Welcome to the Sergeant Clutch app 👋
Family-owned on Walzem Road for over 22 years. Transmissions, engines, brakes, A/C and honest diagnostics — certified mechanics, quality parts, real warranties.
🚗 Step 1 — Your details + your first vehicle
REQUIRED TO USE THE APPTo get the app, every customer puts in their name, mobile number and email — and registers at least one vehicle: year, make, model and engine type, plus current mileage. You can add more vehicles later, any time. Your vehicle profile feeds straight into the diagnostic app later, so a sound check starts from your exact vehicle.
Demo copy on Rocky's phone: your details are saved only in this phone's browser storage — nothing is sent anywhere. In the live app (when Sergeant Clutch launches) this is what builds the shop's customer database.

Your vehicles, your reminders
Every vehicle you register is checked against the live NHTSA recall database, and the app tracks each one's oil-change countdown — no more windshield stickers. Every registered vehicle feeds the diagnostic app later, so a sound check starts from your exact make, model and engine.
➕ Add another vehicle
Does it sound like this?
Tap play and compare — these reference sounds are real recordings of actual vehicles. Your registered vehicle is already on file, so this check starts from your exact vehicle, not a generic one.
Four steps, then leave it to the pros
Tell us what's going on, record the actual noise, get a careful read on what it could be — then let the professionals confirm it. In the live app your answers and your recording travel with your booking, so the shop hears the noise before your car rolls in.
Hold the phone near the noise (safely — never while driving) and tap record. Your recording stays on this phone in this demo copy.
Compare with the real reference recordings below. Sounds can point to more than one cause, so the app only ever offers possibilities — never a diagnosis.
Reference sounds are real vehicle recordings from Freesound: “Large Old Car Starts and Stops with Brake Squeaks and Gears” by craigsmith (CC0); “Car_ReverseWhine_2” by jessepash (CC BY 3.0); “Interior Prius driving — suspension bumps” by buddhafish (CC0).
Whatever it is, the fix starts the same way: a proper check at the shop.
Book service or ask for a quote
In the live app this lands in the owner's email and as a text to his phone through the PremierTAP system — the thing his current website doesn't do.

Sales demo — built for Sergeant Clutch by NousSi.Tech (PremierTAP for Business). Reference sounds are real vehicle recordings from Freesound, credited in the That Sound? section. Recall results come live from NHTSA (api.nhtsa.gov); when a live check isn't possible, the app says so and shows clearly-labeled sample data instead.
