Hard Shift into Reverse

[HBKidJr]

Hey guys. I'm having an issue with my 6 speed Silverado I was hoping you all may be familiar with.

 

Whenever I put the truck into reverse, there's almost a lag. It shifts, atleast, it sounds and feels like it does, but when I let my foot off the brake, it's like it just suddenly finds reverse and starts to backup. Just a sudden jump into reverse. I can't really find anything on this, so I was hoping I might be able to get some ideas from people smarter than myself about these things. Thanks!

research 6l80/90 Tecm  diagnosis, lots of you tube vids.  or call the techs at Circle D transmission, all they do is rebuid , you can probably mail him the Tecm for testing, or if your a parts changer type not into doing diagnosis, you can order a new one from Dorman thru a parts house.
