99 accord manual transmission trouble

It sounds like you are having an issue with your transmission not downshifting to first gear when you come to a stop. This can be caused by a variety of factors, including a problem with the transmission control module, a malfunctioning shift solenoid, or a problem with the transmission itself.
Here are a few things you can try to troubleshoot the issue:

1. Check the transmission fluid level and condition. If the fluid is low or dirty, it could be causing the transmission to malfunction.
2. Check the transmission control module for any stored trouble codes. These codes can provide valuable information about the root cause of the problem.
3. Inspect the shift solenoids for any visible damage or debris. If the solenoids are damaged or clogged, they may not be functioning properly.
4. If none of these suggestions resolve the issue, it may be necessary to have a professional mechanic diagnose and repair the problem. They will have the necessary tools and expertise to properly diagnose and fix the issue with your transmission.

1. check transmission fluid level or if you can change the fluid & filter.
2. check throttle position sensor (tps).
3. if fluid level & tps are ok & still not upshifting automatically, temporarily (so you can take it to a transmission specialist) , try to manually shift. starting from dead stop, shift to D1. at about 25mph shift to D2. (be gentle on the accelerator & don't over rev on each gear. release accelerator pedal & don't step on the brakes while shifting from D1 & D2).

there is a problem in your gear shifter located insde your transmission. have a transmission expert check your transmission, since this is not a DIY job.

mine does the same thing... check the relay behind the glovebox.

You need a new transmission because the gears have clutches and they wear or burn out with time or with abusive use.

It is the prnd indicator switch on the shift shaft of the transmission,or a shift solenoid,or the valves are sticking in the valve body,try some lube guard,added to the transmission,it is great for stuck valves.

i had the same thing...It's the transmission. It's REALLY noticeable shifting from 1st to 2nd gear. I was able to get my transmission fixed for 900 bux. That wasn't even a replacement so i can imagine how much it would cost to get it replaced. The shifting will get worse. By the end of my "experience" it wouldn't shift from 1st to 2nd for about 5 minutes until i drove it around for a bit. THen it would "warm up" to the idea of shifting to 2nd gear.

your linkage from the shifter to the transmission is out of ajustment, just tightin it up or loosin it witch ever it needs

Depends on the throttle position, there is a adjustment for that transmission. I would suggest someone who has Honda experience, like a dealer.

the trans will actually bolt up to the engine..but it will not work properly without the pressure switch plugged in to the harness... if u notice, there is a hole with no threads in the prelude trans..u couldnt even thread a 3rd gear pressure switch in the trans case..trust me ive seen it b4 at the dealer where i work.. i even went as far as installing the trans and when going back together, saw the difference when trying to plug the harness in...its not the same..i laugh about it now, but was very mad at myself at the time for assumeing the parts guy brought me the right part..the guy with the prelude was about to install my accord  trans in his prelude ...luckily i was able to stop him b4 he installed my trans in his prelude...i laugh about it now
