What kind of fluid you all used in the trans? And how many qt?

Since the weather is cooler now, first few shifts were very notchy. Want to change te fluid

Amsoil atf, fill capacity is on their website and it's been a while. These cars don't like the cold and shifting will feel notchy until you get it up to operating temps.

Amsoil sythetic ATF-the red top stuff. I used 4 qts but that's because I used a machine to pump it up in there and I think it took about .2 qts to get into the system. Its great stuff though! So smooth!

Thanks for all recommendation. I am more of royal purple or mobile 1 kind of guy. I know redline and amsoil all are good stuff and it's pretty much boil down to personal preference.
