Having problems with your 2003 Hyundai Elantra GLS ?

2003 Hyundai Elantra: Transmission "bucks" when moving to Reverse or Drive (when the engine is stone cold and the outside temperature is less than 20 degrees). The P-Code is 1723

\015 I own a 2003 Hyundai Elantra (almost 10+ years old, 99,000 miles). When very cold, the transmission "bucks" into REVERSE gear and also bucks (to a lesser degree) when moving to DRIVE; the power is also extremely low. The Engine Check Light (P1723) indicates either a Transmission Relay Switch or the pair of Speed Sensors (Pulse Generators). After about 10 minutes, the light goes off and the cars run PERFECTLY. This has reoccured about 5 times now; and only (so far) when the engine is stone cold and the outside weather is less than 20 degrees. \012I have to "gamble" and fix either Transmission Relay or Speed Sensor". I am leaning towards Transmission Relay. Another P-Code (P0715) seems to be more attuned to the Speed Sensors: that problem seem to cause the Transmission to drop to 4th or 3rd gear while the car is in motion.\012Based on my description, Which problem is more likely: Relay or Speed Sensor?\015 Posted / edited by AnonymousUser on : 25-05-2020
