Question about Cars & Trucks
My transmission skip third gear!!!!!
Make sure the TSS sensor connector is good. Since you replaced the engine it is possible the wires/pins in the connector are loose or bad. I have seen where the wires break inside the insulation at the connector.You could have a bad TSS sensor (200-400 ohms good), if you have a multi meter we can check the circuits too. I would check the connector and then clear the code , test drive and see if it comes back. The PCM uses this sensor to control shift patterns so a fault is stored in the PCM. P0715 is for a loss of TSS signal during operation.
We can check the continuity but that will only show if there is high resistance. If there is a wire about to break(instead of 15 strands connected 3 or 4) we need to load the circuit or wire. If we put 12 volts through the wires(disconnected from the sensor and PCM of course) and we use a light bulb as a load if the wire is bad the bulb will be dim. I would start with an ohm check of the sensor and a close inspection of the connector.
We start with an ohm test on the sensor and then continuity test the circuit. Then we load the circuit. I have had the wires break as I disconnected the connector or tugged on the wires at the connector.

MIL Comes On With A/T DTC P0715
The MIL comes on, and A/T DTC P0715 (problem in the mainshaft speed sensor circuit) is set.
Retrieve and record the A/T freeze data with the PGM Tester. Make sure you record the freeze data values on the repair order. Refer to DIAGNOSIS to determine which of these repair actions is needed:
* Replace the PCM
* Flush the A/T
* Replace the A/T
* Troubleshoot the mainshaft speed sensor circuit
* Troubleshoot an engine problem
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

SOURCE: Speed Sensor
The Speed sensor on your Honda Accord 97.
Is located on the Transmission.
If you follow the Lower Radiator hose from the rad to the engine.
The hose end on the Thermostat housing.
OK.. Just on direction of the thermostat housing .
Under the housing you Will see on the transmission the Speed sensor, with a connector of 3 wires. Is the only sensor at this
Part of the Transmission..
Ok. I hope this work on your question.
Thank you for use fixya..

the output spped sensor is on the drivers side rear of the transmission case..its a 2 wire connector..the wires are dark bluewith a black tracer and light green with a white tracer

Your speed sensor, is located on top of the transaxle, near the starter. To access it, remove the battery, then remove the battery tray (4 10mm bolts). You will see wires coming from the lower oxygen sensor, and they snap into the bracket that holds the speed sensor in place. The actual speed sensor has a 2 wire clip on it, and is held in place by the bracket and a 10mm bolt.

SOURCE: transmission codes:
I WOULD TRY REPLACING THE INPUT SPEED SENSOR..A DEFECTIVE SPEED SENSOR CAN CAUSE ALL OF THESE FAULTS..IT IS LOCATED IN FRONT OF TRANS ABOVE SOLENOID PACK..IT IS THE ONE CLOSEST TO THE ENGINE..IT SCREWS INTO TO TRANSMISSION..A 1 INCH SOCKET FITS IT..ALSO CHECK WIRING TO BOTH SPEED SENSORS..A SENSOR IS ABOUT 35 BUCKS,AVAILABLE AT YOUR LOCAL DODGE DEALER..GET A NEW ONE AND YOU'LL SEE WHAT IT LOOKS LIKE..FAIRLY COMMON PROBLEM..HAVE REPLACED LOTS OF THEM

If you google 97honda input speed sensor you will find several pictures. (Go to google images and input the above).
IF your input speed sensor goes bad the trans controll unit see's an "incorrect gear ratio".
Check your fluid too. If it is clean, you probably do not have a Major problem I have been rebuilding transmissions since the 80's and only stopped in 06. I have had many that only needed a new sensor like the input or output speed sensor. Try removing the input first and clean off the magnet. It is a pulse width modulator that uses a magnet with lands of metal passing through the magnetic field and the computer counts the pulse made by a collapsing field to determine the speed of the input drum. It compares it to what gear it is in and what the output speed is and if there is a problem it will set the codes you see.
Sometimes find metal from wear in the unit will accumulate on the magnet interfering with the input. Other times the sensor just fails, either way, it is usually not bad unless something is tearing up in the unit to cause a lot of metal to adhere to the mag.
Hope this helps
