Hi i drive a 2000 hyundai elantra and lately ive been having a transmission problem.I had this problem diagnosed with a check engine reader and the code that came up was P0707 which is the transmission range sensor(low input).Basically it has a hard time getting out of first gear but usually after driving for about 10-20 minutes it will unstick itself and all the other gears will change just fine.Im not sure if this problem is inside my transmission or outside.I havent changed my transmission fluid in forever it was basically a hand me down car lol i know thats bad so also could it be that its just low on fluid.???I'm hoping to find some information about this I've had no luck searching through the internet so if anyone knows any information about this problem or possibly how much it would cost to have repaired it would be greatly appreciated.. Thanks

 

You need to change the fluid on time. If you don't, then expect to need a new car since your car is worth less than a new trans. Try getting a trans flush and hope for the best.

 

You can start by unplugging the sensor and look for bend pins or rust in the connector. Once this is done you can try re-adjusting the range switch.

1. Place the selector lever in the "N" (Neutral) position.
2. Loosen the manual control lever lock nut to separate the cable and lever.
3. Place the manual control lever in the "N" (Neutral) position.
4. Turn the transaxle range switch body until the 12 mm (.47 in.) wide end of the manual control lever aligns with the switch body flange [12 mm (0.472 in.) wide portion].
5. Tighten the attaching bolts (2 pcs.) to the specified torque.
When setting up the switch body, be careful O-ring does not drop from the switch body. Tighten the attaching bolts carefully.
6. Make sure that the selector lever is in the "N" (Neutral) position.
7. Adjust the flange nut so that there is no slack in the control cable and make sure that the selector lever operates smoothly.
8. Run the vehicle and confirm that the transaxle is set in each range when the selector lever is shifted to each position.
