#310 of 2081 LS 400 Shudder
Jul 06, 2001 (11:40 pm)
alan_s that is exactly the shuddering/rumbling that I have with my LS 400, though I notice it at between 2000-3000 rpm, the speed at that rpm is probably around 50-55 mph. Anyway, I am going to get a full chemical flush of the transmission, and refilled with the newer Lexus Type IV fluid next week, and I'll tell you if that helps at all. There have been posts on this board about shudder in the tranny, and they said that the new type of fluid fixed the problem so I figured that I would give it a shot. Well, glad to hear that I am not being paranoid about little problems that may not actually be there.
#311 of 2081 My 94LS400 Clicking noise and Trans. Shudder.
Jul 08, 2001 (4:50 am)
I have a 94 LS400 with around 120,000 miles on it. I am not sure whether the previous owner as done any major tume up on the vehicle. I personaly feel that its about time to do a major tune up. The Transmission is shuddering... like some people have posted before... at 40-45mph and 50-55mph... so I will do the same as they did... Trans. Fluid flush... hopefully it will iron out the problem ... I did not recieve a keyless remote key... aparently it will cost me 330 bucks... My passenger side sun visor is broken.. And my engine makes some clicking noise when after 2000rpm. First I thought that it was my valves clicking... due to dirt or sticky gunk. Then I thought that it could be time to change my water pump... so If any of you have some advice it will be appreciated... THANKS... OVer All THIS IS A GREAT CAR... !!!
#312 of 2081 MPG Drop...
Jul 08, 2001 (4:54 am)
I am feeling an increase in my LS400'94's fuel consumption. According to my research... the car is suppose to do 24-18. But I feel that the consumption is much higher. Could it be that the spark plugs need changed? Please help me out?
Thinking about getting the BOSCH Platinum +4's are those good for the LS400?
#314 of 2081 Re: Message 302, Front Strut upper plates. Also need a 6 CD magazine.
Jul 08, 2001 (12:03 pm)
If you are going to have front struts replaced, by all means have them check the upper plates. If the plates are bad (worn out) then you will have to pay for the labor you paid for the struts to have the plates replaced. The plates are not cheap. (I think I paid 95.00 each). Good luck. While I am at it, I need a SIX CD magazine/cartridge for a '94 LS 400. Contact me at lexoratt.net if you can help me out. The previous owner took the damn magazine with him. (the idiot).

These are made by Pioneer and you can get them from a car audio shop for about $25 if you don't want to pay your local Lexus dealer.

#317 of 2081 97 LS 400 rocks into drive or reverse
Jul 11, 2001 (6:29 pm)
My 97 LS400, 30k miles, rocks when I shift into drive and reverse. The whole car moves. I spoke to the service manager at Ray Catena Lexus in NJ and he said every 1997 LS400 does this and offered to let me try other used ones. The car drives great in every other way. This sounds like bull to me. I never had another car do this except my 93 Honda Accord. Is this true? Thanks
#318 of 2081 LS 400 Shudder
Jul 15, 2001 (6:57 pm)
Well, I got the transmission fluid flushed ($200, ouch I'm still in college), but it did not fix the problem that I had with the rumbling at 2200 RPM. The T3 shop said that it might be the transmission mounts, or the torque converter, but when they checked for the shudder, they could not find anything. I think that it may be resonance in the exhaust chamber, and that I can deal with the sound as long as it is not problematic. Anyway, if anyone else has any luck with this annoyance, post what you find.
#319 of 2081 LS400 Shudder - Tires?
Jul 16, 2001 (7:23 am)
I started suspecting that the noise and vibration may be tire related. I had Michelin MXV4's which were brand new when I bought the CPO LS400 3 months ago. The dealer and NTB said that the symptoms did not suggest a tire problem. I rotated front to back. The noise and vibration became worse. Then I put my spare on one of the rear wheels which is a Bridgestone Turanza. The noise and vibration reduced considerably. On Saturday, I went back to the dealer and they replaced the MXV4's with Bridgstone Turanza Revo Z's. The problem is *almost* gone... not quite but VERY VERY much improved.
Perhaps you may want to look at your tires as a possible cause, even though it seemed highly unlikely to me that my problem was tire related.
Please let me know how you make out and what tires you have.
