Tranny Failure...help

[Franklin Joseph]

Well...somethings up with my tranny. Trans. Failsafe Prog popped up.
Was driving back from roadtrip...everything was fine on the highway....then got off the highway (stop go traffic) and noticed tranny acted abit weird, when i come to a full stop, it kinda jerks...did it a few times....then we got back onto the highway driving normal without any issues and then heard a funny sound and the Trans Failsafe Prog. came on and i think this is the limp mode. Its dragging and when i drive off the stoplight, feels like its in 3rd gear.

Any ideas?

Damn dealer is closed tomorrow, so i'm gonna take it in on Tuesday...but wanna check with yall first....is it still safe to drive around in this 'limp' mode?

I have the Peake tool...but not sure where can i plug it in the car to pull codes?

thanks
Franklin
