I drain my tranny fluid that I just filled it up 30 minutes ago and it color pink. Is it supposed to be red since thats the ATF color?

if it is pink and not clear or see through then it has been aerated (probably due to being run with not enough oil) or it may have been mixed with water (engine oil goes a lighter colour when water gets into it)

Which is most likley?

Yah its too runny too. It seems like it is mixed with water but where the water came from? I will flush it agsin and refill to see if it can push out from hose going to the radiator...

The transmission fluid is run through a line that passes through the radiator internally to cool the transmission fluid. It's possible there's an internal leak, and coolant is getting into the transmission fluid. Is your coolant level OK?... does it get low and need to be topped off periodically?

Actually i got new radiator....

Take the cap off the radiator and look there too. If the cooler inside the radiator is broken or cracked you will see trans oil in the radiator fluid too. They will mix with each other.

The transmission fluid is supposed to be pink/reddish in color. Perfectly normal. No need to do anything.

Yah scott its not supposed to be too runny I think....i will flush the fluid tonite and get the return hose to a bucket and pour the fluid on the dip stick till i get the color. If I wont come out with that color red then am convinse its ok.

Transmission fluid is, "runny", or very thin in viscosity. It's normal. A pink/reddish color is normal. For best performance and protection, use a synthetic ATF.

I assumed (probably a silly thing to do) deejayphilo that you were saying that the fluid came out a lighter pink colour than what you put in - since you just drained & refilled it

or

did you manage to refill the system without seeing the colour of the fluid?

Nope drain and drop the whole pan. Clean the pan..put new filter and gasket. Filled with the tranny fluid. I still think something is wrong on the tranny it doesn't right. It rans good though which is the best part.
