I got my Diablo chip a few days ago. I installed it after work Monday morning. Works great and I'm very happy with it. Just one small problem. When I cranked the truck up and drove off the next morning the transmission didn't want to shift out of first. Had to do it manually.So I've noticed whenever the engine is cold this happens, If it's warmed up it shifts normally. Is it just mine or is this something common to this chip? No big deal really just have to let it warm up a bit before taking off.

 

Sounds odd, I have no problems like your describing.
I would pull the chip, see if everything goes back to normal, re-install chip, and if the problem returns, IMO something is wrong with the chip.

 

I have not had that problem.

 

I also have not encountered those problems... Yeti is right on the money with taking the chip out and see if it returns to stock.

Ken would be the man to talk to... I have heard that, sometimes, it takes the chip awhile to "accustom" to the chip

Talk to Ken...
