Market analysis
Why does the Lexus NX300 transmission control module cost more?

Supply also plays a role: Mercedes C Class has 17,328 priced listings versus 2,723 for Lexus NX300, 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 4 for the Lexus NX300 (2018–2021), so the Mercedes C Class data reflects a broader range of generations.

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.
