I see nothing I hear nothing
4L60- not computer controlled
4L60E- Computer controlled
Point taken, and correction on my part. The 4l60 not E, does use a detent cable.
However, OP did state hes looking at a
"4l60e and a 4l80e"
IIRC GM changed the designation of the 700 R4 to 4L60 to bring the nomenclature in line with all the new stuff. 700R4 and 4L60 is the same trans. Easy to add the "E" without thinking about it when talking about the 4L60.
