Fort Lupton, Colorado - July 22, 2026 -
Colorado Transmission & Diesel Specialists has formalized a priority scheduling arrangement for commercial fleet customers in Greeley, Colorado, aimed at reducing the downtime that keeps work trucks off the road. The decision reflects how the shop has chosen to structure its fleet work around the operator's cost of an idle vehicle.
Colorado Transmission & Diesel Specialists provides fleet maintenance in Greeley, Colorado, covering preventative maintenance schedules and bumper-to-bumper diagnostics for the contractor, agricultural, and oilfield work trucks common across Weld County. The shop's position is that a work truck off the road is lost income for its operator, and that scheduling should be built around that reality. Fleet operators in the area often run a mix of vehicles of different ages and duty cycles, which makes a coordinated maintenance plan more useful to them than ad hoc repair.

In practice, the arrangement means fleet vehicles are moved up the queue and worked into planned maintenance intervals rather than waiting for a breakdown to force the issue. Preventive schedules are designed to catch wear before it becomes a roadside failure, and routine servicing is coordinated so that a fleet's vehicles are not all due at once. The aim is to keep as much of an operator's fleet available as possible at any given time.
Bumper-to-bumper coverage is part of how the shop keeps that promise. Rather than addressing one system in isolation, fleet servicing takes in the drivetrain, brakes, fluids, and general condition of a vehicle in a single visit, so issues are caught together rather than across repeated trips. A problem found early during scheduled maintenance is usually cheaper and quicker to resolve than the same problem found at the roadside.
A single shop handling both routine maintenance and specialist repair is part of the appeal for fleet operators. The same premises that service brakes, fluids, and upkeep also carry out in-house transmission and diesel work, including the Allison Transmission drivetrains found in heavier trucks, so an operator is not routed between a general garage and a specialist for different problems. Computerized diagnostics are used to confirm a fault before a repair is recommended, which keeps fleet repair costs tied to confirmed causes rather than guesswork.
"A work truck sitting in our bay overnight is a day that operator isn't earning with it, and we take that seriously," said Doug Friedlan, owner of Colorado Transmission & Diesel Specialists. "Priority scheduling is our way of saying fleet customers get worked in fast and kept on a plan, so we're catching things before they put a truck out of action. Having the transmission and diesel work in-house means they're not chasing two shops either."
The work trucks the shop sees across Weld County tend to earn their keep the hard way. Many tow heavy loads, climb grades, and put on long daily mileage across the agricultural and oilfield operations of the Greeley area, which wears drivetrains and diesel systems faster than ordinary commuting does. Trucks running that kind of duty cycle benefit most from being kept on a maintenance interval, because the failures that take them off the road are often the ones that build up slowly and could have been caught.
"These trucks work for a living, and they show it," Friedlan added. "When something tows and climbs all day, every day, you don't wait for it to break. You stay ahead of it with a schedule, and that's what keeps a fleet running and an operator paid."
By structuring fleet work around scheduling and prevention, the shop frames its service around keeping commercial vehicles available across the Greeley area and the wider county. For operators whose income depends on those vehicles, availability is the measure that matters most. Updates on the shop's fleet and commercial work are posted to its Facebook page, and further information about its fleet maintenance services is available at the company website.
