Transmission
1 Answer
2006 and 2007 were the "jump years" when GM started using input speed sensors in the 4L60E transmissions. you can tell by looking at the pass thru connector on the pass side rear of trans as long as the colors are the same ie: grey with green. you will have to unplug the trans to see the pass thru connector. other than that you will also need to look at the converter stall sticker (once out) there will be a few different most common is a TMBX but there is also a JMBX and TLBX if converter is not the same the stall point (shift) will be off depending on higher or lower stall
