Okay so my boyfriend was driving my car doing about 50 maybe 55 cant tell you cause my spedometer wont work... but all of the sudden my car just stop going.. it started reving... not going. i ran the computer on it and it came up range sensor and incorrect gear ratio on gear 2 3 4? could my range sensor do that... also someone told me the speed sensor would cause my spedometer not to work... could that be right? please help me.. i really wanna fix my car myself...
The abs unit tells the ecu and the gearbox the speed and when to change gear if this is not working it could be one of these two the abs unit or the wheel sensor, the wheel sensor there are 4 of them in uk left front wheel is the speedo signal sensor, if abs system is dead i.e saying there is no faults or even connecting to a reader there is a fault. to determine the gear the gearbox needs the signal range sensor incorrect means there is a signal coming to the gear box but its erratic.

Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.

hi,
take the tranny pan off and look for small pieces of plastic in the fluid. sounds like a sensor got chewed up inside the tranny and small pieces of plastic have been sucked up and contaminated the internals of the tranny. look at where the wires go into the tranny and try and look inside where the sensor pickups is poking through inside to see if it looks normal in there. its going to have to go to the transmission shop. hopefully it wont be too expensive. as sensors are cheaper to fix then bands and internals. get two estimates.

Replace the transmission (gear ratio codes are 'absolute')... your transmission is unserviceable.

Probably a shift solinoid in the gear box. My commodore has 2 (1st & 2nd) & (3rd & 4th) my 3 / 4 solinoid went so went 1st 2nd 3rd but not to 4th until I replaced it.

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please
