Filled w Castrol Dexron VI in 95 BMW 525i-post 2
This is repost. I posted somthing similar is it just seemed to have disapeared.
I just had my independent BMW mechanic, DRAIN fuid and flush my trany oil cooler (with air) after 35,000 miles on the current fill of Mobil 1 Dexron III synthetic atf fluid. Trany is the GM made (in France) automatic 4 speed transmission. Mechanic said the old fluid was very clean did not look burnt or dark.
He then filled with 7 quarts of Castrol Dexron VI which is a synthetic blend. Car runs fine so far. Very smooth and responsive. We will see after a couple of thousand miles.
There has been some concern that you should not use Dexrion VI in older cars that required Dexron II. Valvoline said it was fine to use. Castrol was non-commital yet the bottle and web site stated backward compatible. and my BMW dealer said it was fine.
