Rx300 Transmission Filter

Hank the tank · March 13, 2013

Hi. Have a 2000 rx300 with high pitched whine in synch with the revs. Gears not slipping and level is fine. Long story short need to get transmission filter kit to do what lexus garage won't, and drain the tranny. (They just want to replace the whole tranny)

Now 2 questions. Where in uk can I get a kit? And why do some of the kits ( us sites) have 17 holes and some 18 holes. Am confused.

Hi Hank,

why wont Lexus do you a drain and change?

Lexus Sheffield did a drain and change on my 2001 RX for £50.

Cheers Jason

Hi Jason.

They just said no as the fluid should be good for life. They even denied there is a filter in the pan for the fluid. Then they suggested if I can't afford a new gearbox just drive it till it dies. Not impressed with their lack inclination to help.

According to the database the part is called a "Strainer Assy,Valve Body Oil"

Part numbers 35330-06010 for 11/2000 0n and 35330-0W010 for 07/2000-10/2000 models.

Priced around £70.00.

Just checking do I need to replace this or is it just a pan without a filter and i would need just the gasket oil strainer (35339) instead. Plus the gasket (35681A) along with the oil?

Hi Hank,

Im pretty sure there is a known weakness with this gearbox ( think I read it on US Lexus forum) , and from what I recall they advised changing the gearbox oil every 50k, this is why I had mine done, no other reason, as my gearbox is fine!

BUT, since talking to a mate of my brothers who runs a Auto gearbox repair shop, who said to me quote" if people changed there auto gearbox oil regularly I would nt have enough work to earn a living wage"

Also if you watch programmes like Wheeler Dealers, Ed China always changes the Auto Gearbox Oil as soon as he gets an auto in! I remember a Jag on there that wasnt shifting well, a new filter and oil change sorted it!

I would ring Lexus UK help line, they really should nt be able to refuse a perfectly reasonable request as you have made.

Cheers Jason
