tofuli Posted April 22, 2007 Share Posted April 22, 2007 Hi everyone, My car has recently just started making noises when I accelerate. My car is a 92 SC300 (automatic transmission), with about 175K miles on it. As I accelerate, the noise appear right before it changes gear. I noticed that the noise is at its loudest around 2250-2500rpm, and then when it switches gear, the noise goes away, but comes back as the rpm goes up and right before it switches gear again. This just started happening about 4 days ago. Does anyone have any idea what's going on with my car? I have a bad feeling that I have to have the transmission replaced..... :cries: If so, does anyone knows how much it'll cost? I hope it's something else, something simpler... I've recently moved to Toronto, Canada, which makes it even harder to get parts for this car... Any help will be greatly appreciated!!! Thanks!!!!

Have you checked your fluid level and make sure it is cherry red in color...? If it is not cherry red you must change it. You should be able to get parts from lexpartsonline.com Good luck!!!

tofuli Posted April 22, 2007 Author Share Posted April 22, 2007 Yes, I've checked the level and the color. The level is good, and the color is good too. I did get my transmission fluid changed at the end of February, right before I drove my car from Florida to Toronto. But I didn't get the filter changed. Could that be the problem? Could it simply be that the filter is bad and is clogged up? Thanks for any inputs! Quote Link to comment Share on other sites More sharing options...
tofuli Posted April 23, 2007 Author Share Posted April 23, 2007 I've just found out that the noise only comes on when the A/C is on. If the A/C is not on, there's no noise when switching gear. But when the A/C is on, there's noise when switching gear. Any clue as to what this is? Quote Link to comment Share on other sites More sharing options...
schott1984 Posted April 23, 2007 Share Posted April 23, 2007 Whoa, I was thinking this earlier, but I figured it pretty unlikely. About two years ago I had a Lebaron that did almost the same thing, at first i thought it was tranny, then I noticed I could get it to do it while pulling the throttle while under the hood, and noticed that it came from the AC compressor. I just unplugged the wires from the compressor because the air didn't work anyway. So that's my guess. Time for a new compressor I would assume. BTW, the sound was a horrible screeching sound.
