My honda 2003 jerks when i change gear from to Reverse or Drive. Also, when on Neutral or Park, the revs/s is about 2. i dont know if that's normal. thanks

Your accord is slipping out of gear..check it one more time..

Who care about the Service soon light,since you stated you are a 1993 you are OBD 1,this is not a bad thing but if you pulled a code it would probable read 02 lean bank 1, The real problem is the whole transmission,Wont rev higher in other word its slipping,need to rev higher just to start moving ,well its slipping the solution is a rebuilt transmission,or a better car.

your transmission needs replaced.

If it's an automatic trans and you mean it revs real high(like in nuetral)then jerks into gear then the ****** is going bad.check to make sure the fluid level is right(do not overfill) and check to see wether you are leaking any ****** fluid.Also if you pull the ****** dipstick and it gives off a burnt smell then you know its going up.

Sounds like lean operation. Is the engine light on?

Had the same problem. to shift gear manually with your hands. Look under the brake fluid (about a foot down) and there is a flat piece of metal. On the end of it on the bottom is a little rod with a round end. That is where the shift cable connects. pushing it toward the driver side of the car will put it in park. And if you count the number of clicks from park you can change gears. For example: 1 click from park is Reverse, 2 clicks is Neutral, 3 clicks is Drive. That is if it is all the way towards the driver side. Don't force it. when it stops clicking dont push it anymore. Hope this helps.

A delay of more than a second in shifting from the neutral to drive or reverse gear, could mean that there is a problem with the transmission. If on changing from a neutral or park position to the drive or reverse gear, the car does not immediately catch the gear and move forward or backward, then it could mean a problem in the transmission. If you change gears, and you hear a sudden clunk or sudden jolt or shudder, then the shifting is not smooth and there could be a problem with the gearbox. If the engine rpm keeps increasing but there is no increase in the speed, then it could be a sign of the transmission slipping.Most automatic transmission systems, nowadays, have a check engine light or an OD light, which flashes if there is a problem with the engine.

Brake switch possibly, Or an unrelated problem, the neutral safety switch. both cam be problematic with 1999-2004 hondas.

on most newer vehicles the rev limiter is lower in park or neutral than in gear. i dont know why gm is doing this i just know that its normal. i dont know what year they started this but im guessing that is what your seeing. does it run fine in gear?

First on my suspect list is a transmission problem. Check the level of your transmission fluid, and if low, add to the MAX line. If the problem persists, report to your nearest transmission shop.
Also, experiment with gears other than Drive - see if car has same problem in 1st gear, and 2nd
gear (if your car has it). Also try starting car in Neutral - a properly functioning transmission will let you start your car in only 2 gears: PARK and NEUTRAL, thanks to the neutral safety switch.
