SES Light and OD Blinking [updated: codes read + solenoid pack pulled]
My SES light has been on and off for awhile now, used to come on only after more then 20mins of driving and usually it would go away after I turn the truck off, but now it is on all the time, (engine seems to run fine) and more recently the trans OD light has been flashing also, usually after more then 15 mins of driving, and after it comes on the trans will shift quite hard, (I have read this is limp mode, which is increases line pressure). Sometimes it won't shift into overdrive, it stays at 2500rpm on the highway doesn't matter what you do with the pedal then it will all of a sudden shift into OD after several minuites of not shifting...
I had the OD light blinking awhile ago and i cleaned the VSS in the rear diff and that made it go away, this was only a few weeks ago so i'm sure that isn't causing the OD light blinking this time.
I have checked the bypass tube after 20minuites of driving with the OD blinking, and the tube is cold, so I guess it's not the trans cooler bypass valve setting an overheat code...
I'm guessing my torque convertor is on its way out, or gone, I guess I need to take it in a get the codes pulled, I was just wondering is anyone has had similar circumstances?
What are the simptoms of a bad torque convertor?
