Does anyone with an aftermarket trans cooler still have the stalling issue, I put a truecool 40k on my 05 and my 08 and neither have stalled since

2005 xl denali with the 6.0 and a 2008 escalade esv with the 6.2, both awd...before in stop and go traffic 90 degree day not towing trans temps would creep up to about 250 degrees on my 05, with the new cooler it hasn’t gone over 200 degrees regardless 110 deg day pulling a grade towing my boat...
The issue is caused by vapor lock, there are 2 extreme heat sources in the area of the fuel lines, the catalytic converters and the heat from the transmission, although I couldn’t do anything about the cats however i did reduce trans temps significantly, not knowing if it would solve the...
