2000 Accordlx eng. light on and drive blinks yellow code p0780?
I have a 2000 Honda accord. The drive light blinks yellow and the engine light is on. The manual says that it has to do with the transmition. It could just need fluid or have a major problem. I had a friend hook it up to his computer and the code is p0780. Any idea what that code means. I'm a single mom and I don't want to get screwed over by a mechanic. Please help.

Re: 2000 Accordlx eng. light on and drive blinks yellow...
Po780 is a trans hydrolic systen code
could be a shift solinoid gone bad
have an experienced mechanic replace the lock-up controlle solenoid control solenoid valve/shift controlle solenoid valve "A" assembley
and the A\T clutch pressure control solenoid valve "A"/"B" assembley
start with these two parts farily inexpensive if this doesnt solve the problem then the trans needs to be replaced really expensive
both of these parts are located on the out side of the trans

with a fault of "problem in transmission control " this is a very general fault , but a good transmission shop that deals with Honda's might have access to a borrowed control module to test it out , who knows you might have to only buy one of these not an entire transmission , accord to transmission's dot com a 2ooo Honda transmission lists for 1253.00 dollars rebuilt ones go for about 2/3 that price
Possible causes of OBD code P0780
- Low transmission fluid level - Dirty transmission fluid - Faulty shifting solenoid valve - Shifting solenoid valve harness or connectors - Shifting solenoid valve circuit is open or shorted The Error code is generally activated on detection of the following conditions: The P0780 codes is detected when no rotation change occurs between input (turbine revolution sensor) and output (revolution sensor) and shifting time is long or when shifting ends immediately or when engine revs up unusually during shifting.So check out these points and see if any are all help keep me posted
The code you have P0780 is an internal hydraulic problem in the transmission. I did some research on this trouble code and the repair manual Say's to replace the torque converter clutch solenoid valve/shift solenoid valve A, and the A/T clutch pressure control solenoid valves A and B.
In plain English these are the shift solenoids and torque converter solenoids. These solenoids control the fluid flow to the transmission and if they are not working properly then p0780 will set.
The bad news is the repair manual Say's to replace these solenoids and if the problem is still present then replace or overhaul the transmission because the problem is internal.
Most repair shops are not going to take the risk and just replace the solenoids, they will replace or overhaul the transmission.
The check engine light comes on if there is an issue.But Honda also has preset the Check engine light to come on to remind you of oil changes.If you want to shut the Check engine light off.There is a Yellow Reset Button inside the Fuse panel.
