I have a 2003 GMC envoy 4.2 engine A/T and when my car gets warm enough my first gear to second it kinda feels like i've been hit from behind really hard shift. Ethen after I drive it for a while the engine light turns on. An p1870 code shows up. We've replaced the pwm solenoid, pressure control solenoid, 3-2 solenoid and the manifold switch. Still same issue persists. Please get back at me as soon as you can. I will donate for you guys. Thanks. VIN NUMBER IS: 1GKES16S136207615
