1998 cherokee xj - 4.0 with aw4 132xxx miles
-problem: when i use my jeep and put it in drive it will start off in third gear. It wont downshift while driving and occasionaly wont lock up on the highway. If i shift into 1-2 it will go into first. if i shift through the gears they all work but it still wont down shift. It was throwing code for the shift solenoids so i ordered new ones(all 3). i took the old out(which still tested good). So far this is what i changed: all 3 shift solenoids, trans filter and fluid(drained, refilled, and drove, then repeated twice), changed the tps, adjusted the cable, and cleaned the nss, and switched the tcu with a junkyard tcu. Still no change. Wont downshift or drop to first from a stop. Im at wits end with this thing. Any help or suggestions would be much appreciated. im still throwing code for shift solenoid b. thank you
