Polaris Posted June 30, 2017 Share Posted June 30, 2017 Hey everyone, made a thread about this maybe a few months ago, everything was fine and it started up again. So basically I have an automatic LGT, and when I come to a stop for example a red light or stop light, or if I've been stopped and the light turns green and I just let off the gas to roll into the intersection for a left turn, sometimes (and quite randomly, hard to reproduce so I haven't been able to get a shop to actually see what I mean) the car would shudder or shake, some of the dash lights would come on, the headlights would flicker, and the car would threaten to stall out. If I hit the gas, or hit the brakes, the RPMs catch and bounce back to normal idle RPM, but if I don't do anything it'll eventually stall out. I've changed the battery, checked ATF levels (though I plan on changing the ATF sooner rather than later just in case), and to the best of my ability checked hoses for cracks that might suggest a vacuum leak. Also cleaned the TB maybe 5000km ago, and I cleaned the MAF recently as well. Unfortunately I'm quite useless when it comes to cars, and I haven't attempted to check out the fuel filter, or find a way to check the torque converter, etc. No check engine lights at all, and scanning with my OBD2 tool shows no codes. Anyone have any ideas on how to proceed? I want to take it into a Subaru-specialized shop that a bunch of my friends and local forum members recommend, but I don't know how to tell them or show them the issue since it's so random, and I can go many days without it happening, or it happens multiple times a day! Thank you so much everyone! Edit: if it is the torque converter, how does one "check" if it's good? Also I tried to find the DACCO SU19 stock T.C and everywhere seems to be out of stock, I just put in a notification on RockAuto but even eBay, etc. don't have it. Closest I found was the IPT aftermarket high stall one for a cool $638 This is just a sort of list I've been keeping but it seems very daunting to a noob like me!
