1992 Lexus sc400 has very high rpms in low gears

Recommended Posts

Hello, I had bought my Sc400 around 4 months ago. It was bought at 96k miles and now has 99k. Recently when i floor it after being at a stop light my car will reach almost 7k rpms before switching to second gear and will only switch gears if i take my foot off the gas. I sometimes even try to put it in second gear manually but it wont switch gears till i stop accelerating. And even my second gear will get up 6k rpms before switching to third. But my third gear hardly gets over 4rpms. I just dont think this is normal and was wondering if others were having the same issue?

      Hello everyone, this is my first time posting on a forum. I am wondering if anybody has done tt supra front calipers on the front, and moved the stock sc400 front calipers to the rear. My rear caliper seized up and I was looking at buying remanufactured tt supra calipers all around, but the rear calipers are absurdly high in price for some reason no matter where I look. So I started looking at different caliper options, ls400, supra, remanufactured sc, etc. But maybe this could be a new setup unless somebody else has already thought of this before (which I have a feeling somebody did). Thanks for the help in advance.

      I’ve read that on SC400 the power steering can leak into the intake causing the smoke. And the reason this is happening is the idle air control value is faulty. Is this correct?
