Market analysis

How much does a used Infiniti Q50 transmission control module cost?

Asking prices for a used Infiniti Q50 transmission control module are unusually spread out: the top listing asks more than ten times what the cheapest does, so which unit you pick matters more than the median. Condition matters: grade-A units (lowest mileage, best condition) carry roughly a 1% premium over grade-C stock, with grade-A medians at $101.

Model year matters too: 2016 units carry the lowest median at $100, while 2023 tops the table at $126. Parts from 2011–2023 are interchangeable, so if the 2016 fits your vehicle, it offers the best value across 13 compatible years.

Against comparable vehicles, the Infiniti Q50 sits 25% below the Mercedes S Class ($135), 6% below the Mercedes E Class ($107), and 30% below the Mercedes GLE Class ($145) for the same part. The “similar vehicles” cards below open each comparison guide.

Buying a used transmission control module: what to check

  1. Match exact part numbers and software flash codes: Verify hardware numbers and firmware revision suffix letters, as valve body solenoid drivers vary between sub-models.
  2. Inspect connector pins for fluid wicking: Check harness plug sockets for fluid intrusion, as failing transmission harness seals push ATF into the TCM pins.
  3. Verify donor axle ratio and tire size match: Ensure donor vehicle axle ratios and tire sizes match to prevent shifting fault codes and limp-mode triggers.
  4. Confirm internal circuit board casing integrity: Check plastic housings for cracked mounting ears, housing cracks, or rattling components inside the module casing.
  5. Perform adaptive shift learn routine after install: Clear existing TCM adaptive tables using a scan tool so the module relearns your transmission's clutch pack wear.
