A couple of days ago I posted a thread asking for input on changing the AT fluid http://www.fjcruiserforums.com/forum...e-fluid-2.html
. As I mentioned in my post I have 55K on the FJ and decided to change the AT Fluid.
Today I arrived at my friendly Toyota Dealership with whom I have a great relationship. Once again they tried to talk me out of the process again claiming this was "world standard" AT fluid and that it didn't need changing until 100,000 miles. I told them I decided to change it anyway. I discussed what they were going to do. At first they were just going to drain the pan and refill. I insisted that they do a total flush which takes almost 16 quarts of AT WS fluid at $7.00 a quart... Ouch!
As many of you know the transmission is a sealed unit and they have to pump the fluid in and out and there are several steps that need to be taken to ensure the fluid has been properly refilled. The process takes approximately one hour. However, because I'd been driving my FJ instead of leaving it at the shop overnight I had to wait over two hours until the transmission cooled off enough to get a correct reading. The mechanic told me the transmission temperature had to be below 117 degrees to properly check it.
Once the AT fluid was changed the transmission seemed to shift better and with less resistance. Of course, after shelling out $220. it may have been my mind trying to justify the expenditure...
Below are some pics of the AT fluids.

Bottom line is that I was justified in changing the AT fluid. I wheel the FJ, but I do not push it too hard.
Based on my findings I recommend changing the AT fluid in your FJ at 50,000 miles or sooner if driven in harsh conditions. Sealed system, world standard fluid or not, it may need changing!
We all know that heat and friction are the worst enemies of an AT. My next step is to add an additional transmission cooler. I will be posting my install tomorrow.
