1993 Honda Accord 4 cyl Two Wheel Drive Automatic 215000 miles
got D4 light blinking chk codes got #8, chk connection and connetor was burn, replace it then chk TCM and was burn also. Send the TCM for repair installed, run good for about 200 miles the with no codes and no D4 blinking car start to shift erratic (at hi RPMS). Chk for ohms got 14.6 on the upper solenoid and 15.5 on the lower solenoid, chk continuity from TCM to solenoid connector and it is good, then chk for voltage at the connectors and in the upper set of solenoids it got 10 volts on both cables in Park and when put car in D4 or D3 volts goes to 13. Then in the lower set of solenoids got 2.3 volts on Park and 12 volts when put in D4 or D3. Solenoid are clean and cliking. Then in the lower solenoids if I jump(12 volts Form bat) one of the cables and let the other one connected to TCM it shift properlly to second but 4 and 4 will not go.
