I want to put Mobil 1 ATF in the tranny. Mine has the Mag-Hytec pan.

Is it ok to switch without draining the torque converter?

Also how many quarts will it hold?

IMO I would use HOOTS 'method' n flush the convert n cooler........... really easy... just have to remember how much is taken out and how much you got in the pan. Xtra set of hands would be good to start n stop truck for ya.

takes about on hour to flush it, just did mine this weekend. I used a piece of 1.25" clear host to tell when all the Dex III was flushed. most of the time was the old fuid draining. buy the 5 gal pail, you should have enough left over to do the transfer case as well......
