Adding Factory Style Auxiliary Trans Cooler Lines - Tru Cool 40K Install
@Doubeleive @Geotrash or anyone else that’s done this: Can you verify the flow direction through the trans cooler in the factor/original cooler in the radiator? Does it flow from transmission, to bottom connector in the radiator, then out of the top connector back to the transmission? Thus...- jeffm333

Adding Factory Style Auxiliary Trans Cooler Lines - Tru Cool 40K Install
Doubelieve - sorry for beating this to death but I want to be sure I get everything I need and I’m still not clear on one part - don’t you need an additional “male” end which has the factory quick-connect to connect to the output connection on the factory radiator/cooler? This is what the tech...- jeffm333

2013 Z71 Suburban additional transmission cooler
Working with the shop now to put them in series as everyone has outlined (and how I thought it would originally be done), and we have a snag: They have said (and showed me) that the inlet connector on the 2013 SUburban radiator isn't the same type fitting we got ind n the cooler kit or that...- jeffm333

2013 Z71 Suburban additional transmission cooler
Just had the transmission replaced in this truck and opted to have them install an additional transmission cooler. I believe it is a “supercool” branded cooler but looking at the receipt from the work it is not specified. Upon first driving it, after a 25-30 minute drive the trans temp was...- jeffm333

2013 Z71 Suburban for Overlanding - tire/suspension input request
@Doubeleive - that one in the car gurus ad is indeed sexy…. Would have like to have seen it 6 months ago when I was originally shopping. :) Although building them out is half the fun right? (Arguably the other half that isn’t fun is pure pain :) )- jeffm333

2013 Z71 Suburban for Overlanding - tire/suspension input request
This is perfect concise input - thank you very much. This being a z71 model… any idea how the mood 80069 I’m the rears compare to the z71 rear springs? Aftermarket bumpers, winch, and removing the factory step rails also potential future endeavors… I figure the step rails might come off...- jeffm333

2013 Z71 Suburban for Overlanding - tire/suspension input request
This winter I picked up a 2013 z71 Suburban to outfit as an Overlanding and long distance/duration road trip vehicle. I have the interior, solar, sleeping and storage platforms, cabinetry, fridge, house batteries, shore power/inverter setup complete and have been doing some light traveling...- jeffm333

OBDII Port completely dead - which control module presents this interface?
2013 Suburban Z71. OBDII port completely dead - won't power on generic scan tools. VXCNano is ordered, but I'm expecting it to also see nothing as the port appears completely dead, regardless of the key position in the ignition switch. I thought that the Body Control Module (BCM) would be the...- jeffm333

Diagnostic and Programming tool research - anyone use the Mongoose cable from drewtech / opusvis?
Looking at diagnostic/programming tools for 2013 Suburban Z71. I've neen researching the clone options for MDI, MDI2, Tech2 devices, and all the associated software. VXDIAG's VXC Nano seems to have had some people that have had success here, and some folks have some youtube videos out...- jeffm333

Complex Electrical Nightmare - BCM? ECM? Short?
This thread looks more like a "how to" for installing a secondary battery than a plea for input on a potentially fried BCM/ECM or other weird short.... for any moderators reading about my disaster, if this would also be useful in a "how to" section somewhere, feel free to copy there, or let me...- jeffm333

Complex Electrical Nightmare - BCM? ECM? Short?
INCREDIBLE train wreck indeed. With no instrument cluster and no ignition response with the key, driving it to a shop or dealer for help isn't even an easy option. I'll send a few pics of crude sketches/wiring-diagrams of the fundamental design of the system, give some background on my...- jeffm333
