Whats the best make of transmission fluid..what would you go with im thinking castrol? not coastal

 

I like Valvoline Maxlife. It has worked great for me in all my cars.

 

+1 on the V.M.

 

I'm happy with Royal Purple.

 

+1 for royal purple the pricey purple fluid

 

Royal Purple here, use it in Everything from my WS6, Bike, Grand Cherokee, 89 Turbo Grand Prix.

I even use the Engine oil and Diff fluid also. Hell I even use the Water Wetter in the rad on my bike!

 

ive been using the castrol and it works fine.

 

i just picked up some castrol..the trans builder told me to use mercon V..But isnt that for Ford vehicles

 

DEX/MERC is recommended for most GM, Ford, Toyota and honda. It should tell you on the bottle.

 

it was sayin it was for fords. mercon 6 is for GM's i guess..5 is for fords??? idk im confused

 

You can use it if it is Mercon V.

 

GM is Dextron.

 

If you have been running DIII I would recomend you stick with it. The later versions contain some synthetic and are more slippery. When I swapped mine out I immediately felt softer shifts from the new formula. 49K on car and tranny at the time. If your a new car with it from the factory or run it from day one in a rebuild I would think the new is better. I don't recommend swapping over though.

 

so i can use mercon V?? LOL

 

The tranny was just re-done..thats what the builder said to use in it....

 

Yes!! but why not just get the DEXTRON-3?

 

yuo can use mercon 5 but it's moer expensive I believe. mercon 3 should work just fine. "ATF" is ford's fluid i believe

 

Mercon V is the newer specification for Mercon - Ford has been using Mercon V
in their vehicles for 8+ years.

You should be using a Dexron III. I've had both my tranny (FLT) and T.C (Yank)
folks tell me to use Dexron III. GM began factory-filling Dexron VI in April 2005.

 

ATF=Automatic Transmission Fluid.

 

thats what he told me to use so thats what i bought.. i just wanted to make sure i dont wanna have trans problems again..should i return it for the DEXTRON 3?
