My truck is a 2009 silverado with the 6L80 trans I do have the HD cooling package installed from the factory my question is will this be enough for the Circle D 3K converter I'll be installing or should I replace the factory cooler with the tru-cool 40k??? Trans temps now in this Houston 102* weather stay around 175-185...Any suggestions.

 

with my tru-cool 40k and 3000 stall my temps never got over 160 while nelson was doing my street tune and that was an hour or more of lead footing it.

 

Dam that's cool!!! What are the temps like in Austin??
