Transmission Fluid Change Question?

The previous automatic trany flush that I had done at 60,000 miles made a positive difference in shift patterns. I'm now nearing my next 30,000 mile interval. The color isn't bad and it doesn't smell bad either. What is your opinion on just a drain and change vs. a flush at a service center? Please let me know. Also, is it just a good ATF to refill?

Thanks in Advance,

I always do the required maintenance regardless of how the fluid looks

i have always "heard" that flushing does nothing. however in your case it did... i have always just drained pan and refilled. once in awhile replace the filter in the trans.

if a customer came into my dealer with your truck and miles, i would recommend a drain and fill only. Reason being, when the miles get a little higher, flushing can invite seal leaks and that can be a bad deal. that is my 2 pennies..

Awesome advice! Glad to read your responses. I had heard that higher mileage tranny's can act up after a flush. When I had mine flushed at around 60,000 miles it became a little more responsive when it would downshift going up a hill or mountain pass and it would upshift quicker when demand had been met. But, the could have been just because it had fresh fluid and filter. I will just drain and fill this time. Would rather do that than risk leaks or damage.

Thanks again,

I did a tranny fluid and filter change in a car with 140k miles. No real issues with the tranny after it was done (no signs of it going ad beforehand either though). It does seem to downshift better than before and overall the proformance seems better.
