Hot Running Trans Temp - Ideas?
I have a 2003 Chevy Silverado 2500hd, 6.0l gas and the 4l80e trans. For the last 15 or so years it's had a 16 pass stacked plate trans cooler with a fan on it to keep the temps in check. about 1...

I'll be the in-radiator Trans Cooler isn't a stacked plate design.
External is mounted up in front of the AC and Radiator with a push design electric fan. 16 pass stacked plate design (Derale I believe is the manufacturer).
I've had the in-radiator transcooler as part of the circuit and removed it to see a difference.
Trans has always run hotter when doing long sustained hill climbs out of OD - but never to this level (about 220).
The Water temp inside the radiator never budges above 190 - even on sustained hill climbs - which is great, but if the internal Trans Cooler isn't as efficient as the OEM, then that's where my problem lies (Water to Oil is more efficient at removing heat than Air to Oil)
I think my next steps are to reconnect the Internal Trans cooler, check the volume coming out (it should be the same) and contact the seller of the Radiator to see if the internal is stacked plate like the OEM version.
thanks to all for your advice and guidance. I really appreciate all your insight!
