Market analysis
How much does a used Infiniti QX80 transmission control module cost?
Asking prices for a used Infiniti QX80 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 25% premium over grade-C stock, with grade-A medians at $125.
Model year matters too: 2015 units carry the lowest median at $111, while 2025 tops the table at $300. Parts from 2009–2024 are interchangeable, so if the 2015 fits your vehicle, it offers the best value across 16 compatible years.
Against comparable vehicles, the Infiniti QX80 sits 7% below the Mercedes S Class ($135), 18% above the Mercedes E Class ($107), and 13% 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
- 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.
- Inspect connector pins for fluid wicking: Check harness plug sockets for fluid intrusion, as failing transmission harness seals push ATF into the TCM pins.
- 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.
- Confirm internal circuit board casing integrity: Check plastic housings for cracked mounting ears, housing cracks, or rattling components inside the module casing.
- 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.
