Re: 2000 Blazer Stuck in Third Gear

P0756 - Shift Solenoid B Performance or Stuck Off

Schematic


CIRCUIT DESCRIPTION
The 2-3 Shift Solenoid (SS) valve controls the fluid flow acting on the 2-3 shift valves. The solenoid is a normally-open exhaust valve. With the 1-2 SS valve, the 2-3 SS valve allows four different shifting combinations.

When the VCM detects a 1-2-2-1 or a 4-3-3-4 shift pattern, depending on the state of the mechanical failure, then DTC P0756 sets. DTC P0756 is a type A DTC.
