TRNW-2: 6L80, interchangability

[Dan Hogan]

John,

Some ID Info for you to reference.  Follow Jim's advice.

The output speed sensor will need to match the type of gear you have installed.  The late design is shown on the right here.

I have a built 2012 core shelf unit. I was under the impression that these were all interchangeable beside the 1 or 2 hole bell and vb/ techm. I plan on installing it in an 18 vehicle using original vb/techm from vehicle. When I went to prepare it I noticed oss reluctor wheels are different on rear planet. Both have 36 gaps. Has anyone had an issue doing this or does it work fine? thx for your time.
