Remanufactured VT1 CVT Transmission With New Reinforced Push Belt For Fixing Shudder Slipping Ratio Faults Mini R50 R52 Rover MG BYD F3 G3 L3 VT1 27 FWD CVT Gearbox

1. Product Overview This remanufactured VT1 CVT transmission assembly is optimized to solve the most frequent VT1 CVT hydraulic and mechanical faults, including steel belt wear, pulley surface scuffing, pressure loss, shudder during acceleration, slipping and ratio error fault codes. Every unit is fully disassembled, deep cleaned, pulley surface inspected and polished. The old push belt is replaced with a brand-new heavy-duty belt, all internal sealing components are upgraded to high-temperature FKM fluororubber to resist CVT fluid aging and high heat. This unit is pre-calibrated on CVT dyno bench, ready for direct replacement for repair shops focusing on classic MINI, Rover, MG and BYD CVT repair. It is a cost-effective alternative to expensive brand new OE VT1 transmission.

3. Inspection & Testing Standard Our remanufacturing inspection standard for VT1 CVT focuses on stability and anti-shudder performance. After ultrasonic cleaning, technicians inspect pulley taper surface for scoring and wear. All worn bearings, seals and solenoids are replaced. The new push belt is installed with precise tension adjustment. After assembly, dynamic dyno test runs multiple pressure and speed cycles to simulate city stop-and-go and highway cruise conditions. We record pressure curves and ratio change data for every unit. Any unit with unstable pressure, belt slip or internal leakage will be rejected and reworked before packing.
4. Core Competitive Advantages Equipped with brand-new upgraded push belt, the core part that causes most VT1 shudder and slipping complaints. Full dyno cycle test data saved for each unit, easy for your downstream repair shops to verify and check. All aging solenoids and sealing rings are renewed, not reused old parts, greatly cut rework rate on classic VT1 CVT repairs. Supports bulk wholesale and small trial order, flexible MOQ for new distributors. We can supply matching VT1 overhaul kits, filters and oil coolers as supporting spare parts. Free fault diagnosis guide and installation notes are provided for your repair team. Neutral packing without factory logo for your resale business.
5. Professional Installation Guidance Before fitting this VT1 CVT assembly, confirm the root cause of failure. If the pulley taper surface is severely damaged, replacing only the transmission may not fully resolve the shudder problem. Replace the CVT filter and gaskets, and fully flush the oil cooler to remove all metal particles. Check the wiring harness connector for water intrusion and corrosion. After installation, use professional scanner to reset CVT adaptive values and perform relearn procedure. Avoid heavy load driving within the first 80km after rebuild. If shudder still appears after installation, check oil quality and cooler flow first. Our engineers can help you analyze DTC codes and pressure logs remotely.
6. Packaging & Transportation Each VT1 gearbox is protected by anti-rust oil film and custom thick foam cushion, fixed inside a sturdy export wooden crate to prevent impact damage during transit. Desiccant packet is placed inside crate to prevent oxidation under humid marine environment. Outer crate is marked with clear part number and batch information. We can print your own brand shipping marks on crates for bulk orders. We support EXW, FOB and CIF quotation terms. All required export documents including dyno test report can be provided to match your local customs requirement.

8. FAQ 

A1: The oil cooler system is the biggest hidden danger for secondary damage to the VT1 CVT. Before installation, your repair partners must fully flush the oil cooler and all connecting oil lines to remove fine metal debris, carbon sludge and old degraded CVT fluid left by the failed original gearbox. They also need to test the cooler flow rate and check for internal blockage or leakage. If the cooler is clogged, heat cannot be dissipated effectively, and high temperature will accelerate the aging of the new push belt, seals and solenoids. Metal particles trapped inside the cooler will circulate into the newly rebuilt transmission, scratch the pulley taper surfaces and cause slipping again within a short mileage. We always remind our wholesale clients to sell matching VT1 filters and cooler service kits together with the transmission assembly. This bundled solution helps your local repair shops reduce comeback rates and build a better reputation among end vehicle owners.

A2: Yes, we offer full private label support for qualified B-end wholesale distributors. Our default VT1 units are neutral without our factory logo, which is ready for your own branding. For custom packaging, we can print your brand name, barcode, part number and warning information on export wooden crates and inner labels. Our MOQ for custom branded packaging is 300 units, and the lead time is roughly 15 working days after you confirm the final artwork. Beyond packaging, we can provide high-resolution product photos, technical datasheets, fault introduction copy and SEO-friendly product descriptions for your independent website, social media and local offline catalogs. We will strictly protect your brand information and never share your branding materials with other clients. We also keep all test reports under your brand reference if you need them for local market promotion or customs submission.

A3: We fully support mixed wholesale orders combining VT1 CVT assemblies, matching overhaul kits, CVT filters, oil coolers and spare solenoids. Consolidating all goods into one single shipment helps you cut down international freight cost compared with separate parcels. Inside the export wooden case, we use solid partition boards to separate heavy transmission assemblies from small accessory kits, preventing collision damage during transit. Every SKU gets an individual sticker printed with OE part number, product name, quantity and batch code. We also attach a detailed packing list which lists every item, gross weight and dimension for your warehouse receiving inspection. If you need to split certain urgent items into a separate advance shipment, just inform our sales team before order confirmation, and we will calculate the extra freight cost for your approval. This flexible mixed order policy helps you enrich your CVT repair spare parts inventory without placing multiple separate orders.
