Question type: Maintenance & Repair

I have a 93 Honda Accord and having issues with power.  The "P" light and the "D4" light will stay on.  This has been happening and the d4 light would flash.  It would cause very low power, so I learned that when I start the car, make sure the d4 light isn't flashing.  If it is, I would turn the car off and then turn the key over to see if it was still flashing before I started it.  The problem now is the light isn't flashing, it's staying on.  I had to drive home at 30 mph because the transmission wouldn't kick in.  After driving 10 miles, it all of a sudden kicked in.  This morning, went to leave and the car wouldn't even pull the hill in D4.  Had to put it in D2 to get it to go.  What do you think is the problem?

the clutches are probably smoked. It probably needs a tranny which is usually worth a couple thousand...

you really need to check your codes 1st be4 listing to that dude about your trans is toast. The pass side kick panal there is a 2 pole BLUE conector. Jump it off with a paper clip and turn you key but don't start the car. You "d4" light will blink your codes. long blink = x10's short blink = x1's (so if you get a long blink and 2 short blinks your code is 12) here is a code list for when you check your codes...Use the TCU codes for the trans long blink = 10 short blink = 1 1 O2A - Oxygen sensor #1 2 O2B - Oxygen sensor #2 3 MAP - manifold absolute pressure sensor 4 CKP - crank position sensor 5 MAP - manifold absolute pressure sensor 6 ECT - water temperature sensor 7 TPS - throttle position sensor 8 TDC - top dead centre sensor 9 CYP - cylinder sensor 10 IAT - intake air temperature sensor 12 EGR - exhaust gas recirculation lift valve 13 BARO - atmospheric pressure sensor 14 IAC (EACV) - idle air control valve 15 Ignition output signal 16 Fuel injectors 17 VSS - speed sensor 19 Automatic transmission lockup control valve 20 Electrical load detector 21 VTEC spool solenoid valve 22 VTEC pressure valve 23 Knock sensor 30 Automatic transmission A signal 31 Automatic transmission B signal 36 traction control found on JDM ecu's 41 Primary oxygen sensor heater 43 Fuel supply system 45 Fuel system too rich or lean 48 LAF - lean air fuel sensor 54 CKF - crank fluctuation sensor 58 TDC sensor #2 61 Primary oxygen sensor 63 Secondary oxygen sensor 65 Secondary oxygen sensor heater 71 random misfire cylinder 1 72 random misfire cylinder 2 73 random misfire cylinder 3 74 random misfire cylinder 4 80 Exhaust Gas Recirculation insufficient flow detected 86 ECT Sensor (Engine Coolant Temperature) circuit range / performance problem 90 Evaporative Emission Control System leak detected in the fuel tank area 91 Fuel Tank Pressure Sensor low input 92 Evaporative Emission Control System insufficient purge flow TCU Codes: 1-Lock-up solenoid 'A' circuit open or shorted. 2-Lock-up solenoid 'B' circuit open or shorted. 3-Throttle Position Sensor circuit open or shorted. 4-Vehicle Speed Sensor open or shorted - No signal from speedometer. 5-Shift Lever Position Switch circuit shorted. 6-Shift Lever Position Switch circuit open. 7-Shift Solenoid 'A' circuit open or shorted. 8-Shift Solenoid 'B' circuit open or shorted. 9-Counter shaft or transmission speed pulse generator open or shorted. 10-Coolant Temperature Sensor open or shorted. 11-Engine RPM (Ignition coil signal) open or shorted. 12-(No code 12 used) 13-Main shaft speed pulse generator open or shorted. 14-Linear (line pressure control) solenoid open or shorted. 15-Kick down switch circuit shorted
