P0732 Hyundai Code - Second Gear Incorrect Ratio

Quick Answer

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows: Torque converter slip ratio = A x C/B A: Output shaft revolution signal from revolution sensor B: Engine speed signal from Engine Control Module (ECM) C: Gear ratio determined as gear position which TCM supposes If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than normal. Common causes include Low transmission fluid level, Dirty transmission fluid, Faulty Shift Solenoids. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Discuss the causes and fixes for P0732 Hyundai OBDII Code

  • is occurring is failure in a Tucson, oil is clean and on level, which selenoide I change?

  • Let me get more information. What year is your Tucson?

  • 2010

  • the car is struggling in second gear, and also has the code C1208 and C1211 in the ABS, which are the speed sensors of the rear wheels, this may have some relation?

  • If the problem were the ABS sensors, then the sensors will affect all the gears and not just the second. A faulty Shift Solenoid usually improves with new transmission fluid, and if the problem is the solenoid, it requires removing the transmission pan and transmission valve body to access the solenoid. Due to the age of your Tucson, the problem is more than likely mechanical. I recommend having a transmission shop diagnose the problem.

  • Thanks for the help

  • I have accent hundai 2016 it has p0732 (gear 2 incorrect ratio) code, when I pass over 40km/h it stucks in gear 4 and it only reset when I stop switch off the car and starts the engine a gain plz help
