Haven't seen a post about this yet: 95 GMC 2500 6.5. Upshifts and downshifts fine, TCC locks ok but when I come to a stop it will downshift only to second. Then when I step on the accel pedal I can feel it downshift abruptly to first, jarring a bit. If I put it manually into first at a stop it goes into first. Am about to change the fluid/filter and was wondering if a bad 1-2 solenoid might be the culprit. Any thoughts?
