I have a trouble code which is throwing out 70 on the mil light and D4 light is throwing out a 2 signal. I know its a transmission problem. the 2 for the Lock-up control solenoid valve. I tested it with a known good one and still throwing the same signal.I checked my PCM connectors and its fine. My car stalls in the low gears but fine in the high gears. The car seems to be vibrating in gears but not in Park or Neutral.

Anyone have any answers?
