Anyone on here rebuild trannys , when i shift to drive there is a delay a( few sec. ) before it engages . Thanks for any info .

overfill the tranny 1 quart, and if that does not work then the input frictions are burned.

4l60e are knowing for electric mess ups best thing I going it to buy can of the red seafoam tranny stuff and it will clean up the 3-4 electric shift
I like to use it every other fluid change hope this helps only use half a can unless it really bad
