Supply also plays a role: Mercedes E Class has 27,703 priced listings versus 8,415 for Cadillac XT5, and more listings generally mean more choices and more competitive pricing.
Grade A (excellent condition) parts make up 91% of Mercedes E Class listings compared to 64% for the Cadillac XT5, so buyers looking for top-condition units will find more options on the Mercedes E Class side.
The Mercedes E Class average ($127) runs 19% above its median ($107), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.

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.
