Synthetic transmission fluid...recommendations?
About to fill my new 2004R. Builder says either Dexron/Mercon or synthetic, both are OK. I'm leaning towards synthetic...
Any recommendations?
Thanks!

I asked my builder that same question when I picked up my 400. He told me for a street-driven car use Dextron. GM has used it in millions of transmissions with good luck. Spend the extra money somewhere else.

IMHO, the best synthetic juice for a GM auto tranny is from Allison-- $38.00/gallon. If you're stuck on synthetics.
A larger pan and a good cooler are the key to a long and happy life.
