Our transmission service includes fluid inspection and replacement, filter changes, diagnostics, and full rebuilds or replacements if needed. Whether you’re dealing with slipping gears or delayed shifting, we’ll restore smooth performance. 

Common signs include uneven tire wear, bouncing after bumps, steering instability, or a rough ride. We inspect shocks, struts, springs, and bushings—then repair or upgrade your suspension for better handling and durability. 

We inspect pads, rotors, calipers, brake fluid, and lines for wear or leaks. Whether you need a basic pad replacement or a full brake system overhaul, we ensure your truck stops safely and reliably every time. 

Warning lights, poor fuel economy, rough idling, or lack of power are all signs your engine needs a checkup. We use advanced scan tools and hands-on testing to pinpoint issues—no guesswork involved.
