Market analysis

Supply also plays a role: Mercedes S Class has 32,212 priced listings versus 4,070 for Kia Forte, and more listings generally mean more choices and more competitive pricing.
The Kia Forte average ($126) runs 20% above its median ($105), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
At Grade A (excellent) condition, the Kia Forte is 26% cheaper ($107 vs $144) — the gap narrows 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.
