Why ProAuto
What sets a tested unit apart from a pulled-and-shipped one.
Compression-tested, not guessed
Every engine goes through a full compression and leak-down test before we quote it. Results are logged against the donor VIN and sent with your quote - so you know what you're getting before you pay.
Documented mileage
We record the odometer reading from the donor vehicle and log it against the VIN. You get an actual number, not "low miles" with no backup.
Warranty on every unit
Every engine and transmission ships with a 1-12 month parts warranty from delivery, covering internal mechanical failure under normal use. Grade determines the term.
Freight included in every quote
Shipping cost is part of your quote from the start. No surprise freight charges, no separate invoices - the number we give you is the number you pay.
How it works
From request to delivery, with fitment confirmed before you pay.

What Customers Say
100+ reviews from shops and drivers.
Ordered a full engine on Monday, had it installed by Thursday. Compression numbers matched what they sent us exactly.
Quoted a used transmission for a 2017 Silverado on a Tuesday. Had it in our bay by Friday. Shifts clean - no issues three months later.
They sent the actual mileage documentation with the VIN. That level of transparency is rare - most places just say "low miles." Engine ran perfectly from day one.
