Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Its possible your programmer has ruined your computer and parts on the engine and transmission. At first this looked like a turbo pressure issue where as the turbo was making to much boost but as I read more the symptoms other than the hose blowing off do fit that of a torque converter clutch stuck applied from a mechanical, hydraulic, or electrical command. If you remove the programmer and reset the truck back to stock what concerns do you get?
This is my 1st answer, but does not have to be my only answer. You the website and myself expect you to have a great experience with my help. Please let me know if you are pleased by selecting a star rating above or by replying and saying your pleased. Not rating or rating 1-2 stars does not benefit you nor me in any way. Follow up and reply as often and when needed, there is no extra charge to do so.
Since the programmer is now not in use on the vehicle. After 5 drives can you tell me what codes are stored?
Do you have the tools for diagnosing and repairing the transmission if need be?
Will your tool show trans fluid temp, that reading wrong can cause the converter to always be engaged. The converter should engage in the 2 highest gears and above 45mph to reduce trans temp and to increase fuel mileage.
High trans temps would be from the converter clutch slipping or the temp gauge reading incorrect.
You need to diagnose and fix each code then address symptoms not storing codes. If I knew the codes I could provide the diagnostic steps.
2610 normally means the ECM is faulty https://dl.dropboxusercontent.com/u/90220402/2610.pdf
0700 means a better scan tool is needed to get the transmission codes.
