Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Range Switch
Range switch is located on console, near shift lever. On 1993 Elantra and 1993-94 Sonata, range switch contains a PWR (power) mode and NORM (normal) mode. When range switch is depressed to PWR (power) mode, an input signal is delivered to TCM, and TCM changes shift points to provide maximum performance. When range switch is released to the NORM (normal) mode, an input signal is delivered to TCM, and TCM changes shift points to provide maximum fuel economy. When engine coolant temperature is less than 68°F (20°C), transaxle will remain in NORM (normal) mode even if range switch is in PWR (power) mode. When range switch is in NORM (normal) mode and vehicle speed exceeds 60 MPH, transaxle will not downshift when accelerator pedal is depressed. Range switch must be in PWR (power) mode for transaxle to downshift.
On all other models, range switch contains a ECON (economy) mode and NORM (normal) mode. When range switch is depressed to the NORM (normal) mode, an input signal is delivered to TCM, and TCM changes shift points to provide maximum performance. When range switch is released to the ECON (economy) mode, an input signal is delivered to TCM, and TCM changes shift points to provide maximum fuel economy. When engine coolant temperature is less than 68°F (20°C), transaxle will remain in ECON (economy) mode even if range switch is in NORM (normal) mode. When range switch is in ECON (economy) mode and vehicle speed exceeds 60 MPH, transaxle will not downshift when accelerator pedal is depressed. Range switch must be in NORM (normal) mode for transaxle to downshift.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
