This is the modulator, which uses engine speed to control the shifting. You are experiencing what is known as hard shifting, a common complaint of modulator failure

I have a 1996 Honda Accord with 268k miles that sputters at the same timethe speedometer needle fluctuates wildly. But I do have a new Vehicle Speed Sensor. This typically only happens when the engin


I am no Honda expert, but a similar problem happened to my ex sister in-laws Ford Taurus. The speed odometer would jump around and it had trouble shifting (automatic transmission). After driving it I changed out the speed odometer sensor on the transmission and it's been fine ever since. I changed out the sensor because if the cars computer cannot tell how fast the car is traveling then fail safes in place go into effect and the computer will do it's best to keep the cars rpm's down based on the speed indicator and not let it shift or shift properly either. If it's getting false speeds then it will shut down the motor when the speed gets to high and allow it to run as the speeds fall (jumping speed odometer needle). It effects the transmission shift points also. It will either shift erratically or not shift out of say 2nd gear, so that the cars engine can't get damaged based on what signal the speed sensor is sending the computer.

My speedodemeter is off by 8 miles an hour could that be fix just by changeing out my transmission because the transmission doesn't shift right it takes a min.


Assuming you replace it with the same transmission it should be fine. If you've changed your tires to a larger or smaller size it can also effect your speedometer. If this is the case it can usually be corrected by replacing the speedometer cable with one for that particular combination. If your transmission isn't shifting right you should check the fluid level. Also check for any transmission leaks because those can effect the shifting as well.

Car shifts hard (up & down), especially shifting to reverse.


that delayed reaction may be the transmission slipping. with those many miles it could be the transmission going bad

Speedometer


Your speed sensor is on the transmission on the drivers side mid way down the transmission dont think they run that much and are easy to replace. Should be a hard plastic coated thick wire.

Transmission shifts hard


Your car has the 125c/3T40 model trans,3 speed automatic with lockup.When you say you unplugged the "speedometer",if you are referring to a square electrical connector on the trans,facing the radiator,that connector is not the speedometer,but the lockup circuit inside the transmission.It is likely the lockup solenoid inside the side pan has gone bad and is malfunctioning.It is a common problem on those transmissions.You will lose some gas mileage by unhooking the connector,and eventually,years down the road,will hurt the trans from the fluid running too hot.Lockup clutch application in a General Motors lockup torque convertor helps to cool the fluid.

VSS (vehicle speed sensor) Tells the PCM (computer) the speed of the vehicle so the PCM can make the proper information to the TCM (transmission control module) to shift.
YOU are goin gto need a scan tool NOt a code reader to monitor the VSS to see what it is putting out for speed when the car is moving But I believe you need a VSS but do not not Go out and buy one until you have had it tested , and can positively confrim it is bad first. Please rate this a fixya if you find this advice helpful, Thanks Randy
