REBUILD TRANSMISSIONS Built to Last

Thorough diagnostic scanning, pressure testing, and fluid analysis guide every repair decision we make.

Diagnose and Repair Transmissions with Precision

Serving domestic and import platforms across Manor and the Austin metro

Lafayette Drive Train Specialist brings nearly 10 years of hands-on transmission experience to every vehicle that enters the shop in Manor, Texas. Evan Medrano specializes in domestic and import transmissions across 6-, 8-, 9-, and 10-speed platforms, addressing the demands that Austin metro driving conditions place on modern drivetrains. Family business carrying the lineage, this shop ensures no vehicle leaves without our seal of approval—a commitment rooted in thorough diagnostic work, not guesswork.


When your transmission begins slipping, hesitating, or showing warning lights, you're facing more than an inconvenience—you're risking further damage and costlier repairs down the road. The difference between a correct repair and an unnecessary one often comes down to diagnostic precision: scanning for fault codes, testing hydraulic pressure, and analyzing fluid condition before recommending any parts or labor.


Lafayette Drive Train Specialist operates on the principle that transparency and technical accountability go hand in hand. Every diagnostic report is written out and explained in plain terms, so you understand what's failing, why it matters, and what the repair will accomplish before any work begins.

Diagnostic Clarity Drives Every Repair Decision

Evan uses diagnostic scanning, pressure testing, and fluid analysis to pinpoint the exact source of transmission trouble before recommending parts or service.

Specialized in late-model transmissions, the shop handles the complex electronic and hydraulic systems found in newer domestic and import vehicles. This level of diagnostic rigor means you're not paying for parts that don't solve the problem, and you're not left wondering whether the repair was necessary.


Transparent diagnostic reports walk you through what was found, what needs attention, and what can wait. You'll know the condition of your transmission before any wrench turns, and you'll have a clear picture of the work ahead.

Whether you're dealing with automatic or manual transmission issues, the service approach remains the same:


  • Complete diagnostic scanning identifies electronic faults and system performance issues before disassembly
  • Pressure testing reveals internal hydraulic failures that external inspections can't detect
  • Fluid analysis uncovers contamination, overheating, and wear patterns that guide rebuild decisions
  • Stop-and-go traffic and summer heat in the Austin metro place unique strain on transmission cooling and shifting systems


Bring your vehicle in for a walk-in evaluation during business hours, or reach out for a free diagnostic consultation to discuss what you're experiencing.

Built on Accountability and Hands-On Craftsmanship

Lafayette Drive Train Specialist operates from a single-bay shop on the border of Travis and Williamson counties, where Evan personally oversees every transmission repair, rebuild, and diagnostic. Written warranty backs our work, giving you documentation and recourse if anything doesn't perform as promised. This isn't a high-volume operation—it's a family business that prioritizes doing the work right over doing it fast.

Every transmission that leaves the shop has been tested, approved, and signed off by the technician who built it. That level of personal accountability means you're not handed off to a service writer or left wondering who actually touched your vehicle—Evan stands behind the diagnosis, the parts selected, and the finished repair.



Stop by the shop in Manor Monday through Friday between 8am and 5pm, or Saturday from 9am to 12pm, and let's talk about what your transmission needs.
