Rick Towers Posted March 24, 2013 Share Posted March 24, 2013 I have a 1996 Subaru Legacy Wagon, EJ22 engine, Auto Transmission. It surges forward after i shut the engine off, this happens after driving for 2 miles or 200 miles, it always does it. Any ideas why this happens?

johnegg Posted March 24, 2013 Share Posted March 24, 2013 you have torque bind. do a search and you will find a ton of info. note: 1/ shift to N and wait before you shift to P to shut it off. 2/ test drive the car in slow tight circles on dry pavement and report back. 3/ put a fuse, any fuse, in the FWD holder under the hood on the passenger side near the fire wall and the wiper motor. problem gone? 4/ all of your tires should be the same brand, tread, size, inflation and wear. they should all be with in 1/4 inch in circumference (not diameter). mis-matched tires can cause binding.

Kennyfvholla Posted March 25, 2013 Share Posted March 25, 2013 I agree that issue is most likely torque bind. And I second every single suggestion John has made. Link to comment Share on other sites More sharing options...
Rick Towers Posted March 25, 2013 Author Share Posted March 25, 2013 Thanks! I will check into everything you said. Can a torque binding problem be the culprit for my subaru to be shuting itself off too at a red light? I also found this info too. http://legacycentral.org/library/torquebind.htm Link to comment Share on other sites More sharing options...

Off Road SHO Posted March 25, 2013 Share Posted March 25, 2013 Yeah, I just went through the whole torque bind ritual on my 96 and after ALL the cussin and kickin, it turned out that John's item #4 was the culprit. Even though all 4 tires were the same size, two were from a different manufacturer. I even did a crude diameter measurement which showed that the tires were the same approximate diameter, but it wasn't until I did a rolling circumference measurement that John noticed that my tires were way off. I swapped the two "smaller" tires to the right side and torque bind is gone. Tom Link to comment Share on other sites More sharing options...
Rick Towers Posted March 26, 2013 Author Share Posted March 26, 2013 Well, i installed the fuse for the FWD, still have the problem. I did notice that all 4 tires are the same size but, the rear passenger tire is not the same brand or tread as the other three. I think i'll get 4 new tires today. The tread is about less than a 1/4" on the two front and i have about a 1/4" tread on the back. Link to comment Share on other sites More sharing options...

Rick Towers Posted March 27, 2013 Author Share Posted March 27, 2013 do you have a red FWD light on the dash when the fuse is in? No, i had no FWD red light on the dash with the fuse in. Link to comment Share on other sites More sharing options...

Rick Towers Posted March 27, 2013 Author Share Posted March 27, 2013 that means your duty c is probably bad. does your AT Temp light flash 16 times at start up.? Where can i buy a "Duty C" cheap one? I don't see them at the auto parts store. Link to comment Share on other sites More sharing options...
Kennyfvholla Posted March 27, 2013 Share Posted March 27, 2013 You need to buy it from the dealer. If I remember correctly, it cost somewhere just a bit north of $100. Sometimes you can find them on eBay cheaper. The duty-C is what controls the center differential clutch. It causes plenty of different binding issues when it fails. It is located in the tail end of the transmission. http://i46.tinypic.com/352rb0l.jpg Link to comment Share on other sites More sharing options...

What do you think?? Link to comment Share on other sites More sharing options...
Kennyfvholla Posted March 28, 2013 Share Posted March 28, 2013 Yeah, that's what most do. I would do it as well. It can't hurt, and if anything, it'll help. Link to comment Share on other sites More sharing options...
Hemingway Posted March 28, 2013 Share Posted March 28, 2013 I agree ... I would replace them while it is apart. Might as well ... if not, you might regret not taking the extra step in making it as good as possible. Link to comment Share on other sites More sharing options...
