I was hoping someone would have some insite to share. I don't know or think it is the actual transmission, but, I have it twice today not go into any gear. I got out to inspect the driveshaft, it was perfect. I jumped back in, turned off the truck, fired it back up, it was perfect again.
I entered the car wash, after if was done, shifted into gear again, nothing. From any gear. Turned it off again, fired it up and perfect.![Huh](https://www.performancetrucks.net/forums/images/smilies/LS1Tech/huh.gif)
My only thought so far is that it's a stupid electrical gremlin. I plan on disconnected the wiring harness from the transmission and cleaning it well with contact cleaner.
Does anyone have any other ideas or better yet, first hand experience with this? I have never had a single issue until today with it. Thanks.

I just wanted to say that within minutes of this post I had a PM from Andy at FLT to help me out. That is crazy service in my books. Two thumbs up so far for service. Once I find out what it was I'll advise.
