The drain and fill is all you ever have to do. A full flush is not reccomended. I drain and fill at every oil change. Excessive ? Yes. But that is me. It is only $25.00 a year for that piece of mind.

You have the right idea, dcfish. I talked to a Lexus mechanic about flushing the tranny and he said no need for that. He recommended the 2 quart change every 10k miles or so. It may be excessive but, considering the cost of a rebuilt tranny, is money well spent.

It's impractical to drain the trans, because parts like the torque converter retain quite a bit of fluid.

- not like draining engine oil.

so draining out 2 qts, is like diluting the old stuff with fresh.

Doing that often enough, will keep all the fluid in good shape;

avoiding the necessity to flush.

It is not diluting, It is replenishing.

how bout describing it like a blood transfusion -

substituting older blood with low cell count, with fresh new blood with high cell count.

the influx of the substituted blood would raise the overall cell count....

************************

total capacity of a dry trans is 9.4 qt.

a drain and refill, replenishes 1.9 qts.
