If you’re behind the wheel of a heavy-duty truck, there’s a good chance you’ve come across the ZF AS Tronic transmission. Built for power and efficiency, it’s one of the most widely used automated manual transmissions in commercial fleets across the U.S. But even the toughest transmissions need attention—and when they start acting up, time

  If you drive a vehicle equipped with a TC Tronic transmission, you’re behind the wheel of a smart system designed for performance, control, and smooth shifting. But like any transmission, it’s not bulletproof. And when something starts to go wrong, the sooner you recognize the signs, the better chance you have at avoiding a

If you’ve ever ridden a city bus that didn’t jolt with every gear change, there’s a good chance you’ve experienced the smooth operation of a ZF Ecolife transmission. It’s the workhorse behind countless transit buses, coaches, and heavy-duty commercial vehicles across North America. But while this transmission is designed for long-haul durability and performance, ZF

If you’re looking up how to check transmission fluid on forklift, it usually means one thing—something’s not working the way it should. Maybe the forklift is hesitating when shifting. Maybe you’re hearing a noise you shouldn’t be hearing. Or maybe you’re just trying to stay ahead of a costly repair. Whatever the reason, you’re in

Precision Transmission has been a ZF Off-Highway distributor for decades, which means we carry OEM-level parts access, factory documentation, and software support that most shops calling themselves a ZF transmissions dealer simply don’t have. That distinction matters more than it sounds — a ZF unit that’s misdiagnosed or serviced with the wrong procedure doesn’t fail

A transmission that’s slipping, hunting for gears, or throwing a fault code doesn’t fix itself, and running it another shift usually turns a contained problem into a torn-up gearset or a scored input shaft. Heavy-duty transmission diagnostics is how we find out which one it is before that happens — not a guess based on

A concrete mixer transmission slipping under load doesn’t wait for a convenient time to fail. It shows up mid-pour, with a full drum turning slower than it should and a crew standing around a truck that needs to keep moving. That’s a different problem than a piece of equipment parked in a yard — a

When a crane, loader, or transit bus is down waiting on a transmission part, every extra day on the shelf is a day that unit isn’t earning. Sourcing decisions made under that pressure — grab the cheaper aftermarket part now, or wait on a factory-direct OEM order — are exactly how fleets end up with

A stalled excavator on a job site isn’t just an inconvenience — it’s a crew standing around, a schedule slipping, and every other piece of equipment staged around it sitting idle too. More often than operators expect, the cause traces back to the excavator transmission rather than the engine: a hydrostatic pump losing pressure, a

A wrong part on a ZF Ecomat, Traxon, or AS Tronic unit doesn’t just cost you the part. It costs you the machine sitting idle while a return gets processed, a fleet manager rescheduling a job, or a crane or wheel loader earning nothing on a site that’s paying by the day. That’s why the

When a heavy-duty transmission fails, the real cost isn’t the repair invoice — it’s the truck, bus, crane, or piece of construction equipment sitting idle while a route, job site, or contract waits. What goes back into that unit determines how long it stays fixed. OEM transmissions — units built or authorized by the original

A parts order pulled for the wrong bus transmission costs more than a returned box. It means a bus sitting in the yard while the correct unit gets sourced, a route covered by a spare that wasn’t budgeted for that week, and a technician who diagnosed the problem correctly but ordered against the wrong assumption.
