May 26, 201411 yr 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!
May 26, 201411 yr 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...
May 26, 201411 yr Author Nope, no lights whatsoever. If it helps, as soon as the car does get up to speed it performs normally.
June 20, 201411 yr 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.
June 20, 201411 yr Author 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.
June 20, 201411 yr 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.
