Hi I have a 2001 blazer 4x4, recently it started not to shift I have to let go of the gas for it to shift to 2nd gear, it will not shift to 3rd or 4rt gear. Mechanics in my area say my truck is in LIMP MODE is this true?
They also say to check for codes related to the shift solenoids but I have no codes for that.
The weird thing about this is that I recently replaced both A and B solenoid when I broke the wire harness that connects the solenoids.
What could my truck have please help?
Thanks.
