Here's my highest temp so far (I have a shift kit, but no cooler), and I don't drive very far....

By the way nice view there out your windshield.
Yes..i like some other things besides GM's... I like a lot of things

I forgot to add, so aren't these really high temps (at least 210+ ish) not still bad for a transmission's lifespan? Or does everyone who wants theirs to last over 150k have to eventually shell out the extra money on a separate cooling system?

Aaalso... would a cooling system flush and maybe even trans cooling line flush/cleaning not help at all either?
