currently have a ATS tranny installed and need to change the fluid.

what should i go with?

 

Only use ATF +4 fluid. I tried running Dextron 3 and tranny shifted like crap. I now put some Amsoil ATF +4 in it and it seems to shift a little bit later and firmer but I dont mind.

 

are you saying to stick with the stuff they sell at autozone or go with something better like amsoil?

 

Go with Valvoline at the minimum. Or if you can afford it, go with Amsoil.

 

order the amsoil online or get it local?

 

Local if you got a supplier near by. Or if you can wait a few days, Heath can get ya some coming. He's the supplier for this site.

 

ATS said my setup holds between 24~25 quarts of fluid.

assuming this number is for a completely new/empty system.

any suggestions on how many quarts or gallons i should purchase?

 

I would ask them since its under their warranty. If it messes up running something they don't approve of they may decide to ditch your warranty.

 

If they put a double deep pan on it will take about nine quarts to refill after a drain, assuming you don't empty the TQ converter. I like to loose the valvebody and let the converter drain so it'll take closer to 20+ quarts, depending on how much stays residual in the lines, cooler, etc.

 

from ATS:

The entire system holds 24-25 quarts. You can use any brand as long as it meets at least Dexron III standards.

how do you access the valve body?
