I am attaching a photo of the bracket at the engines throttle body and hope someone can tell me if the unused square hole in this bracket (and the unused hole in the lower portion of the throttle arm) look like the standard arrangement for use with a 700R4 TV cable. Any other advice and info GREATLY appreciated. Is the rebuilder right about the 4L60 E in your opinion?
The 4L60E is the 700R4 with all the structural improvements made to the 700R4 over the years plus electronic control. The 4L60E needs a computer to operate, the 700R4 doesn't, that's the big difference. In 1990 the 700R4 was renamed 4L60 no E. It is the totally beefed up version as the earlier 700R4's had a lot of problems that GM was slow to address through the 1980's.
I'd say the rebuilder has problems with modernity, as the E requires that you not only know how to rebuild and automatic but also layers electronic controls on top of that. I say move on down the line, there's a lot of rebuilders on the web many specialize in performance mods, though they will redo a stock box as well.
