Tranny bucking
I did new tcc & lockup solenoids today, only to have it still hunting in 4th, my lockup switch still isn't working, and when I HAMMER on it in 4th or OD it bucks pretty hard. Really wondering what could be causing it to buck? Possibly torque converter issue? Still seeing 0753, 1765, and 1687 codes...
