Trans Fluid?

Dextron 3.

------------------
Give em' hell!

Personally I use Type F and that's what the local trans guru told me to use. Jeff Harrington uses it in his 9.80's car which runs in OD and has had no problems in over 4 years.

Not to cloud the water, but I would use whatever your trans guy says, if the trans guy is Hydramatic (GM) then I would use what they suggest D3.

On another note, I've been through 3 engine builders in the last 7 years and each one said to use a different motor oil. (Kendall, Redline, Mobil 1) So maybe it's just personal preference.

I use Type F but I think Dexwhatever is okay as well.

I have a deep trans pan that needs about 10 quarts. Should I put in 5 quarts of mobil 1 synthetic and 5 quarts of type F? Or just 10 quarts of type F since its cheaper than the Mobil 1 synthetic($6/qt)?

I would not mix them and I would be sure that the Mobil 1 has worked well in a number of other 200 r4s before I used it.

I have noticed it is getting harder to find name brand Type F's around here and would have no problem with Dexron as I know it works okay, too.

I'll go with Dexron III then. How much do you guys pay for Dexron III per quart regardless of the brand? I saw at Target a Valvoline brand Dexron III for $1.89 which sounds like a reasonable price. What do you think?
