Candidate cause (the documents say what to do)
4L60-E / 4L65-E clunk on 2-3 upshift or 3-2 downshift (normal condition)
Some vehicles may have a clunk noise on a 2-3 upshift or a 3-2 downshift.
On a 2-3 upshift the 2-4 band releases and the 3-4 clutch applies; the shift timing can cause a momentary torque reversal of the output shaft that results in a clunk.
