No automatic shift to 2nd gear
Hey guys was wondering if i could get a direction to go for troubleshooting this. I rebuilt my trans with some good advice from a reputable builder. It’s in a 03 Tahoe. I can’t the trans to shift to 2nd on its own. If I use my bi directional scan tool i can get it to shift to all gears and it drives good. Checked the line pressure and it was solid I can’t remember exact numbers. If I don’t shift it with the scanner it does show its commanding 2nd but just stays in first. Thanks in advance.
