Market analysis

Supply also plays a role: Mercedes C Class has 17,328 priced listings versus 971 for Land Rover Defender, and more listings generally mean more choices and more competitive pricing.
The Mercedes C Class average ($121) runs 21% above its median ($100), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 11 model years for the Mercedes C Class (2015–2025) but only 6 for the Land Rover Defender (2020–2025), so the Mercedes C Class data reflects a broader range of generations.
The Mercedes C Class transmission control module is interchangeable across 17 model years versus just 12 for the Land Rover Defender — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the Mercedes C Class is 49% cheaper ($106 vs $206) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used transmission control module
- Match OEM hardware and software part numbers exactly, as shift schedules and solenoid driving algorithms differ between gear ratios and engine sizes.
- Determine if the module is standalone, integrated into the PCM/ECM, or mounted internally on the transmission valve body (mechatronic unit).
- Check if the module requires VIN programming, clutch adaptation relearns, or flash updating before normal gear engagement will occur.
- Inspect connector pins for fluid wicking; leaky transmission harness seals can force transmission fluid up into the TCM connector plug pins.
