4l65e problem
4l65e problem just rebuilt my transmission 250 miles later no 3 or 4th 1-2 shifts great reverse good. no shift from 2-3or 3-4 I set the 3-4 clutch pack at .030. Also the speedometer started acting funny and I got a check brake system light on at the same time.
I would probably start with trying to figure out your speedo and brake system issues first. Did you have this issue before the overhaul? Have you had your vehicle checked for codes? Have you dropped the pan to inspect the fluid?
