Kind of what I was thinking but cannot find any reference to an S model.
The "S" on the tag means an electronic speed sensor has been installed.
Pulling the motor out of the truck. Got just about everything disconnected but the trans and exhaust. Will actually pull the motor tomorrow. Calling "a guy" to see if I can get my 09 harness that is set up for a 6l80 to work with a 3rd gen 4l80 or buy one. Probably end up buying one. Oh well. Do what you gotta do. Ordered my PATC 2800 stall converter. Making a lot of progress so far. No unforeseen problems except a small leak on the front of the 6l80. Looks like it just started. I was told when I got the truck the engine and trans had 78K on them (body 300K) but no documentation. Both the engine and trans have been out of the truck before.
I am trying to decide the best direction to go with my harness and controllers. I knew months ago that intermingling older and newer parts would present compatibility problems. So I have a 4l80 Gen 3 transmission, a LY6 Gen 4 engine with a Gen 4 donor vehicle that has a 6l80. What is the best way to make the 24x and 58x work together? I spoke to a local LS1 guy who can make a Gen 3 harness for me and use the Lingenfelter conversion box. Is this the best solution for my application? Total cost for harness, Lingenfelter and basic tune is about $650. Are there better options? I'm not using VVT but want to keep DBW. Any suggestions appreciated.
Everything is disconnected and ready to pull out of the truck. Beau was getting some early morning sun.
