Two numbers decide most Ford repair estimates. One is the shop's hourly labor rate. The other is the labor time published for that job in a flat-rate guide. Parts go on top of both. Any quote worth comparing will separate those lines, since two shops quoting $4,500 for a transmission can be selling very different work.
Expect $120-$159 per hour from an independent shop anywhere in the country this year. California prices are at the top of that spread, which puts Los Angeles and Orange County independents at $155-$200 per hour. Dealers add another $20-$40 over whichever independent shop is nearest. Diesel service and ADAS calibration push higher still.
Flat-rate billing decides the hours. Your shop charges the time listed in a labor guide such as Mitchell or AllData, rather than the hours a technician spends under the truck. Geography explains the rate you're quoted. The hours behind it are supposed to match everywhere for identical work, so a quoted time well above the guide deserves a question.
A slipping transmission doesn't always mean the unit has to come apart. Shops price this work in tiers, so ask which tier your truck belongs in before anything else.
The four-speeds used through 2008 are the least reliable of any Ford automatic. Cost climbs as gear count climbs. That puts the 10-speed at the top, since its internal layout is more complex and fewer shops keep the tooling for one.
The expensive version of this repair is the one an owner postponed. Most owners describe the same symptom first, a shudder somewhere around 40-60 mph under light acceleration. That points to a torque converter clutch beginning to slip. Drive another six months on that, and metal debris works its way into the valve body. Your $1,200 repair is now a $4,000 one. Have a dealer check your VIN against open programs before authorizing any of it. Trucks from 2017 forward may still carry powertrain coverage under five years or 60,000 miles.
Where the replacement unit comes from will set most of the price.
Labor decides the rest. A straightforward V8 swap takes 8-15 hours. An EcoBoost F-150 or a Super Duty diesel will need 15-25, given everything that comes off first. Twenty hours at $160 puts $3,200 in labor on the estimate before anyone touches a part.
Three ranges cover almost every F-150 that comes through here.
Plan on another $400-$900 for wear parts while the engine is out of the truck. The bay is already open at that point. A timing set, a water pump, a thermostat, hoses, motor mounts, and spark plugs cost almost nothing in labor. Skip them, and you'll pay for the same labor a second time inside a year or two.
A used engine costs the least and carries the shortest warranty. Ours come with three months, electrical excluded. Time out of service separates the two remaining options sharply. Your vehicle stays off the road for 7-14 days waiting on a rebuild, since the machine work happens on your own block. A reman unit comes off a production line already assembled and reaches the shop in 2-5 days, though you'll pay roughly $1,500 more for it on a mainstream V6 or V8. Rare engines and heavy-duty diesels still justify a rebuild. So does any collector vehicle where the original block carries value nobody wants to throw away.
The 6.7 Power Stroke has carried a Bosch CP4.2 high-pressure fuel pump since 2011. An internal failure sends metal debris through the rails, the lines, and every injector. One pump then becomes a full fuel system replacement at $8,000-$15,000. Dealer quotes on that job pass $12,000 often enough that owners should plan for it. Trucks built 2011-2016 have the original design and the highest exposure.
Earlier diesels have their own expensive list. On 6.0 Power Stroke trucks built 2003-2007, head gaskets, EGR coolers, and oil coolers account for most major repairs. The 6.4 engines from 2008-2010 add turbo and radiator work on top of that. Any of those totals will exceed the market value of a high-mileage truck, which is exactly where a used engine changes the decision.
The difference between a 10-hour job and a 25-hour job is almost always access to the part.
Ask which of those apply to your truck before you compare quotes. Eighteen hours on a 4x4 diesel is reasonable. The same eighteen on a two-wheel-drive 5.0 earns a second opinion.
Two estimates for one repair rarely share the same assumptions. Line them up before choosing.
Ask the low bidder what the high bidder included in the price. Most differences resolve right there, without a third estimate.
Shops in California must give you a written estimate before they begin any repair. They can't exceed it without your authorization. Ask for five lines in writing.
The Bureau of Automotive Repair licenses every repair shop in the state and publishes consumer rules on its auto repair page. License status for any shop is searchable there.
Repair shops rarely finance jobs themselves. Owners generally choose among four options.
Almost nobody totals the interest across the full term before signing. Our guide to paying for car repairs covers those tradeoffs, alongside a longer breakdown of options when a repair exceeds available cash.
Parts remain the one line an owner controls. A salvage engine or transmission cuts the parts side by 50-70% against a remanufactured unit. Labor hours stay identical either way.
Most shops will install a customer-supplied engine or transmission. Two questions decide it. Will the shop warranty its own labor on a part it didn't sell? Who pays for that labor if the part fails within the warranty period? Get both answers in writing before the vehicle goes on a lift.
