Have 2000 honda accord sedan with 242000 miles I know im starting to getting of slippage in the tranny had got 4 codes p135 p0304 and then p1739 and p1399. The 1739 and 1399 didn't have a explantation for these codes. Hoping someone here could help me find out what the codes and how to resolve them. Only an idle the cel flashes put when you take off to drive it quits flashing and just stays on like in the past.

P135=didn't come up with anything...if you meant P1305 or P0305 both of those come up with a Cyl 5 misfire
P0304=Cyl 4 misfire detected
P1739(honda specific)=TCM A/T controller circuit
P1399(honda specific)=Random/multiple cylinder misfire detected

This is what my OBD 2 library comes up with, hope it helps. One of the smarter folks here can maybe help you out with the troubleshooting but will probably need more info about the problem. Good luck!

If you meant P0135, that is for the Primary O2 heater.

P1739 is actually for the 3rd clutch pressure switch.

Not sure where you want to start? Me, the mis-fire - flashing CEL are the most important.

EDIT: a few more details like engine size would help.

It is the 2.3 4cyl. When in park is when the Cel starts to flash shortly after being placed in park. Not sure of the four codes I have would cause the cel to flash p0304,p0135,p1399, and p1739. It also have a rough shift kind of delayed shift at 3rd gear it is Auto trans. As far as driving the cel doesn't flash just stays on and on the highway run smooth trans and engine wise

Change the tranny fluid with honda fluid 5k miles ago

Plugs are new
Wires about six months old(10k miles
Distributor cab and button maybe 1.5 yrs (15k miles
ran seafoam thru gas and a little in the engine.
