thefish383 Posted May 26, 2014 Share Posted May 26, 2014 Hello All. I recently purchased a 1998 Subaru Legacy GT Limited at 180k miles. Car runs great, except for one small (hopefully) problem. Sometimes, when I step on the gas from a dead stop, I can put my foot all the way to the floor and the RPMs stay low (2 to 2.5k), and the car doesn't get up to speed. Eventually, it catches up and takes off like normal. We (my grandfather and I) suspect it to be the TCM perhaps, because it doesn't do that when I drop the shifter into 1st gear manually and take off from a dead stop. The RPMs then go up like they are supposed to. It's a bit frustrating, but hopefully we can get it resolved with your help. My grandfather is more of a mechanic (he used to race, as well) , so don't worry about dumbing anything down. If you would like anymore info, just ask. And I'm excited to be a part of this forum. You guys have already helped with multiple other small fixes regarding the same car. Great place! Thanks! Quote Link to comment Share on other sites More sharing options...
lmdew Posted May 26, 2014 Share Posted May 26, 2014 Is the AT light flashing 16 times after you start the car? If so you have a trans fault. The TCM hardly ever fail more likely an input. Throttle position sensor... Quote Link to comment Share on other sites More sharing options...
thefish383 Posted May 26, 2014 Author Share Posted May 26, 2014 Nope, no lights whatsoever. If it helps, as soon as the car does get up to speed it performs normally. Quote Link to comment Share on other sites More sharing options...
mzop Posted June 20, 2014 Share Posted June 20, 2014 Ever figure this out, I have same problem, cleaned iacv and throttle body, helped a little, I also have a p0303 code showing for cylinder 3 misfire which I suspect is causing problem.

thefish383 Posted June 20, 2014 Author Share Posted June 20, 2014 Nah, I never figured it out unfortunately. Now the car is just revving really high through first gear, but normalizes as soon as it shifts into second. Warming the car up before shifting into drive seems to help a great deal.

Justcarolynn Posted June 20, 2014 Share Posted June 20, 2014 That's what mine is doing (revving high) from what I'm reading and input from others it's a plugged transmission filter or transmission coolant line. Quote Link to comment Share on other sites More sharing options...
