Q: transmission on 2004 Hyundai Accent

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
the check engine light went on; went to the auto parts store for a check engine diagnosis, was told that there was a speed sensor issue and multiple misfirings which could be the spark plugs or the cables. Replaced the spark plugs. now the car will not drive in reverse nor shift gears going forward. Does this mean I need a new transmission?

Please have a diagnosis performed by a professional. Not an auto parts store. They can't do it there. They can pull codes, but can't tell you what they mean for real and why they came up.

I can tell you that some Hyundais have OSS and ISS issues (that is output shaft and input shaft speed sensors). If the sensors are failed, it will pass faulty information to the processor about how fast the shafts are spinning. This will affect transmission operation.

Have a good diagnosis performed soon. Good luck.

just from what i read, it sounds as if your wheel speed sensor issue may in fact be a vss. or vehicle speed sensor, as it is called will give you a code such as this. it also controls the shifting of the transmission. have this verified at your trusted repair facility to avoid just throwing a part at the car!
hope this helps!
if the speed sensor is repaired could that avoid having to replace the transmission?
