Market analysis
How much does a used Acura RDX transmission control module cost?
Asking prices for a used Acura RDX 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 42% premium over grade-C stock, with grade-A medians at $108.
Fitment variant moves the price more than most buyers expect. The most affordable variant we track, Network Gateway, (center dash), lists at a $71 median, while Body Control (BCM), (active control engine mount), ID 38800TJBAQ1 commands $365, a 414% gap inside the same part category. Confirm which variant your VIN requires before comparing quotes.
Model year matters too: 2017 units carry the lowest median at $100, while 2022 tops the table at $130. Parts from 2013–2022 are interchangeable, so if the 2017 fits your vehicle, it offers the best value across 10 compatible years.
Against comparable vehicles, the Acura RDX sits 20% below the Mercedes S Class ($135), 1% above the Mercedes E Class ($107), and 26% 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.
