I have a 2006 GX470 I am experiencing an abnormal knocking noise everytime i operate my sunroof wether its tilting or opening the sliding roof just after it stops after operation. The noise is coming from the headliner besides the maplight. Anybody experience this kind of problem? A step by step procedure on how to remove the headliner would be helpful. Thanks.

Go to the dealer and tell there is a TSB to this issue, and take this copy attached and have it fixed.

Thanks for the info i appreciate it man!

AWD?

My car is a 2WD.

Recently, I hear a slight whinning noise coming from my transmission at low speed from 25 mph to 40 mph. So I decided to change the automatic transmission fluid myself which I bought from my Lexus Dealer , but unfortunately the noise is still there. I have 82,500 miles on my RX already. Any ideas on what is really the problem? Thanks in advance!

Here's the complete service manual procedure. If the ATF was at the proper check temperature, there shouldn't have been spillage from the overflow tube. Sure was easier when dip sticks were standard equipment.

Thank you guys for the inputs! I will definitely look at this matter again.

Recently, I had my transmission fluid changed on my 06 GX 470 from my Lexus Dealer, I noticed that the transmission shifting is not smooth from 1st to 2nd , 2nd to 3rd and so i decided to check the transmission fluid level myself, to my surprised the transmission fluid came out right away when i loosened the 5mm allen check plug on the transmission. I drove my car to fully warmed up the transmission and the car is at idling when i did the procedure. Did my dealer overfilled my transmission and what is the correct way to check the fluid level.

I followed your instruction tightened gas cap and the hose clamp from the fuel tank that connects to the charcoal canister and it works so far so good after a road test.Thank you very much!

Nothing serious,

P0456

After cold engine start.

After VSV for EVAP operation, the VSV for EVAP is turned off

sealing the vacuum in the system and the ECM begins to monitor

the pressure increase.

Some increase is normal. A very rapid, sharp increase in pressure

indicates a leak in the EVAP system and sets the DTC

P0442.

This monitoring method is also able to distinguish what is

called the small leak detection.(DTC P0456)

A pressure rise just above normal indicates a very small hole.

Fuel tank cap incorrectly installed

Fuel tank cap cracked or damaged

Hose or tube cracked, hole, damaged or loose seal ((3) or (9)

Vacuum hose cracked, holed, blocked, damaged or disconnected

((1), (2), (4), (5), (6), (7), (8), (10)and (11) in Fig. 1)

Fuel tank cracked, holed or damaged

Charcoal canister cracked, holed or damaged

Open or short in vapor pressure sensor circuit

VSV for CCV

VSV for EVAP

VSV for pressure switching valve

Vapor pressure sensor

Fuel tank over fill check valve cracked or damaged.

What you should do is

Check your Gas Tank Cap,probably it would be loose while you did last re-fueling.

Next go below your car, there is hose from the Fuel Tank which connects the VSV canister, check out the hose clamp and have them re-tightened.

Now Disconnect the battery terminal (-) and EFI fuse, to erase the DTC code in the ECM memory. And have them reconnected.

That it you are good to go.

Thanks! I will keep you updated.

This morning when i started my 2006 GX Check engine light stays on also the VSC TRAC and VSC OFF. I pulled out the code and it reads P0456 anybody who experienced this kind of problem?

Hi there!

Can anybody have a factory procedure or somebody who did this already on how to change the transmission oil on my 2006 GX. Mine does not have a dipstick and i believe it

uses the WS Type ATF Fluid.
