4cyl trying to find the service connector to see what code the flashing d4 gives meId like to do it myself if possible
Customer reply replied 2 years ago
I drove vehicle 50 miles to work this am started a mile from office and then on way home had issues not going into higher gear
Mechanic for Honda: Honda-Man, Honda Mechanic replied 2 years ago
OK, sorry to hear about your trouble. The codes most likely mean the transmission has failed. Your generation of Accord has the worst record for transmission failures. The scan tool reads the transmission codes from the OBD2 connector just like engine codes. There is not a separate connector to jump.P1738: Problem in transmission 2nd Clutch Pressure Switch Circuit. Code P0730: Problem in transmission Shift Control System. Code P1751: Mechanical Problem in Hydraulic Control System for Shift Solenoid Valve B and A/T Clutch Pressure Control Solenoid Valves A and B, or Problem in Hydraulic Control System. Code P1259 is a VTEC pressure switch code. Oil level or a bad pressure switch are common failures. Thank you for giving me the opportunity to assist you. Your satisfaction and accepting my service or providing a positive rating is what I work for! If you can't rate in this way please let me know so I can continue to help. A positive rating is the only way the site will compensate me for helping you. You can still ask follow-up questions after the rating.Thanks again! ~Honda-Man

Its possible its not a complete failure then . that a component just failed ?
Mechanic for Honda: Honda-Man, Honda Mechanic replied 2 years ago
P1751: Mechanical Problem in Hydraulic Control System for Shift Solenoid Valve B and A/T Clutch Pressure Control Solenoid Valves A and B, or Problem in Hydraulic Control System. This code is a bad one so is P0730: Problem in transmission Shift Control System. Before the codes will set the transmission needs to fail mechanically meaning it's slipping or the hydraulic pressure is low. Once this happens the excessive heat generated when it slips will take out the rest of the transmission. I have replaced well over a(###) ###-####02 Accord transmissions in the 4cyl model alone. Whenever these 2 codes are present the transmission is on it's way out. Sooner than later it will fail completely leaving you stranded. In our dealership we were on a rotation replacing transmissions so it was fair. Sorry again I hate giving this news. Thanks again, Honda-Man

How much would you say to replace it and is it worth it
Mechanic for Honda: Honda-Man, Honda Mechanic replied 2 years ago
A used transmission is risky so I would avoid that. Re-manufactured ones run $995-1200 labor is aprox $600. Total cost is aprox $1800 parts and labor. Rebuilding yours at a trans shop is a little less but not much. If your Accord was in excellent shape with a good transmission it worth approx $3700. If it's in average condition it's worth approx $3000. This info is based on Kelly Blue Book value.Thanks again.~Honda-Man

Your answers were clear and the diagrams were perfect. Dealer wanted $87 for an hour of labor and even I did it in 15 minutes.

HONDA PLATINUM was great. I really appreciate his help. I was ready to trade my new Honda until he told me to wait until I got 3,000 miles on it and my gas mileage would get much better.

SummerUSA

I took the Power Steering O-Ring service bulletin linked from JustAnswer to my Acura dealer, and not only did they no-charge the o-ring, they also replaced the power steering pump at no cost.

Gary RStevenson Ranch, CA
