Product Overview

What this part is — and why it fails.

The U340 is the Aisin (Toyota) 4-speed automatic fitted to Toyota Corolla, Avensis. This page covers the torque converter & housing for that platform, supplied by Guangzhou Meishun (TRANSMESUN) — a CE-certified remanufacturing factory in Huadu, Guangzhou, with 20 years in the transmission trade.

Compact Toyota 4AT; overhaul kits and friction sets are the steady items. That failure chain is exactly what our process is built around: the part is inspected against the platform's documented wear points. Converters are welded-verified and leak-checked; rotation and lock-up surfaces inspected per unit. Every order is verified against your transmission code before anything ships.

Use Cases

Who orders this part, and why.

Shudder complaints

Lock-up shudder at light throttle usually points at the converter clutch surface — replacing the converter during the valve-body job prevents the comeback.

Rebuild programs

Cut open, clean and re-weld — or supply new — matched by code.

Distributors

Converters ship flat-packed volume-friendly; failure-leader codes are core stock.

Applications & Fitment

Which vehicles this platform serves.

Typical applications for this platform. Always confirm against the transmission code — one car line can carry two different units by year and market.

Buyer FAQ

Questions buyers actually ask.

New or remanufactured converters?

Both. Remanufactured units are cut open, cleaned, re-clutched and re-welded; new units suit high-turn codes.

How do I match a converter?

By transmission code and, where visible, the converter's stamped OE number. Send both if you can.

Do you supply planetary gear sets too?

Yes — planetary sets, one-way clutches, housings and oil coolers are all catalog categories.

How do I verify this part matches my Aisin unit before ordering?

Send the transmission code from the nameplate (or a photo of it). Our engineers confirm the generation and variant in writing before anything is packed — this removes the generation-mismatch risk that plagues this platform.

What are the ordering terms?

MOQ starts at one piece, lead time from 1 day for in-stock codes, 12-month quality guarantee across all product categories, export-grade packing with shipment photos.
