Car takes a while to shift between second and third gears. Car also revs excessively when changing gears. For instance, when I am on the highway I will accelerate to sixty mph and the car revs loud at 4,000 rpm. If I relieve pressure on the gas pedal and then immediately apply it again, it then shifts gears and the rpm's drop to normal. When I am slowing down from highway speeds it will jerk as its de-accelerating from third to second gear.

I realize this is likely transmission related. But I am hoping there could be an easier solution? Throttle body dirty? Spark plugs? Thanks

Hello,

It sounds like you have a shaft speed sensor that has gone out, please run the codes to confirm. Here are a couple of guides to get you started in the right direction.

Thanks Ken. Drove the car yesterday and it was noticeably worse. Jolting when shifting through gears. Got a check engine light and the codes were: 62-1, 83-1, P0685.
Hoping its just a battery cable or pcm relay. Ended up taking it to a mechanic with proper diagnostic tools (and for a separate issue). Will update when solved.

At the moment this is thought to be a bad battery. Trying the new battery for now -- so far so good. Possibility that its a bad starter. Mechanic also suggested I have the software updated at a Honda dealer (this is a 2005 - is this really necessary? Also -- how can I find out if I have the most up-to-date software already?) Will update this as things progress.

I had the battery replaced and the problem is now worse. When driving, I get a noticeable shudder between 1st and second gears (or a jolt when it switches). Today while this happened it was accompanied by a click sound from the passenger side (fuse box?) Until at one point the wheel froze up and it went into limp mode. I'm worried now that this is a problem with my PCM. Could a faulty fuse or relay in the passenger side fuse box cause my car to shudder between gears? Or cause it to go into limp mode? Thanks

It sounds like a speed sensor, please scan the computer for codes.

The code I have is P0685.
Question: If it is a bad relay (PGM-F1), do I need to disconnect the battery when I check the relay? Or if I replace it? Also -- if it is a ground wire (G101 perhaps) - do I need to disconnect the battery to remove the ground to clean it? Or can I do all of this while the battery is attached? I am trying to troubleshoot small things before I bring it back to the shop. Thanks

Yes it could be a bad PGM relay which is a common problem. Check the relay with the battery connected and clean the ground and positive to the battery

Please let us know what you find.
