Fabricatorx Posted August 4, 2008 Share Posted August 4, 2008 Mine does that also... started as soon as the weather started baking here in Mesa, AZ. Was planning on flushing the transmission fluid soon with some synthetic, maybe the flush itself will take care of my problems. Quote Link to comment Share on other sites More sharing options...
BIGBADDAD Posted August 6, 2008 Share Posted August 6, 2008 I have this same problem, try this...start the car, and shift from Park to Reverse wait a second, and then to drive, in my car when I do this it doesnt jerk. I just replaced my transmission...thinking this would fix it and it didnt. I dont have a good answer, just wanted to know if it is the same problem. Mark P.S. It could be your motor mounts, or trans mount, I replaced mine but it didnt fix the problem. Try the shifting thing I mentioned up top, if yours still jerks when you go from P to R to D, then it is probably a bad mount. Mark Quote Link to comment Share on other sites More sharing options...
Imzjustplayin Posted August 7, 2008 Share Posted August 7, 2008 I heard that there is something related with this and a ground wire in the trunk. I read about this issue in some FAQ somewhere, possibly on this site; just search for ground, trunk wire, LS400, transmission, shifting, something of the sort. Also don't switch transmission fluids, I read the transmission is really finicky and doesn't like ANYTHING but the transmission fluid from toyota, weird stuff really. Edit: This is what I was talking about:http://us.lexusownersclub.com/forums/index.php?showtopic=34244 http://us.lexusownersclub.com/forums/index...showtopic=50109 http://us.lexusownersclub.com/forums/index...p;hl=trunk+wire http://us.lexusownersclub.com/forums/index...showtopic=50087 There is more on it if you search around.

Blayd Posted August 20, 2008 Share Posted August 20, 2008 Just remember that if it is the transmission the problem will NEVER come and go. Transmission problems do not do that. Quote Link to comment Share on other sites More sharing options...
yoichisoma Posted August 20, 2008 Share Posted August 20, 2008 The throttle cable that tells the trans how hard to shift was broken on my car causing the trans to think it was at a high throttle level and thus shift fast and hard. Have someone check this cable out. Yo Quote Link to comment Share on other sites More sharing options...
