Where is the transmission range switch on 2001 honda civic

What is a neutral safety switch? The PRNDL switch is on passenger side of transmission. Pull passenger side front tire off and and it's visible. You have to remove a metal cover, two bolts. That switch tells the car what gear it is in.Here's a link to what it looks like 2005 HONDA CIVIC 1 7L L4 Neutral Safety Switch Range Sensor RockAuto

There are adjustments to be made on the outside linkage of your transmission. Take it to an honest transmission shop that won't tell you to replace the whole transmission.

in the side of the tranny big plug going in to it

A. DTC P1705: Short in Transmission Range Switch (TRS) Circuit. The TRS lights the A/T gear position indicator in the instrument panel shows which gear has been selected.

The PCM also uses this information in order to manage the fuel system for maximum efficiency. The most obvious symptom you will see is the A/T gear position indicator lights will not come on or come on in the wrong position.

Once this is repaired emissions should pass

what would cause the 2001 honda civic to over heat after brand new water pump theromastat timing belt and alternator blet replace yesterday and when it overheated i pulled over and checked all the fluids i had like oil or transmission fluid all over my under part of motor alittle on my breather and top part of hood , the oil also has a tendency to smell like gas but its not oil/gas mixture please help

please specify what your problem is.

your vehicle is not equipped with a cvt transmission, so does not require cvt fluid. adding cvt fluid would cause a catastrophic failure. please reply and explain what problem you are actually experiencing.

Honda Civic 01 has a defetive torque converter that prematurely fails. Same issue with the Odyssey 03 to 05. (The difference is Odyssey got a recall whereas the Civic did not). When it does, debris gets into the transmisson thereby clogging the filter and sometimes ruins the gears. There is no drop pans for this type of transmission and the filter is located inside the transmission housing itself which renders it to be serviceable by transmission shops ONLY. Most often, when the torque converter fails, the entire transmission will need to be overhauled or replaced. A cost that could run from $850 for a rebuilt to $2000 for an OEM. The best cost effective way to remedy this siuation is to replace the torque converter before the mileage reaches to 100K. A rebuilt one only cost $120 or $700 for an OEM with labor ranging around $350. Far cheaper than a transmission replacement. If your Civic 01 is still running and it is beyond 100K, run fast to a transmission shop and replace the torque converter immediately. If the transmission is already starting to slip, replace the torque conventer and flush the transmission and pray that the tranny was not significantly damaged by the debri. Remember, the recommended trans fluid change for Civic is 120K / 6 yrs or 30K / 6 months if driving in severe conditions.
