Hi everyone. I'm a new owner of a used GX470. Picked it up a week ago. Its a 2007 in silver and has 58k on it. Just took it to the dealer and got the "clunk" fixed at no charge. Is there any other TSBs I can bring it in for? Only other thing i noticed was when it was dry out the rear had a very very very annoying squeak/rattle thingy going on. But it rained and its gone. Mystery. Anyway my question is did anyone have any success with doing a drain and refill on the transmission?? I cant figure it out. Im all searched out so please help. Also here is a list of what i did so far. Let me know if i missed anything.

Engine oil and filter drained and replaced with Mobil 1 synthetic and Fram filter
Fram engine air filter
New cabin air filter
Front rear and transfercase all drained and filled with Mobil 1 synthetic gear oil 75-90
AM I MISSING ANYTHING??
THANKS!

 

I probably shouldn't post this, but just had to...even though the vehicle is Japanese, we still pronounce it with an "L", not an "R".

 

that has a lifetime "world standard" fluid...but if you must there is a drain and a fill at the lower right rear of the unit...make sure you measure the amount drained and have a handheld pump ready to refill with new fluid...btw it only drains about 3 to 4 quarts max at a time.
