Transmission fluid changes: partial vs full flush??

[EdNerd]

I put the rear tires on ramps and the front on jack stands. That way I could run the engine and let the front wheels spin through the gears. I wasn't sure mine had a drain bolt either - but once I was underneath, the drain bolt was obvious.

You get a skoosh more than 2 quarts out of a single drain. After the first drain, I completely removed the pan to replace the filter - and discovered that removing the drain bolt doesn't drain all the fluid from the pan!! Knowledge that fell from the sky! Fortunately, I was at the other end of the pan at the time. But between the pan incident and the one time the funnel came out of the dipstick tube as I was filling, I have quite the pile of kitty litter in my driveway.

After four drain-and-fill cycles, the fluid is reddish and clear. But I'm not personally satisfied I've got a high-enough percentage of new to old fluid in the mix. So I'll probably run another gallon (two drains) through at a later date. My work schedule won't give me time until August, though, and then it'll be time to change the oil and do my timing belt again.

Cheers!
