I was just on their site and didn't see anything about it. I need a replacement 4L60 for my V8 Sonoma, and the TCIs are very expensive! Over $1000 more than having a reputable local place do the job.

I would have to try and dig through some old info but it is not the truck 6 speed. It's is a modified 4L80E. At least a month ago the only way to shift it was with a paddle wheel shifter, no other options were available.

Below is a quote directly from an inquiry to TCI

It's is actually a 4L80-E with a different planetary set (to change the ratios) with changes made to the valve body and to the TCU that it comes with. We do not have the final price yet, but it will be a complete package down to the dipstick.
The TCI version will come with an aftermarket planetary that has 2.97, 2.23, 1.57, 1.18, 1.1, .75 ratios as well as aftermarket mainshaft, input shaft, sprag assembly, stock depth pan and clutches. The complete package will come with transmission, converter, our TCU w/harness, paddle shifter for manual option, dipstick and cooler.
