6L80 and 6L90 Transgo Tow and Pro - what it does and how it works!

Come watch Arley and me go through the in's and out's of TransGo's new "Tow and Pro" 6L80/6L90 reprogramming kit. This kit is designed to address common failure areas, like pressure regulators, pumps, boost valves, afl valves, pressure switches, stators, select valves, and tcc valves. It's a very comprehensive kit, and Arley and I attempt to figure out what the all modifications change.
This kit is also complimented by suggested "tunes" for those of us who like to tweak the transmission programming.
Arley tested our Cadillac CTSV on the dyno with the stock configuration, T-go kit only modification, and then T-go plus tune modifications. At the end of the video, I cover the results of those dyno runs.
Disclaimer - there's no doubt that some of my math is probably wrong, but the concepts should still hold true. If you know me, I like to know what a modification does before blindly installing it. That was the purpose of this video - to see what's being changed and by how much, and why!

Another great video! Thanks...used many of your videos for my 6l80 repair and upgrades!

I'm so glad I found this!

Where did you find a AWD 2nd GEN CTSV? I didn't know these existed? Also a lot of these PIDs don't exist for the T43 controller, I have found the torque signal PID to be missing from the truck TCMs. Not sure if this is just the HP tuners scanner not requesting and saying the right things to discover it or what.

Will this cure the delay into drive and reverse from Park?

[@hybridmusclegarage4590]

Great video. Where did the valve/spring tray come from? Thanks

[@juanlpz5189]

What's difference with this kit and a zip kit??

[@joshclark6101]

Great video. Can someone help me understand what the engine RPM drop is all about during the shift. What is causing it exactly?

[@patrickwarden2933]

can we throw this kit in a 6L80e with a new converter just to keep a good trans working?

[@MoparMattt]

Sonnax zip kit or transgo tow and pro? Your opinion on this, it’s a stock 2011 soccer mom suburban no towing just that big ole heavy thing hauling all our kids just wanna make it more reliable since it is torque converter shuddering. Also what torque converter would you recommend?

[@billgatesc1072]
