TRANSWIN High Quality 5HP19 Automatic Transmission Oil Pump Cover for Audi A4 A6 A8 VW Passat
Product Description / Overview:
Permanently resolve front-end fluid leakage and safeguard your transmission’s hydraulic stability with the premium TRANSWIN High Quality 5HP19 Automatic Transmission Oil Pump Cover Assembly. In the legendary ZF 5HP19 (VW/Audi 01V) 5-speed longitudinal transaxle, the oil pump cover serves as both a structural fluid routing housing and the critical support hub for the torque converter neck. Under severe thermal stress, the original factory pump bushing frequently spins or melts out of its bore, catastrophically scoring the inner pump cover sleeve and destroying the front pump seal. Engineered using high-grade precision metallurgy, this heavy-duty aftermarket pump cover restores strict dimensional clearances, ensuring optimal oil pressure containment and seamless fluid flow into the main valve body circuit.
Key Product Features:
- Pre-Installed Heavy-Duty Bushing: Arrives with an upgraded, wear-resistant bimetal or bronze pump bushing pre-pressed into the center bore, offering superior thermal conductivity to prevent future seizure.
- Micro-Machined Seal Grooves: All internal fluid routing channels and the front oil seal lip seating area are finished to micro-metric tolerances, eliminating micro-gaps that cause pressure bleed-off.
- High-Density Anti-Warping Casting: Cast from low-porosity heavy aluminum alloy, this housing possesses high structural integrity to resist warping under cyclic bolt-torque stress and hot ATF pressure peaks.

⚠️ Rebuilder Technical Insight :
A catastrophic 5HP19 pump cover failure (where the bushing spins or melts out) is almost always a secondary symptom of a clogged or overheating torque converter torque lock-up system. When replacing this TRANSWIN pump cover, you MUST replace or professionally remanufacture the torque converter. Installing a brand-new pump cover onto a heat-distorted or debris-filled converter neck will instantly ruin the new inner bushing during the initial test drive. Additionally, always clean the auxiliary oil cooler lines to remove any trapped brass flakes or aluminum filings from the previous failure before turning the key.
