How is your Buick doing w ATF?
I just acquired an 07 Impala and used Lubegard PS fluid this time, little salty per qt at $15 when I can get a gal of ATF for $20. I am probably going to use Valvoline MV Import syn ATF as that is what I am using in my 93 C1500 and was trying to simplify my shelf.
Thanks
