I have a HD2500 6.0 gas that I might add a 6 psi Maggie to for better towing. If you have done this please post up your results. Good or Bad points appreciated.

 

my 2500 had a turbo and i towed quite a bit with it...no issues what so ever...my '05 avy had a radix 112 and towed with it with no issues and my current 1500 with TVS 1900 tows alot and it is great for towing but i dont like the 6 speed...wish it were a 80e

 

What kinda IATs are you seeing while towing?

I towed the Tahoe home Friday and with the turbo i never saw over 110* and it was 90* ambient.

 

I have 05 vortec high output with radix. Tows great, power is great but it loves fuel. About 8 mpg with 27 ft boat about 7500- 8000 lbs . On 2500 because of suspension its gotta be a great fit. I'd say tranny cooler is a must Alex

 

Deffinatly need a trans cooler.. 40K trucool is what just about everybody will suggest.


I love my turbo, but never driven a SC truck. so no help here....

 

I have the factory aux tranny cooler in front of the radiator. Looks small.

 

Get you a Trucool 40K and you will be set!

Quite a bit bigger than your stock one
(top cooler)(bottom is a TVS1900 heat exchanger)

 

That makes the stock cooler look pathetic!!!

 

You aint kidding..
Its nice!
I towed the tahoe about 18 miles with the converter unlocked the whole time and playin in boost the whole way. Trans got up to 170* is the highest i saw.


The trucool 40K is 8.5x22x1.25"

 

With my boat and in south fl with cooler max I seen was 190 with old 3.73, normal trans temp 150
