I just installed a pcmsforless ECM in my 05 Escalade for towing. They did some minor tweaks to performance, that are noticeable. But I Really purchased to remove the torque management system while towing and change when and how long the fan comes on.

Paid $265 after the core charge. look them up!

I'm well aware if PCMforless. Alvin does some great work. I have a local guy I've been using for years to do my tuning though. Fast Motorsports out of Woodstock, IL. Small shop, the guys name is Brandon who runs it. Real stand up guy who will go out of his way to help you out. He can do a mail order tune, on the dyno, or on the street to get some real world Data while te boat is hooked up behind the truck.

Brought my boat home without issue yesterday evening. The Denali tows much nicer than my f250.

Nice setup

Thank you!

You might be surprised how hot the trans gets in stop and go on a hot day, the idiot stock gauges are pretty worthless,as is the stock cooler (running the fluid thru the radiator) but put a sender in the trans and I watch mine start to climb past 225* pretty quickly in Traffic.
Current set up is a thermostatically controlled fan assisted cooler.
Keeps that trans happy.

SnailLazer I lived in Woodridge for a few years.. I`m in Aurora now. Nice truck:evilb:

It was plenty happy on the way home yesterday, never broke 135*

+1 for the add on trans cooler. Mine has a plate style cooler built in radiator, and had a OE cooler in front of radiator. Replaced that one with a Derale cooler with a built in electric fan. Trans get warm, fan comes on, to help get some airflow across the cooler in traffic. Icdedppl hooked me up with that.

Havent hooked the boat to it yet, but around town and hwy, trans stays consisitant with coolant temp (150-160) on my autometer gauge. Running a Blackbear tuned pcm which helped a lot and tq management removed. More responsive and shifts better.

BTW Nice looking setup snailglazer

sure at 40* ambient

fixx
 

on your dually??? why,,that cooler is rater for 16k,,,i have the same cooler and i use to pull my dads cougar and never had any problems..all i did was add a b&m 9 qt pan and my trans stayed at 200*..

Im going to wait until I actually see some high trans temps before I go drop coin on a cooler. I was daily driving a trailblazer SS with a 4000 converter in it. That was a chore keeping trans temps down!
