Trans fluid
Want to change the trans fluid and differential fluid. Read somewhere that we should stick with Delco brands for the Z. What's the GM brands and serial numbers? Thanks.

I would look at using Transynd 295... We used it in the Allison transmission in our RV behind a 8.1L Chevrolet. I have talked at length with the engineer the spec'd, tested & certified it. I used in my 83 Monte Carlo SS 350 auto trans and my 2010 Challenger 6 son Tremec 6060. Not cheap $40 a gal.

I use Amsoil severe gear 75w90 for the diff and Redline D4 ATF for the trans.
I found that trans fluid is trial and error. My car didn't like Royal Purple or Amsoil ATF. When I was searching the same question I found you can find posts for every ATF that will say it shifts like butter. There will also be posts for every fluid saying it didn't work. Its a matter of finding what works for your car. At 40 ish dollars a jug it can be an expensive and frustrating part of maintenance.
