P0732 on Jeep
Gear 3 Incorrect Ratio
P0732 on Jeep vehicles indicates gear 3 incorrect ratio. Au7o has documented this code across 1 Jeep model — most commonly on Wrangler. This code means the transmission control module detected that the gear ratio in 3rd gear does not match what it expects when the transmission is commanded into that gear. The computer compares input (turbine) speed to output shaft speed; if the math for 3rd gear is wrong, it sets this code. It usually points to internal slipping or a hydraulic/electronic control fault rather than a sensor reading error. Typical repair costs on Jeep range from $150 to $1,500, depending on the specific model and root cause.
Common Causes of P0732
- •Low or dirty/degraded transmission fluid
- •Worn clutch packs or friction material in 3rd gear circuit
- •Faulty shift solenoid for 3rd gear
- •Valve body or pressure control problems
- •Internal mechanical wear or damage in the transmission
- •Clogged transmission filter restricting flow
- •Faulty input/output speed sensor giving skewed data

Jeep Wrangler(1 issue)
- 42RLE 4-Speed Automatic Torque Converter Shudder (TSB 21-001-08)2007-2011
JK Wranglers with the 42RLE 4-speed automatic exhibit a torque-converter-clutch (TCC) shudder felt as a steady-state vibration or shimmy, typically during light throttle/partial converter lockup and most noticeable when the transmission is at moderate operating temperature. Chrysler acknowledged the condition in TSB 21-001-08 (later revisions), which addresses TCC shudder and shift-quality concerns (1-2, 2-3, 3-4 upshift bumps) and DTC P0732. The shudder stems from the converter clutch lining/fluid interaction and TCM calibration; left unaddressed it can progress to harsh shifts.

What does P0732 mean on Jeep?▼
P0732 stands for "Gear 3 Incorrect Ratio." This code means the transmission control module detected that the gear ratio in 3rd gear does not match what it expects when the transmission is commanded into that gear. The computer compares input (turbine) speed to output shaft speed; if the math for 3rd gear is wrong, it sets this code. It usually points to internal slipping or a hydraulic/electronic control fault rather than a sensor reading error. On Jeep specifically, this code is documented across 1 model.
