Transmission question!
Car: 1991 LS400, 73000 miles
Hi, Since I've never driven any other LS400's other than the one I bought, I don't know the way certain things are supposed to work. My question is about my tranny, and again, becuase of my lack of knowledge, the tranny may be perfectly normal; but i just want to ask to make sure. So here is the question: When you guys shift from Park into either Reverse or Drive, does the car sort of firmly engage, to an extent that you feel it? or does it engage in a way that you don't even notice you put the car into either R or D? It doesn't really SLAM into gear, nevertheless the car does move JUST a little forward (D), or backward (R), again, it engages firmly. Do you all experince this? or could I be having some tranny problems?
Really appreciate your response

my 95LS engages rather aggressively...especially while the car is warming up and the rpm's are higher. seems like a common thing with LS's across the board. i always make sure i let go of the brake when i put the car in drive so the car lurches forward and moves rather than shaking in its place! try seeing if it does lurch when first turning on the car or after driving for 5 minutes or so when the engine is cold. once my car is warm i can hardly notice changing gears or shifting from R to D.

well, of course if the engine is cold the RPM is higher and so the engagement will be more aggressive. But mine still engages firmly even when the car is completely warmed up. Not as aggressively as when it's cold, but for example, in comparison to my mother's 2000 Camry, it's much more noticable (on the camry, you don't notice anything at all). I had actually thought about the fact that it's a much more powerful engine and so it does produce more torque than a smaller and less powerful engine. Does this sound like a good explanation to you? Also, is there ANYBODY out there who actually does NOT experince this with their first gen. LS400? We'll wait for your response, thanks.

tranny
I dont think you have anything to serious there, I am experiencing the same sort of issue with my 92 ls400 which now has over 130,000 miles on it. so far so good, just keep tabs on any leaks or grinding coming from the tranny, you may need to change the fluid and filter if its been a while.good luck

Letxtreme, I've got to change the tranny fluid soon, maybe in a week or so. I was going to do it anyways, it's been a while since the last one. It might help, but I think it's just normal for the tranny to shift rather firmly. So far, that's what most owners have been saying, so i think it's normal I'll do the tranny fluid change anyway, thanks though.

MIne is a 91 and yes there is a firm engagement.
BUT , if I stop at R and then go to D then the engagement
is MUCH softer.
It's been 36K since the last oil change, does any one
know how to drain the TC w/o a flush machine.
I read many different descriptions. The one I like best
is to drain thru the cooling lines, and let the tranny pump out
the fluid while you add fluid thru the tube.
Avg price of a flush at LEXUS dealer ?

My 93 does the same thing, but I can almost here a metal clank. Only on cold mornings. I have no idea when the fluid has been changes since I just bought the car so I am getting it drained tommorow.
My dealer wants $100 to drain and refill and $150 for a flush. Is the flush worth an extra $50?

IMO you should spend the extra 50.00 and get all the fluid replaced-make sure they use Toyota type 4 fluid and have them drop and clean the pan and screen.I just had that done by a local Lexus dealer at a cost of 200.00.I don't regret it since any tranny work on a lexus is mucho dinero-an ounce of prevention....
