The PT2529 is the Volvo PowerTronic transmission for the G-series articulated haulers — the A35G, A40G, and A45G. It is the larger-capacity unit, built for the higher gross vehicle weight of the A45G, and is not interchangeable with the PT2519. Midwest Industrial Sales rebuilds it under part number 22443. Every unit is dyno-tested under load before it ships, and carries a 2-year warranty.
The PT2529 is the production transmission across the G-series Volvo articulated haulers in the 35-, 40-, and 45-tonne weight classes. Midwest Industrial Sales rebuilds and stocks it under part number 22443.

After 20+ years of rebuilding PT-series transmissions, these are the failure modes we see most often. Every Midwest Industrial Sales rebuild addresses each of them as part of the standard process — not just the failed component that brought the unit in.
Most often traced to worn clutch frictions and degraded steels. Severity grows under high-cycle loaded haul-road duty on the heavier G-series machines.
The torque converter lock-up is a known wear point — fluid contamination from upstream wear accelerates the failure.
Main pressure solenoids and fluid sensors fail in dusty haul-road environments. Often shows up as ECM fault codes before drivability complaints.
Reduced lube flow is the root cause of most premature transmission failures. By the time the operator notices, the damage is already cascading.
High-cycle articulated-truck operation wears the planetary carrier package — every Midwest Industrial Sales rebuild addresses it whether or not it was the presenting failure.
Every PT2529 that leaves Gardner, Illinois has been torn down to housing castings, cleaned, inspected against factory specs, and reassembled with new wear parts. Carlisle frictions and steels on every clutch pack, genuine Volvo OEM solenoids and sensors, an updated planetary carrier package, and a new higher-volume charge pump. The completed unit runs on our dynamometer under load to verify every clutch pack is within factory specification. It does not ship until it passes.

Midwest Industrial Sales rebuilds it under part number 22443. The same transmission also covers the A35G and A45G articulated haulers.
The A45G uses the PT2529 — the larger-capacity transmission designed for the A45G’s higher gross vehicle weight. It is shared across the A35G, A40G, and A45G G-series trucks. Midwest Industrial Sales rebuilds it under part number 22443.
The PT2519 fits the A35E/F and A40E/F generations. The PT2529 is the larger-capacity transmission used in the A35G, A40G, and A45G — designed for the higher gross vehicle weight of the A45G. They are not interchangeable. Midwest Industrial Sales rebuilds and stocks both.
