Transmission fluid vs change

Postby 2007Vibe » Tue Feb 13, 2018 4:40 am

Good day everyone,

I have a 2007 Vibe with Auto transmission, have had no issues in 82,000 miles. In checking the transmission fluid, it has become brown in color instead of red. I need to know is it best to spend 125 to 150 for a flush or would a change of fluid and filter be best? I understand that only 3 quarts of fluid out of 7 or 8 quarts are removed when performing a fluid and filter change. I am certain I can perform the fluid and filter change and change it every 30,0000 miles, until virtually all has been replaced,but it seems in the long run a flush would be better. All remarks would greatly be appreciated.

Thank you,

I just bought my Vibe with 150K miles on it with no service records. One of the first things I did was to change the AT fluid. I dropped the pan, changed the filter and cleaned the magnets. I had never done this before and it was simple and clean enough thanks to YouTube. I got the fluid on sale for $5/qt and the gasket and filter was less than $15. I will drain and fill again soon, maybe twice in the coming months, to "thin out" the remaining old fluid. There was no obvious problem with the fluid or the shifting, so I feel confident this will work well enough to get enough fresh oil in there.

At $5/qt and with the convenience of the drain plug on this car, I'd rather do this than take it somewhere for a flush. If a shop does a flush without removing the sump pan, I hear there's a risk of circulating debris. But I'm no expert at this, just going by rumor.
