Dexron/Mercon interchangeable?
is it true Mercon V is the same thing as Dexron except synthetic, therefore it can be used in our trannys?
i heard u can use Mercon in place of Dexron but not the other way around. true?
if not then what is the real difference between the 2 fluids?

Mercon is the fNord equivalent of GM Dextron. Either is suitable for your transmission. The newer formulations have more additives and some are partial synthetic blends like Chrysler ATF+ III which also has an aditive for converter clutch chatter reduction. I use ATF+ III in my 700R4s.

so they are pretty much interchangeable. cuz at my shop i always make sure i know what fluid a car takes b4 i do a flush. especially with the imports. dont some of those use stuff besides Mercon/Dextron/ATF + 3? im using Mercon V on mine right now. u using the additive with ur ATF too?
what do u think of Amsoil full synthetic ATF? i was thinking of switching to that. my current tranny i just recently put it in but its from a bird with 150k + miles. it now has a shift kit and works great. but summer's coming and am a lil concerned with the high temps.
