What Does P07B0 Mean?
Transmission friction element "H" is not engaging properly or is stuck in the released position. The TCM has detected that this clutch pack or band fails to apply with sufficient force when commanded. Element H is typically one of the higher-numbered elements in advanced multi-speed transmissions (8-speed, 10-speed, etc.) and its failure affects specific gear ratio combinations. The vehicle may experience slipping, flare shifts, gear hunting, or limited gear availability.
Safety Warning
Driving is not recommended. A slipping friction element can fail completely without warning, leading to sudden loss of drive. The transmission may enter limp mode with severely limited performance. Have the vehicle towed.
Common Causes
35%
Worn or burnt friction element H clutch pack with depleted friction material
25%
Insufficient hydraulic pressure at element H servo from valve body degradation or restricted passages
20%
Defective control solenoid for element H apply circuit
12%
Leaking servo piston seals reducing effective apply pressure
8%
Low or degraded transmission fluid affecting overall hydraulic system performance
Diagnostic Steps
1
Check transmission fluid level and condition — burnt smell, dark color, or visible debris particles indicate internal wear.
2
Monitor scan tool gear ratio data during all shift events to identify which transitions show slipping when element H should be applied.
3
Perform hydraulic pressure testing at element H's circuit test port under various load and RPM conditions.
4
Execute solenoid output tests via scan tool to verify element H control solenoid operates within specifications for resistance and actuation.
5
Remove transmission pan to inspect for friction material accumulation, metallic debris, and overall fluid contamination level.
