#7 of 13 Toyota Landcruiser Transmission noise or whine
Feb 05, 2007 (7:07 pm)
I bought a 2000 LC in July 2006. It was a one owner with all services and well maintained. Lately I have noticed a whining noise when I am accelerating. Originally, the noise only came on when I was travelling at 70mph or faster. As of late it begins to whine around 30mph and continues as I accelerate. All fluids in the Transfer Case and Tranny are fine. The LC rides great and I am having no shifting problems. The dealer says I need a new tranny at the tune of 4k. I cannot justify that cost just yet. Has anyone else had this problem and if so what did you do to fix it? Surely there is a lube out there to cure this noise without replacing the whole transmission? Holler back!

Have you considered a complete transmission flush and replacement with synthetic ATF?
I use Red Line, but other companies make the synthetic ATF. Might be worth a try to see if you get some symptomatic relief of the whine you mention here.

Thanks for the reply. Well everyone I talk to seems to think a transmission flush is a bad idea (at least for a healthy tranny). I have considered synt atf. A friend seems to think Lucas products are the way to go...transmission fluid or trans fixer. any thoughts?

Sorry to just get back on here. Wondering why folks are leary of the tranny flush? Is it the flush or replacement with syn fluid that concerns them?
I have red line in mine (and in TCase and F/R diffs as well)

I'm talking mainly about fluid changes that you DIY at home. As your linked post shows, power flushes can cause some harm--but one caveat is who and where they're done. Not sure of the whole story in your link, but a reasonable assumption to make, might be that a dealer rathe than an indy might know of potential problems relating to power flushes. That's a whole other topic though =)
An easy way to keep things clean (if you're starting out with a new vehicle) is to drian and fill the pan only every other oil change. Also, a cheap "flush" trick is to drain and fill the pan, then loosen the drain plug so that just a trickle of fluid comes out and start the car and add fresh fluid until you see the fluid color coming out of the pan matches the color of new fluid. I drip the fluid on to white paper towels to make sure the fluid coming out matches fresh fluid from the container. This is not a power flush, just a trick to get in a little cleaner fluid.
Again, as noted in your link, you need to know your particular vehicle. I've never had a tranny issue on any of my LCs using this method of fluid "cleaning" and changing.
