Starting to Learn on 95 G30 5.7 for Towing

[donf]

This morning I decided to go in a different direction. I will track down the communication problems later. The engine runs perfectly and is not getting any changes for a few months at least, what I do want to change is the shift points. Since Switching from a 3.23 to 4.10 the shift points seem to be off a little. I think the first step in that is reading the factory memcal. So I looked for a BJYR bin here and did not find a copy. The van is a 1995 G30 van 5.7 4l60e, originally 3.23 gears (GU5). If you look up BJYR on the BCC lookup spread sheet you will see the mistake. Its listed as a manual transmission. That looks to be impossible since chevrolet never offered a manual transmission in the 1995 G30 van as an option. https://www.gmheritagecenter.com/doc...olet-G-Van.pdf - third page direct from GM = 4l60e or 4l80e. It also has been shifting the 4l60e for 108,000 miles. So now I want to read and save my stock BJYR bin file. I think I got it but not sure if its done right?

Edit: I removed the bin because it may be messed up. I got way different specs off of the same memcal with two separate readings.
