About Atec Trans-Tool

When transmission professionals need tools they can count on, Atec Trans-Tool has been the answer for decades. Based in San Antonio, Texas, and leading the industry since 1978, Atec Trans-Tool has built a hard-earned reputation among transmission rebuilders, automotive equipment warehouses, and professional shop technicians across the country. Their catalog spans an impressive range of specialty tools and shop equipment — all engineered with the demands of real-world transmission service in mind.

Unlike general-purpose toolmakers, Atec Trans-Tool focuses squarely on the powertrain service segment. Their product line covers automatic transmission tools, parts washers, shop tables and tanks, and a wide variety of related shop equipment. This singular focus means every tool is purpose-built: tolerances are tighter, materials are heavier-gauge, and designs are refined through decades of feedback from working technicians. It's no coincidence that transmission parts distributors, national tool truck dealers, and independent tool truck dealers all rely on Atec Trans-Tool as a go-to supplier.

Transmission Seal Tools Built for the Job

One of the most critical — and unforgiving — tasks in any transmission rebuild is seal service. Installing or removing a seal incorrectly can lead to leaks, comebacks, and costly rework. Atec Trans-Tool's lineup of Transmission Shaft Seal Tools is engineered to eliminate that guesswork. From lip seal protectors and lube tube seal replacers to shift lever seal remover/installer sets compatible with popular GM platforms like the 3L30, 4L60, and 4L60-E, these tools are designed to seat and extract seals cleanly without damaging delicate transmission bores or shafts.

Beyond seal tools, the Atec Trans-Tool catalog extends into clutch service tools, bushing drivers, air test plates, accumulator and servo piston removers, bearing cone pullers, and retaining ring pliers with extra-long handles for reaching deep into large transmission cases like the 6L50, 6L80, and 6L90. Each tool reflects the same philosophy: give the technician what they actually need to do the job right the first time.

Shop Equipment Built to Last

Atec Trans-Tool's reputation doesn't stop at hand tools. Their line of parts washers and shop tables — constructed from heavy-gauge steel — are engineered for the demands of a busy transmission shop. Parts cleaning systems feature powerful pump motors, adjustable timers, and high-capacity nozzle arrays, making the cleaning process as straightforward as loading a basket and pressing start. Shop tables and tanks are available in multiple configurations with optional casters, making them adaptable to a wide range of shop layouts.
