Can I order sample transmissions for quality evaluation before placing a bulk order?

We not only accept sample orders — we actively encourage them. A B2B importer who skips the sampling stage is taking an unnecessary risk, and we would rather you discover our quality level before you commit working capital to a full container. Our sample program is designed to be fast, cost-transparent, and technically supported so you can make a confident purchasing decision.

Sample Order Types and Pricing

For standard catalog transmissions, you can order 1 to 3 units of any single model at the sample-unit FOB price plus freight. The sample-unit price is higher than bulk pricing because it does not benefit from production-batch efficiencies — each sample unit is essentially a small-batch build — but we keep this premium reasonable because we view it as an investment in the relationship. For importers who want to evaluate multiple models simultaneously, we offer a multi-model evaluation pack: 1 unit each of 3 to 5 different models at a discounted combined sample price. This is popular with first-time buyers who need to assess which SKUs their workshops will order most frequently. For custom or OEM prototype samples, pricing is cost-plus-engineering-fee, quoted on a project-specific basis after technical review.

Sample Lead Time and Logistics

Standard catalog samples ship within 5 to 10 working days of confirmed P.O. and payment. Multi-model evaluation packs take 7 to 12 working days. We can ship samples via your nominated freight forwarder, or we can arrange door-to-door express freight through DHL, FedEx, or UPS for single units, or air freight for sample shipments of 3-5 units. The logistics method you choose depends on urgency versus cost — air express delivers in 3-7 days globally but costs significantly more than consolidated sea freight for a small pallet.

What to Inspect and Test

A transmission is not a commodity product where visual inspection alone is sufficient. We recommend a structured evaluation approach. Start with a thorough visual inspection: examine the casting surface finish for porosity or defects, check machining quality on mounting faces and sealing surfaces, verify that all threaded holes are clean and properly tapped, and confirm that the ID plate information matches your order. Next, perform a dimensional check using your technical drawing or an OEM reference unit — measure bell housing bolt patterns, input shaft dimensions, mount locations, and connector positions. Then install the sample unit on a test vehicle or dyno and evaluate shift quality across all gears, listen for abnormal noise under load and deceleration, and monitor for fluid leaks during and after the test cycle. Finally, disassemble one sample unit if your technical capability allows — inspect gear tooth contact patterns, clutch pack assembly quality, bearing preload, and internal cleanliness.

Technical Support During Evaluation

You are not on your own during the sampling phase. We provide a dedicated technical contact who can walk your mechanics through installation procedures via video call. Detailed installation manuals in PDF cover torque specifications, fluid type and fill quantity, TCU adaptation procedures where applicable, and common installation pitfalls to avoid. If any fitment or performance question arises during your evaluation, our technical hotline responds within 4 business hours via WhatsApp, WeChat, or email.

After Sample Approval — Locking the Standard

Once you approve the samples, we establish a golden sample process that protects both parties. One approved sample unit is sealed, signed, and retained in our factory's quality reference room. One identical unit is shipped to you with golden-sample documentation. Every future production batch is compared against this physical reference standard before shipment. This eliminates the risk of quality drift over time and gives you a contractual basis for rejecting any future shipment that does not match the approved sample quality. Bulk pricing takes effect from the first production batch following sample approval.
