How do you have the transmission codes checked for the speed censor

A speed censor would be a part which refuses to tell you how fast you are going. A speed sensor tells the computer how fast the final drive is turning, and thus is normally located on the rear section of the transmission and held in place by bolts or screws in place.

Well code 1698 means the engine computer could not communicate with the transmission control module. I doubt that would kill the engine, but there could be a wiring problem somewhere.
It could be a faulty relay too.

Check crankshaft sensor.

-Sounds like shifting solenoid is not working properly. (It's inside the transmission valve body)


Good luck

the S light is on more than likely because of you speedometer or your vss "vehicle speed censor" which is connected to your transmission im having the same problem on my 91 accord lx. check the codes and let me know what the codes are and i may be able help a little more if you dont know how to check the codes I can help with that as well

There are 2 speed sensors on the transmission. The input speed sensor is inside the side cover. remove the cover. disconnect electrical connector. remove retaining clip from cover. remove sensor.

The other sensor is the vehicle speed sensor. ( VSS ) on the left side of transmission, unplug the sensor. remove bolt, remove sensor. reassemble

the speed censor is on the side of the tranny it has a two wire pluggin going to it.speed censor are pretty easy to put in ,they just tread in to the side of the tranny.

I would get a used transmission with a warranty.

It sounds like an O2 censor, If it happens when your around that speed it could be the map censor or the 02 censor. You need to go to a garage and have them hook it up to find out which 02 censor is causing it.

It is possible for the Speedometer and Tac gauge not to work but will not affect the way the transmission works. If the problem is in the interment cluster the transmission can still receive the input from the speed sensor. Does the check engine light come on? If the transmission isn't receiving the signal the check engine light will come on and set code. If the check engine light isn't coming on or doesn't set code for speed sensor signal you problem is more likely to be in the interment cluster. The RPM would be the same.
