The crane
Engine swaps in the driveway.
The crane-equipped rig means an engine swap in your driveway is a normal Tuesday: the dead unit comes out, the replacement goes in, gets dressed and fired, with no shuttling your vehicle across town and no shop backlog. The same crane does the lifting on heavy equipment and large vehicles.
David runs the shop the way a good foreman runs a floor: show up when you said, do the job once, leave an itemized bill. Smaller jobs work the same way. A diagnostic visit is a full scan, live data and a written find, and brakes are pads, rotors and hardware done right where the car is parked.
Transmissions
Priced for your vehicle.
Give the quote builder the year, make and model, and it prices the transmission that's actually in your vehicle: its book hours for a remove-and-replace and, for an automatic rebuild, every part that goes in, by part number, at what it sells for today.
A rebuild is the whole job: out, torn down and rebuilt, with the valve body, torque converter, bushings, bearings, friction modules, pistons and the soft-parts kit, plus the updated part for anything your unit is known to fail. If your vehicle isn't on file yet, the quote says so and gives a typical range, and the exact unit is priced before any work starts. Old three-speed manuals get a full teardown, new synchros and bearings, set up on the bench.
