Same old story, another new person.

JCL, are you sure our transmissions are sealed? What about that vent tube that runs all the way to the engine bay.

Whatever.

I changed my fluid at 70K miles. Not flush, but drain and fill. I had crap stuck in my solenoids at 80k miles, so that put in about 10q of new oil.

My Lexus GS430 came with a card in the maintenance manual to drain and fill transmission every 30k miles. It is a very rare occurrence for the Lexus trans to fail, but the cases where it does fail, people were clueless about the regular oil refresh it required.

Will I keep changing the oil in my X5. Yes I will. Is it possible it will fail, yes it is. But, in my case, I am not afraid to try. I also use the proper oil, ZF6, and use a computer to monitor the fluid fill temperature.

Is my transmission acting better? Yes it is. But that could be since I "maintained" it with new solenoids, new fluid (times 3), new seals, and removed the crap that was blocking my solenoids since the beginning.
