Product Description

OB5

Advantages and Compatible Models of OB5 Transmission
Technical Overview
Type: 7-speed wet dual-clutch transmission (Wet DCT).
Torque Capacity: Up to 550 N·m.
Structure: Features two wet clutches (K1 and K2):K1 controls gears 1, 3, 5, 7.
K2 controls gears 2, 4, 6, and reverse.
Control System: Hydraulically operated by the Transmission Control Module (TCM), managing clutch engagement and shift forks via solenoids.
Key Advantages
Lightning-Fast Shifting
Shifts complete in milliseconds without interrupting power flow, delivering seamless acceleration—ideal for performance driving.
Example: Downshifting from 7th to 4th gear in sport mode takes <0.3 seconds.
High Torque Capability
With a 550 N·m capacity, it pairs perfectly with high-output engines (e.g., Audi's 2.7L V6 twin-turbo in the S4 B5).
Exceptional Efficiency
Wet clutch design minimizes power loss compared to torque converter-based ATs, improving fuel economy by up to 10% in highway driving.
Adaptive Driving Modes
Supports:Comfort Mode: Smooth shifts for daily use.
Sport Mode: Aggressive shifting with delayed upshifts.
Manual Mode: Paddle-shift control for track or spirited driving.
Durable Wet Clutch Design
Oil cooling prevents overheating during prolonged high-load use (e.g., towing or track days), outperforming dry DCTs in thermal management.

Comparison with Other Transmissions
vs. 02E (DQ250):
OB5 offers a 7th gear for lower highway RPM (improving fuel efficiency) and higher torque capacity (550 N·m vs. 350 N·m), while 02E is optimized for compact performance cars (e.g., Golf R).
vs. ZF 6HP AT:
