The manual that came with your car contains all the information you will need on transmission service. If you don't have a manual, you can download one on the Lexus website. It will answer all your questions.

Lexus's stand on this is the transmission is sealed for life. This doesn't mean you can't service it if you want to, but keep in mind that the filling procedure is a little more involved since there is no dipstick. I would recommend you drop the pan (clean it out) and replace the filter if you plan on going through all the trouble of replacing the fluid. I personally disagree with the lifetime fluid stance on transmissions and plan on changing the fluid and filter in my wife's car around the 60k mark.

I am going to have the dealer change mine at 60k miles.

I spoke with my mechanic at Toyota that has been doing work for me for at least 10 years, no problem hooking up to the WS machine and replace all 12-14 quarts. I want to replace at 60k which is another 4k for me. Doing rear Diff oil at the same time or will do at home, same for the front diff. $189.00 for the trans service. He discussed the proper procedure for checking the trans fluid level.

I haven't looked into the correct way to check the oil level but I'm sure its like other sealed for life transmissions where you wait for the transmission to get to a certain operating temperature in order to determine if its full or not. The only thing that scares me about the using a machine is cross contamination of fluid with the car before. Plus, in my opinion, its a must that the pan be dropped, cleaned, and the filter changed. Would you change the oil in your car without changing the filter?

$189 seems unbelievably cheap especially for Lexus/Toyota branded fluid. He must really like you!

Sorry about posting in both threads .... lol ...thought it was more relevant in this thread


I have studied the procedure and your are correct, certain temp at a certain level, I also believe a jumper is installed at one of the wire junctions that puts the computer into a certain mode to monitor the trans temp as it warms up and when it correct, a light flashes on the dash and do your check at that point, something along those lines. He said he would make sure the machine is clean and purged prior to connecting, again over 10 years with him and have trust.
I had a discussion with him on dropping the pan and such, however, my research finds that on our cars, its a strainer type, so it could be taken out and cleaned or just replaced, I believe the part is around $60.00
I need to get a quote on pan drop. $189.00 covered only the service and included 12 or 14 quarts of Toyota WS fluid.
I don't like these sealed units at all, I am not taking any fluid 100,000 miles :nono :

It would be interesting to know where they sample the ATF temperature? I have a Fluke 52, dual channel, K-type thermal meter that would be perfect for the job.
