Market analysis
How much does a used Buick Regal transmission control module cost?
Asking prices for a used Buick Regal 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 37% premium over grade-C stock, with grade-A medians at $103.
Fitment variant moves the price more than most buyers expect. The most affordable variant we track, Body Control (BCM), (LH dash), lists at a $50 median, while Memory, (seat, mounted under seat), ID 13517130 commands $176, a 252% gap inside the same part category. Confirm which variant your VIN requires before comparing quotes.
Model year matters too: 2018 units carry the lowest median at $86, while 2016 tops the table at $177. Parts from 2013–2026 are interchangeable, so if the 2018 fits your vehicle, it offers the best value across 14 compatible years.
Against comparable vehicles, the Buick Regal sits 26% below the Mercedes S Class ($135), 7% below the Mercedes E Class ($107), and 31% 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.
