Link to comment Share on other sites More sharing options...
melayout Posted August 7, 2006 Share Posted August 7, 2006 Yup, they finally fixed it for good. Had to open up the tranny and change the low range sun gear. They said it was worn out. If the 5EAT automatically rev-matched on downshifts, I don't think this would have a been an issue. I keed I keeed Link to comment Share on other sites More sharing options...

Did you do a lot of "manual" downshifting with your 5EAT, or are you talking about rev-matching in normal auto mode? Link to comment Share on other sites More sharing options...
subaruowner840 Posted November 29, 2006 Author Share Posted November 29, 2006 Update! I was the original post to this discussion. I recently had my 30K service done which involved draining (not flushing) the AT fluid. So far so good. No more shuttering or shaking. If it starts up again I would consider a flush of the fluid and maybe a good AT fluid additive. Based on what I experienced and the results of changing fluid I can assume my shuttering and shaking was do to the AT fluid. Link to comment Share on other sites More sharing options...
mcsquish Posted December 2, 2006 Share Posted December 2, 2006 Well, I got my 2005 LGT reflashed, and no difference. It still stutters I may just have to look into flushing the AT fluid. ________ VAPIR NO2 VAPORIZER Link to comment Share on other sites More sharing options...
jim1969 Posted May 22, 2009 Share Posted May 22, 2009 bumping an old thread. Anyone have this when slowing down, like coming to a stop? Either my 4->3 or 3->2 downshift is hard. New tranny btw. Link to comment Share on other sites More sharing options...
TurboOutback Posted December 8, 2013 Share Posted December 8, 2013 Subaruowner840, we have the same drivetrain, although mine is on a outback. I have the exact same issue shifting from 2nd to 3rd. How did you fix it? Link to comment Share on other sites More sharing options...
TurboOutback Posted December 8, 2013 Share Posted December 8, 2013 Nev mind. I just read your update. How is your car running these days? Link to comment Share on other sites More sharing options...
