How to diagnose and fix P0810: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Kia Forte · 2019–2024
The Forte GT (and GT-Line with the 1.6L Gamma T-GDI) uses the D7UF1 seven-speed dry dual-clutch transmission rather than the IVT used on 2.0L cars. The dry clutch friction material glazes and the clutch actuator adaptation drifts, producing a body-shaking judder when creeping away from a stop or in slow traffic - the car vibrates but the steering wheel does not, which is the diagnostic that distinguishes clutch judder from a wheel/tire imbalance. As it progresses owners report a loud thud/jerk on the 1-2 engagement and, under wide-open throttle around 30-40 mph, a downshift where revs flare without corresponding acceleration (clutch slip). Kia issued TSB TRA083 covering 2016-2020 7-speed DCT vehicles.
Common Symptoms
- Vehicle shudders/vibrates when pulling away from a stop
- Loud thud and jerk on low-speed shifts
- Revs flare without acceleration under hard throttle
- Hesitation or lurching in stop-and-go traffic
- Clutch/transmission overheat warning message
How to Fix
Per the Kia bulletin, confirm judder with the creep test (drive at up to about 3 mph from a stop; body vibrates, steering wheel steady). First step for milder cases is a TCU software upgrade with a clutch touch-point/actuator re-learn. If judder persists, the dual clutch assembly must be replaced and the TCU reflashed afterward. Replacement is normally covered by the 10yr/100k powertrain warranty for the original owner, or 5yr/60k for subsequent owners. Do not simply add or change fluid to chase judder - the D7UF1 clutch pack is dry and the failure is friction-surface, not fluid, related.

Renault Clio · 2013–2019
Clio IV models with the six-speed EDC automatic (the dry-clutch Getrag DCT250, the same family as the troubled DSG/PowerShift units) suffer low-speed judder, jerky 1st-2nd shifts, clunks engaging Drive or Reverse, overheating warnings in traffic, and 'Check auto gearbox' messages. Causes range from TCU (transmission control unit) software and module faults — which Renault addressed on some cars — to worn dry-clutch friction surfaces and slow actuators. One documented Clio RS 200 EDC failure drew a quote of about $4,500 for the clutch pack alone.
Common Symptoms
- Judder or shudder when pulling away
- Jerky low-speed gearshifts around town
- 'Check auto gearbox' warning message
- Clunking when engaging Drive or Reverse
- Gearbox overheating warning in stop-start traffic
How to Fix
First step is a dealer software update with clutch touch-point relearn and adaptive reset, which cures many judder complaints; TCU replacement fixed others under Renault goodwill. Worn clutch packs or mechatronic faults require replacement of the clutch pack or repair of the mechatronic unit at a gearbox specialist.

Kia Soul · 2017–2020
Souls with the 1.6L Turbo-GDI and 7-speed dry dual-clutch transmission exhibit low-speed clutch judder (a body shake accelerating from a stop, worst on cold/humid mornings), harsh engagement, and hesitation. The dry clutches glaze/wear during stop-and-go creeping. Kia's diagnosis is a creep-driving test: if the body vibrates without steering-wheel shudder, it is clutch judder. TSB TRA083 first applies a TCU anti-judder logic update, then replaces the dual-clutch assembly if hardware is glazed/worn.
Common Symptoms
- Shudder/judder accelerating from a stop
- Harsh or delayed shifting
- Hesitation and slipping in traffic
- Morning shudder after rain
How to Fix
Kia creep-test diagnosis; first step is a TCU/software anti-judder logic update via KDS, then dual-clutch assembly replacement per TSB TRA083 if judder persists.
