You're limping the tranny, lower the tune and be more gentle on it. Once the trans limped, it starts getting limped easier.

Can it have to do with a bad cylnoid I had this problem right when I got the chip and it did it once transmission guy said he thought the cylnoid was malfunctioning. it does it when I start the truck up and it will go to third gear and stay there its not when im driving does that change anything?

You need to fill out your signature with the year and any mods-- that helps when you ask a question. Click User CP top left.

You need to post the code- otherwise we will have to "Guess" ! There are many Techs on this site and they will gladly help.

Uh yeah the tranny will limp from power and stick in third..... I did it when I had my PPE on level 5...... it's the clutches slipping that makes it limp. All you can do is stay out of it and save up for a rebuild...... sux.
