I suspect that the anti-freeze in my 92 LS hasn't gotten gunky yet becuase the car's engine water jacket is so well sealed and insulated (well designed, reliable) from any contaminants entering form various sources through which the fluid flows.

I think automatic transmission clutch adjustments went out with the Lexus marque. But factually, my son's 92 AWD Aerostar has 125K and has not had the clutches adjusted...yet.

Willard,

So the tranny flushes and diff changes are all hogwash? Wont they over time break down and cause the bearings to go bad?

jahummer

Well, got my car back from the 60K and man was it worth it!!!!!

I thought it was great before but it now feels like a new car! Transmission is smoother, engine a helluva lot quieter, suspension is tighter, accelerates faster, brakes faster, steers better, etc!

A bargain @ $1200.00!

Erfan

Well i am glad your car is running great. Do you really notice the diffrences?

jahummer

Yes, it's amazing! Like I said, I never noticed anything wrong until I got it back now it feels like a different car (actually as I remember it as new). Was planning on trading it in shortly but now I have to strongly think it over.

wwest

that's how I feel each time I wash and detail my 92 LS, it even feels like its faster, must be all in my mind though, it still has all of the factory fluids except the engine oil.

jahummer

Considering that they changed the plugs, cap, rotors, wires, adjusted the timing, the transmission, injectors, etc. This has nothing to do with it?

Erfan

Jahummer,

What year is your LS400? What octane and brand of Gasoline to do you feed it? and how much is it per gallon?

wwest

They might have "checked" the timing but you can be damnsure they didn't adjust it. There is NO adjustment to your timing, unless someone has figured out how to reprogram the engine ECU.

Oil, oil filter, and air filters, about $50 all told, that's all your car really needed!

Oh, maybe a good wash and vacuum job so you could "feel" the car had been "renewed".

jahummer

Still the car is quieter, quicker on HWY acceleration, shifts better, doesn't lurch when turning A/C on-off, brakes are firm nolonger spongy, no more brake noise, etc.

I know my car better than the dealer, I have several and I can distinguish each's idiosyncrasies.

Always use 93 octane, Texaco sometimes Shell. Price ranges from $1.109-1.319 depending on the station. Our all time high was $1.80 something a year ago.

Oh and it's a '97

jahummer

wwest, I do appreciate your feedback and point of view and frankly do share many of your feelings with regard to having someone muck things up. In fact it happens frequently such as snaps not being replaced, etc.

Anyhow, I never dreamed that the 60K service would bring the car to its original driving condition.

I was ready to trade it in but now I have thinking it over

What year is your car and what is the possibility that you just got, unknowingly, an engine or tranx firmware update? Lexus doesn't always tell people what's happening behind closed doors.

Wife and I will be in Tampa near the end of the month on the way to Daytona 24 hours. There used to be a really good Spanish resturant in St. Pete, is it still there maybe?

Willard

look at the post previous to my previous post. it's a '97

re: restaurant

welcome to Tampa. If you are thinking of Saffron's or Habana Cafe, they are still here and busy as always, if it's another let me know and I'll track it down for you.

Erfan

jahummer,

What you dont know is that the Lexus dealer slipped a P4 processor under the hood and charged you all that money But, seriously, I am glad that the car is running like a champ.

jahummer

actually I am intrigued by Willard's comment regarding firmware upgrade. Anyone know about this and what it does?
