I have an M1152 6.5 2009 4L80 transmission. I get it up to about 35~40 mph and that’s it. I never hear an upshift. It will over rev any more speed than that. I have checked the Brake switch ohms and it’s .3 ohms while driving and OL out of limits while braking I am unsure of what it should be. Do you have any advice? Maybe a valve body change and or fluid flush first with new filter? The TC light stays on.
Should've used the blue locktite bro lmao, love the content!
