I have a question on trans temp steady state.. I just got my 79 RC pretty much done last night. I drove it for a few hundred miles prior to tearing it apart for paint/body 2 years ago. I had the trans rebuilt professionally before then, and didn't see anything abnormal afterwards. Now after putting it back together, I'm running down the freeway at 70 on my way to PowerTour, and the trans temp is about 200F. I have an external cooler, as well as the radiator one.

Is that temp normal? In my dads GTX with an external cooler, we rarely saw 180, and only when we were working it pretty hard. Truck has 35s with 3.55 gears if that matters. 360 with mild cam and aluminum heads, stock replacement converter done when the trans was.

What do you think? We thrashed the last two months to get this thing done for this trip, so if you have any ideas on things to check let me know. We are on our way from Detroit to Madison WI right now, and hoping it doesn't climb any higher. Thanks!
