I have a 2002 Century. 200,000 miles.
About 6 months ago I did a pan drop and filter on the transmission. It originally had Dexron 3 in it.
When I did the refill, I used Dexron 6. We are going to replace the car in about 6 months.
It needs a pint of ATF. Is it OK to top it off with Dexron 3, since we are not going to keep the car that much longer?
