Again if you think the manufacturer of your vehicle is lying to you and goal is to destroy your transmission would sell it today and never buy another. Lets see sixth Lexus over 700,000 total miles and never changed and guess what never had a problem. But you change the heck out of yours. Post your transmission experience.

A guy on YouTube had driven his Tundra hauling heavy construction equipment 1.5 million miles. When asked about his transmission said I never changed it and had to replace it at 750,000 miles. If mine last to 749,000 miles I am okay with that.

So if you read before you typed I said go ask - "Ask the Tech's" "and the Master Tech'". Not a service Manager. The NX has already had some Transmission fail Recalls. The Service Manager is not going to touch a Trans that unbeknownst to them could potentially already have a problem then own the problem after a Trans fluid service going against what Lexus says.

Does the Trans have a drain plug and a fill plug? Does it have bolts to remove the Pan and a replaceable Filter? Think about why it may?

Regarding your 1 Tundra Guy Towing. The Factory Toyota Service Manuel said for the Tundra - Towing " Toyota recommends inspecting the condition of the automatic transmission fluid every 30,000 miles, and replacing the fluid at the first sign of contamination., color, sedimate, discoloration, or unusable odor". So following the Factory service is correct thing to do, or not? Based on your statements? Can't have it both ways?

So one You Tube Guy claims what you posted. How many Tundra's you think that Tow have actually had Trans fails, none? The CL Forum has varied opinions, and experience on this all the time. It's your Vehicle to make a choice. It's also othesr opinion to post theirs. It's ok so Relax.

Is this your Transmission?

You asked me to "Post your transmission experience" , so here you go. Lexus claims Lifetime for my GS350 Trans also. Yet they have this in my Service Display . Asian who actually built my Trans builds my Trans also said this. Again not telling anyone what to do, but new fresh non contaminated Fluids hurt no more that changing your oil.

Service unnecessary?

To all the naysayers shooting me down on this thread and wanna believe it's not necessary to Service your transmission, Good luck!
YOU are exactly the reason why I only buy new vehicles.

I always remember the tv commercials for fram oil filters

This mechanic basically nails it! He explains all the caveats and benefits for fluid flushing / changing in a car.
