When do you get the p0780 code on Honda shift control system?
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.
What is the diagnostic code for Honda transmission lock up?
Diagnostic trouble code P0740 is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve. P0740 HONDA Possible Symptoms Engine Light ON (or Service Engine Soon Warning Light) Transmission shift shock Vehicle may not shift into the highest gear P0740 Honda Description
What happens when you have a bad Shift Solenoid?
Erratic shifting or shift slippage: The shift solenoids regulate the flow of hydraulic fluid for shifting. A problem with one or more of the solenoids can cause a lack of pressure, resulting in hard, soft or delayed shifts.
What does the p0740 code on a Honda mean?
P0740 HONDA Tech Notes On some Honda vehicles, the P0740 code may be set by an overheating torque converter problem which is caused by an insufficient flow to the torque converter release circuit. User Submitted Video What does this mean? Cost of diagnosing the P0740 HONDA code Labor: 1.0
What causes Honda shift control system to malfunction?
This malfunction is detected when the A/T does not shift as instructed by the TCM. This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such as control valve sticking,improper solenoid valve operation, etc.
How much does it cost to repair a Honda p0780?
An error occurred while retrieving sharing information. Please try again later. The cost of diagnosing the P0780 HONDA code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

What does it mean when your transmission says p0780?
They take note of the serial shift solenoid PIDs and determine if they are right, that is when the transmission shift smoothly from 1st to 2nd gear, or if there is a “flare up” in the RPM between shifts. If there is a flare up, then the problem may be indicative of a slipping transmission and may verify the Error Code P0780.
What is the diagnostic code for Shift Solenoid B?
The P0780 code means that there has been an abnormality with the transmission shifting. Note that this code only applies to automatic transmissions. This code is also often associated with other, similar codes, such as P0755 Shift Solenoid B Malfunction.
