Im not sure if i am posting this in the right section or not being new and all but i do hope that someone who is more tech savy than i am can answer this.

I have a 2001 accent, just recently i was driving on the interstate when all of a sudden the rpm went bezerk. it over reved then returned to normal two or three times then i dropped speed. From that point to home i was only able to have 1 gear forward so i had a max speed of about 25.

I got home and connected the snap on mt2500 to the system to read codes. Here are the 5 codes reported by the transmission.

P1709 Kick Down Servo Switch failure
P0734 A/T 4th gear ratio
P0733 A/T 3rd gear ratio
P0717 Input Turbine Speed Sensor failure
P0745 Pressure control Sol A Failure

I will admit i know very little about how a transmission works. So i dont know what codes are related either directly or indirectly. I would assume from this list that the Kick down, the turbine speed sensor and the Sol A are probably the most likely culprits in what is causing the transmission not to work in anything but 1st. Yes that is right i only have 1 gear and that is 1st going forward. No reverse or anything else.

Now going to autozone i see there is solonoids but i dont see anything called a kick down switch or a input turbine sensor. Anyhelp deciphering these codes and the location of their respective components would be of great help.

Thanks and have a great day
