You 100% need a dealer or a very specialized repair shop.

they are correct change the fuel filters

you can try unplugging the battery for few days. not guaranteed that it will do, but you can try it. if not, than you can get just a simple code reader from sears for about 75bucks and do it like that and after that you have a code reader for the future. if you dont want to do that, then you need to go to nissan dealer, pay 45 bucks (half hour of labor??) depending on a dealer and have the light/ecm memory erased and not have a code reader for future issues. I would buy code reader and erase my self and keep code reader.

Transaxle could be the problem.

this Happened to me. change your transmission fluid and filter. you may want to check and see if you have coolant seeping into the transmission fluid. this happened to me

how mny mils on vh if ard 100000 change trns fluid and filter

i will assume that you are referring to the clutch master cylinder , you bleed the system at the clutch slave cylinder located on the transmission bellhousing

Resetting the computer is usually done by disconnecting the negative terminal on the battery for a few minutes then reattach.

If you havent already try to change the transmission filter.Sometimes when the filter gets dirty fluid pressure is comprimised and certain pumps and solenoids which control shifting inside the transmission function off of the fluid pressure,

What you need is a "revolution sensor" I had the same exact problem. Replaced the sensor and everything is fine
