Tongyi Full-Compatible E-DCT Hybrid Transmission Fluid (e-DCTF)

Product Overview

Tongyi e-DCTF is a high-performance full-synthetic transmission fluid specially developed for new energy hybrid e-DCT dual-clutch transmission systems. Different from traditional DCT oil, this product integrates gear lubrication, clutch friction control, motor heat dissipation and electrical insulation protection. Adopting exclusive full-compatible hybrid formula and high-viscosity-index synthetic base oil with optimized ester components, it maintains stable viscosity across wide temperature ranges, effectively suppresses electrical signal interference, and provides comprehensive protection for integrated electric drive and mechanical transmission components. It is fully compatible with new energy hybrid e-DCT gearboxes and traditional wet DCT transmissions, realizing one fluid for multiple models.

Core Technical Advantages

  • Dual-scenario Full Compatibility: Compatible with new energy hybrid e-DCT electric dual-clutch transmissions and traditional fuel vehicle wet DCT transmissions, covering mainstream domestic and foreign DCT platform applications.
  • Professional Electric Drive Insulation Protection: Precisely controlled conductivity and dielectric constant, effectively insulating internal motor and electronic sensor components, avoiding electric corrosion and signal interference, adapting to integrated electric drive transmission working conditions.
  • Enhanced Gear & Bearing Anti-wear Performance: Optimized extreme-pressure anti-wear additive system forms stable high-strength oil film on gear and friction surfaces, reducing abrasion and impact wear during frequent shifting, extending transmission service life.
  • Stable Friction & Smooth Shifting: Precisely calibrated friction characteristics ensure consistent clutch locking performance, eliminate shifting jerk and lag, and improve overall transmission efficiency and driving comfort.
  • Excellent Wide-temperature Stability: Outstanding low-temperature fluidity ensures quick cold start response; excellent high-temperature shear stability and oxidation resistance prevent oil deterioration, sludge and carbon deposition under long-term high-load operation.

Application Scope

Suitable for new energy hybrid vehicles equipped with e-DCT electric dual-clutch transmission systems, compatible with VW Golf GTE DQ400E and other mainstream new energy DCT specifications. Also applicable to all traditional fuel vehicles with wet DCT dual-clutch transmissions.

Packaging & Storage

Standard Package: 1L plastic bottle Shelf Life: 36 months (unopened, stored in cool and dry environment) Storage Conditions: Store indoors at 0°C ~ 40°C, keep containers tightly sealed, avoid direct sunlight, freezing and high-temperature exposure.

Important Notes

Do not mix with ATF, CVT, dry DCT or ordinary gear oil. Replace fluid strictly in accordance with vehicle maintenance manual. For official TDS and MSDS documents, please contact Tongyi business department.
