3. Inspection & Testing Standard

Every raw material batch is inspected before production. Friction plates use premium paper-based friction material and are tested through continuous high-temperature friction cycles to maintain a stable friction coefficient and anti-fade performance under heavy load. Steel plates are quenched and tempered, then checked for flatness, surface finish and Rockwell hardness to avoid deformation or warping after long-term operation. All oil seals and O-rings are made of high-temperature fluororubber and tested for ATF compatibility, anti-aging and compression resistance. Our QC team verifies each gasket, plate and seal one by one against official OE drawings to confirm correct quantity and dimensions. Random sample bench tests are conducted to check clutch engagement smoothness and sealing reliability. Each kit is marked with a batch number for traceability, and defective parts are removed before packing.

4. Core Competitive Advantages

Complete master overhaul kit including friction plates, steel plates, gaskets, oil seals and O-rings for full transmission rebuild. Upgraded friction material with excellent heat dissipation to reduce slipping risk during frequent shifting and heavy load use. Laser precision cut gaskets with accurate OE contour to help prevent oil leakage after overhaul. Factory direct supply with competitive wholesale pricing for distributors and transmission rebuild shops. Strict OE dimensional standards ensure direct replacement without modification. Stable stock availability supports fast packing and shipment for urgent repair orders. Free VIN matching service helps confirm the correct version before order and reduces fitment mistakes. Private label packaging is available for B-end customers who want to build their own brand.

5. Professional Installation Guidance

Before installation, confirm the transmission code is TG-81SC and verify the vehicle VIN to exclude incompatible sub-models. Fully drain the old ATF fluid, completely disassemble the gearbox, and thoroughly clean the housing, valve body, oil channels and oil cooler to remove metal debris from worn components. Replace all friction plates, steel plates and sealing parts in this kit together; mixing new parts with old seals or old plates may cause oil leaks or shifting faults. Tighten all bolts strictly according to the torque values in the official service manual. After assembly, fill with the specified ATF oil, complete transmission adaptive learning reset and perform a road test. Do not operate the vehicle under heavy load immediately after rebuild. If abnormal codes or slipping occur after installation, contact our technical team for remote support.

6. Packaging & Transportation

Friction plates and steel plates are fixed separately on moisture-proof anti-slip backing boards. Gaskets, oil seals and O-rings are sealed in oil-resistant transparent plastic bags. All components are then packed into export cartons with shockproof foam padding to avoid extrusion damage. The outer carton is printed with the Transmesun brand, TG-81SC transmission model and cross reference part numbers.

8. FAQ

Q1: What is the difference between the standard version and the heavy-duty upgraded version of this TG-81SC overhaul kit, and what scenarios should each version be used for?

A: Our standard TG-81SC overhaul kit adopts original OE specification friction plates, steel plates and sealing components, which perfectly matches the original design torque limit. It is suitable for regular passenger vehicles with normal driving habits and mileage below 180,000 km, such as daily commuting family cars. The heavy-duty upgraded version uses upgraded ceramic-based friction material, thicker quenched steel plates and high-performance FKM fluororubber seals. It can withstand higher continuous torque and stronger heat resistance, ideal for vehicles with frequent towing, mountain driving or high mileage over 200,000 km. We recommend wholesalers introduce the heavy-duty version to repair shops that focus on high-load vehicle maintenance, as it effectively reduces rework rates and improves end-customer satisfaction. We can supply both versions in mixed orders to help you enrich your product portfolio.

Q2: Can you provide material certificates and test reports for customs inspection and local market compliance review in our country?

A: Yes, we can supply a full set of supporting documents for your customs clearance and local compliance audit. The documents include material certification of friction plates, steel plates and rubber seals, raw material test reports, batch inspection records from our QC laboratory, commercial invoice, packing list and certificate of origin. All test data is based on international auto parts industry standards, and the reports are issued in English. Many of our wholesale partners in Europe, North America and Southeast Asia have used these documents smoothly for customs spot checks and local market regulatory reviews. Please inform our sales team in advance when placing orders, and we will arrange these documents together with your shipment or send them to you by email separately.

Q3: If some parts of the overhaul kit are out of stock, can we arrange separate shipment for available items and send the rest later? What is the charge rule for split delivery?

A: We support split shipment for orders with partial stock shortage. Once we confirm which items are ready, we will pack and deliver the available parts first, and arrange the remaining goods as soon as production is finished. For regular wholesale customers, we will not charge extra handling fees for split shipments. However, you need to note that each separate consignment will generate independent freight cost if you choose air freight or express delivery. If you select sea freight, we suggest waiting for full stock to combine into one shipment to save logistics cost. Our sales team will clearly inform you of stock status, estimated ready date and freight difference before we confirm split delivery, so you can make the final decision according to your downstream repair shop’s urgent demand.
