4l60e won’t shift into 4th OD with new aluminum pan 1997 k1500 5.7 4x4. Trans was working fine with original steel pan. It is original to truck with 209k currently. I have done the oversized TCC valve 20k ago due to p1870. I just installed a new aluminum 2 7/8 deep pan. Now trans won’t shift into OD and eventually lights SES with p1870. Checked fluid hot in park idleing and it’s at the correct mark. 4l60e is the older one case design with bell housing molded into case. See below pics of Dents Dimple in steel pan. Valve body adjustment? solenoid adjustment? Or need new valve body?
