Used 7DCT220 Transmission Gear Shift Fork OE 1702025BA6K for Bestune T77 1.2T

This used 7DCT220 gear shift fork assembly matches Bestune T77 equipped with 1.2T turbo engine and 7DCT220 wet dual clutch transmission, corresponding OE numbers 1702025BA6K,1702020BA6K,1702030BA6K,1702040BA6K. Every shift fork undergoes strict visual inspection, wear measurement and sliding test. We eliminate deformed, excessive worn units to avoid gear selection failure. It solves common faults such as difficult gear engagement, jumping out of gear and abnormal shifting noise during DCT overhaul.

1. Appearance inspection: Check fork body for cracks, impact deformation and bending.
2. Wear measurement: Measure sliding contact surface thickness; reject units beyond wear limit.
3. Sliding test: Verify smooth movement without jamming or excessive clearance.
4. Cleaning: Remove oil sludge and metal debris to prevent secondary abrasion inside gearbox.
5. Classification: Mark different OE codes clearly to prevent mixing different shift forks.

• Strict Pre-shipment Inspection

All shift forks pass wear and sliding test before shipment, effectively lowering after-installation failure risks.

• OEM Exact Dimension

Consistent with original mounting size and sliding stroke, no modification required during assembly.

1. Clean gearbox internal shaft and sliding rail thoroughly before installing shift fork.
2. Check synchronizer ring condition simultaneously; worn synchronizer will still cause shifting failure after fork replacement.
3. Assemble shift fork in correct position corresponding to each OE code, avoid wrong installation leading to gear disorder.
4. Fill specified DCT fluid after assembly, then conduct road test to verify smooth gear selection without abnormal noise.

Q1: Inside one 7DCT220 gearbox, four shift forks with different OE numbers serve separate gears. They differ in shift travel and mounting pivot. Can these forks be interchanged during assembly?

A1: Mutual replacement is not allowed. Each OE number corresponds to fixed gear position with exclusive travel and pivot structure. Random swapping will lead to difficult gear engagement, jumping out of gear and abnormal noise. Please confirm the exact gear position and OE code before ordering. We will strictly match the correct fork according to your vehicle information to avoid overhaul failures for local repair shops.

Q2: What is the unit price gap between single sample order and bulk order of 120 pieces? How many pieces do we need to purchase at a time to enjoy tiered big customer bottom price?

A2: There is an obvious price gap. The unit price for 120pcs bulk order is about 15% lower than single sample price. Our preferential big customer price threshold starts at 180 pieces per order. Larger order quantity brings deeper discount. For long-term wholesale partners with annual contracts, we can offer more competitive prices to expand your profit space in local aftermarket.

Q3: Orders surge during overseas auto parts sales peak. Can you reserve inspected qualified stock for long-term stable wholesale partners to prevent stockouts?

A3: Yes, we can reserve dedicated stock for our long-term cooperative wholesale clients. You just need to share your estimated monthly demand in advance. We will allocate pre-tested 7DCT220 shift forks and guarantee stable supply in busy seasons. Meanwhile, we offer tiered favorable pricing for cyclic orders, effectively supporting your continuous business operation in local aftermarket markets.
