Aulthou Posted October 15, 2013 Share Posted October 15, 2013 Hey everyone, Quick question for you all, I recently noticed that the automatic transmission shakes the car when I push the accelerator after a while of not touching. It's not much of a gently 'pick up the power' shake, it's quite a move and causes everything in the car to shift place and bang my head on the headrest. It doesn't happen all the time but I'm pretty sure it happens when the car's shifting from 3rd to 4th. When I'm using the shifter itself in manual mode like going uphill, it makes a similar banging noise and feels like something just hit under my feet, again when shifting from 3rd to 4th. I know most of you'd say its normal because of the huge difference in gear ratios and sudden shift of the power. Believe me its not. Has anyone every experienced something like this before? I was thinking of chaning the gearbox oil again but it hasn't been 10k km since the last time it was changed. Thanks! Quote Link to comment Share on other sites More sharing options...
AdventureSubaru Posted October 15, 2013 Share Posted October 15, 2013 Check your drive shaft. If it's a metallic clank noise, you've probably got a bad joint. Could be a loose hanger... worn out tranny mounts. Have you climbed under the car to inspect these things? Without hearing and feeling it myself, this is my best suggestion of what may be going on.

johnceggleston Posted October 16, 2013 Share Posted October 16, 2013 or maybe a bad rear trans mount? Quote Link to comment Share on other sites More sharing options...
Aulthou Posted October 17, 2013 Author Share Posted October 17, 2013 Thanks for the advice guys, I'll find a way to lift the car securely to have a look underneath and let you know=) Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted October 18, 2013 Share Posted October 18, 2013 (edited) Has the automatic transmission fluid been changed within the last 30,000 miles?? If not, suggest changing the tranny fluid 3 times, as well as the external tranny filter. I say 3 times, as only about half the tranny can be drained at one time. The remainder stays in the torque converter, and won't drain out. Changing 3 times with short drives between changes does a good job of adding fresh ATF. A change of fluid could very well fix your problem. Edited October 18, 2013 by Rooster2 Quote Link to comment Share on other sites More sharing options...
