How I Saved $4000 Rebuilding My Own Transmission In My DRIVEWAY.

As someone who works at a hospital—not a repair shop—I decided to tackle a full rebuild of my 6L80 transmission right in my driveway. I’m here to show that, with determination and the right parts, anyone can achieve a complete rebuild without needing years of mechanic experience.

In this video, I walk you through every step as I replace each component, including the Transtar Master Rebuild Kit, a Recon Billet JMBX Torque Converter, a new GM pump, rotor, and vanes, and more. This is a thorough overhaul, and I’ve listed every part below to help you plan your own project:

Parts Installed:

Transtar Master Rebuild Kit
Recon Billet JMBX Torque Converter (from Transtar)
New pump, rotor, and vanes (GM)
New bellhousing (GM)
All new Exedy clutches
All new bushings
Sonnax Dam Lube Cover
Sonnax Zip Kit
Sonnax Line Pressure Boost Kit

Using HP Tuners for tuning, I set it up with no TCC applied gears 1-4, and zero slip, enhancing durability for the long haul.

Whether you’re a DIY enthusiast or just looking to save money, give your transmission a second life and prove you can do it right at home. Save $4000 by tackling the job yourself!
