I need the wiring diagram for the speed sensor for a 1993 honda accord. my transmission suddenly lost speedometer operation and it will not shift from D1 when shifter is in the D4 or D3 position. I have replaced thespeed sensor and pulled the speedometer gear and inspected it. No visible damage and it is turning fine.

SOURCE: Gear Position light D4 is always flashing irrespective of gear.

This issue is caused by a transmission fault or malfunction, most likely a shift solenoid in the trans has failed or the trans control module has a problem, the trans can be tested for codes that will show what circuit or component of the trans controls is causing the light to stay blinking, have it tested.

First thing to do,try to pump your clutch before you shift into 1st gear then if you feel makes better, most probably you have problem with your hydraulic clutch system, check the clutch line if there is an evidence of fluid leaking or it could be internal leak.

Second thing to do, check your transmission oil, may be it' s too old or you use a thick oil thats why when cold its hard to shift then when the engine rich the normal temperature(warm) the oil become thin and the shifting will smooth. Remember the very old oil become thicken and the purity is gone and can cause of hard shifting. in this regards i suggest you to change the transmission oil and check the used oil if there is small peace of metals, then you are in big trouble,

Theres a transmission cooling sensor and somtimes the wire comes loose from other repairs being done around it. or its just out. its on the left side sitting on the tranny. THATS WHY your d4 light is blinking

Has anyone change the transmission fluid and used anything other than Honda ATF-Z1. If so, have the fluid/filter changed in this car and use only Honda Fluid. This is the only fluid that you can use in a Honda. Even if you have used the correct fluid an fluid/filter change may help. If that is not the case then I suggest you seek out a trusted professional.
