I have a 4l60e that occasionally misses second gear and goes into neutral on take off . If I let up on the gas it goes into gear and then shifts without a problem . I estimate it will do this on 1 out of 50 take offs from a complete stop . 99% of the time it shifts just fine . I replaced the VSS sensor but that was not the fault . Any ideas on this will be a big help . Thanks .

 

Do a Google search for "common 4l60e problems" and select the first result. It should be from gmtruckhq.com. I'd link directly, but I can't figure out how to copy the link on a Droid. There are a handful of possibilities when it comes to second going out.
