Amsoil seems to be very popular. I used Penzoil Synchromesh in the trans and I don't like it. I'd go Amsoil or Gm when I do it again. I knew at the time because I'd seen a comparison here, but the only thing available locally on short notice was Penzoil and so I stuck it in. Don't do that. ;lol:
For the record, it shifts hard after putting it in. Especially so cold.

i just ordered ACDelco dexron 75W-90 Part#88862624 for the diff and Amsoil TQ Drive for the trans. it'll be about a week or so before i get to it but after days and days of research. Redline D4 ATF and Amsoil TQD seems the be the most popular and positively reviewed for the trans and oem for the diff. FYI do not buy Amsoil through amazon. it's almost twice as much as it is directly with Amsoil.

Changed both over the summer. Research results were same as CZ51 for preferred products. Went with Redline D4 ATF for trans and ACDelco 88862624 for diff. Approx 4K miles since, smooth shifting / driving. Can recommend with confidence.
