As I said, the trans oil is not contaminated by blow by or contaminates like engine oil is. Do you sometimes hear a humming or whining sound when you operate your vehicle? I have had it with Lexus service from Lexus of Roseville California. It has 170K miles, so I guess it did last a bit longer than some of the others I read on the blog. I just did this job this p. I will keep everyone posted.
My wife and kids ride these vehicles. They replaced it but I had to pay for labor. In either case, it's a far cry from your owners manual which basically tells you to just check the fluid level and add when necessary. They put in new parts except for remanufactured casing. Mostly local and freeway driving in So Cal. I'm a mother of three and use the car primarily to transport children and the family dog to various places--I. This is the 2nd transmission replacement on this vehicle.
I was denied any compensation on my issue and was told that Lexus had no knowledge of the problem. The car needed a new transmission by 140,000 miles. I like your idea of comparing samples of the changed fluid at various intervals to determine whether there will be a significant color change. The moral of the story? The new fluid just mixes in with the dirty fluid, so your fluid just keeps getting dirtier and dirtier. I just changed my 2002 rx300 awd with 35k atf. If your goal is to minimize the risk of transmission failure then drain and refill the transmission oil pan every 15,000 miles. Lexus and Toyota dealers only do a drain and fill which is useless.
The dealer only replaces the transmission, there is no attempt at repair. He took the pan off and said there was a lot of metal. I was delayed in efforts because of holiday. The manufacturer and dealer were not notified because the repair cost would be too expensive. I basically never send a vehicle to the shop 'cuz I do most everything myself and then unload 'em as they hit 5 years.
The reason your transmission fluid looks dark is because you've just been having a portion of the fluid drained out and new fluid added. That makes about as much sense as the Iraq War. It is disturbing to me that when I took it to the transmission repair facility they told me that the transmission was flawed in its engineering design and that no oil was able to reach the vital components and that over time they dried out and became brittle. Any qualified mechanic will tell you that the drain and fill performed by Lexus and Toyota is useless and a waste of money. Replacing the knock sensors may work, which makes it important for you to have the vehicle diagnosed right away. I have contacted Lexus for replacement, however there seems to be a need for a recall on this matter.
I have a tough time believing that! He has had it and had to break it down. It was then flat bedded to a mechanic and I am currently being quoted several thousands of dollars to have the transmission rebuilt. Use a catch pan with a wide opening - when this fluid is warm about an hour after driving it gushes out of the drain hole for about 2 minutes. I think looking at all the problems with transmission Lexus should help defray the costs. For instance, you may notice that as you drive your car, it tends to refuse to go into the right gear.
Skip the dollars part, kick your kids out of the garage and do the screen and pan if you are anal about filtration. My 02' Rx300 is at 35000km right now. The biggest variable is probably all-wheel drive vs. Lexus was purchased new and has received all dealer's recommended service at same dealership except the last few, which were performed at another Lexus dealership. I placed some new fluid in a vial, and some of the used in another.
Now I am told by Lexus speacialist 800-255-3987 they only want to pay for half of parts and was told it just failed we don't know why and they refuse to investigate again unless I want to pay for labor. Keep in mind that the automatic transmission fluid serves as the most important component of the transmission since it cleans, conditions and lubricates any seals while serving as hydraulic fluid. Very glad that I changed it. Therefore I drained and added fluid for the first time. I am told it is some kind of seal that is found on upscale cars. Everything in car care comes down to a matter of risk. I paid for my service but.
