Limp mode or bad trans???

[RBell]

Hey guys!! Question for you'll, I started re-installing my cat and removing my juice Att. now all the sudden I have a big problem. Truck was running fine but just as soon as I took it for a spin today it felt like there was no power and it wouldn't shift into OD on the highway. Hell it wouldn't shift right using the shifter. It seems strange that it would just happen all the sudden like that. I thought maybe it went into limp mode?? I did pull one code, P0069, I believe thats something to do with the Map sensor. Pulled the battery cables and the code remains. Any thoughts on this problem.





Thanks in advance for any help. . ROB

Update

Ok guys I'm missing a ground from the transmission relay control in the engine control module. If I ground #85 on the relay for the trans in the fuse box everything works fine. Does anyone think a download from Smarty might resolve this issue? I would hate to take it to the dealer for something like this and hear all there crap. Any thoughts on this???Thanks ROB
