What are the warning signs of a failing transmission?
AAA lists these signs. Transmission trouble rarely fixes itself and tends to get worse, so describe exactly when it happens: first thing in the morning, after the engine warms up, or only at highway speed. That helps a mechanic diagnose it faster.
- Jerking, hesitating or trouble shifting into drive, reverse or between gears while driving.
- Slipping, when the engine revs but the car doesn't accelerate as it should. In some CVTs and hybrids, revving without immediate acceleration is normal behavior, AAA notes, so a pattern or decline in performance is the thing to watch.
- Whining, humming or grinding when driving, reversing or sitting in neutral.
- Fluid under the car. Transmission fluid is usually red or pink but can be green, yellow, purple or blue, and it's supposed to stay sealed inside. Consumer Reports adds that, unlike engine oil, it should never burn off, so a low level points to a leak.
How much does transmission repair cost?
RepairPal's national estimates, which don't include taxes or fees and don't account for your location, put an average transmission replacement at $6,238 to $6,764, with labor of $1,127 to $1,654 and parts around $5,110. A fluid change averages $294 to $356. These are national averages, not Sacramento quotes.
RepairPal also notes that a replacement can often cost less than a repair, especially on older vehicles, and that newer vehicles typically get a replacement whenever a rebuild would be needed, because manufacturers increasingly replace the unit and have the old one remanufactured by a third party. Ask any shop to quote both repair and replacement, and to explain why it recommends one.
- Ask what kind of problem it is. A leak, a sensor or valve problem and internal wear lead to different estimates, so ask the shop to explain which one you have and how it knows.
- Vehicle matters. RepairPal's fluid-change ranges include $187 to $215 for a Honda Civic, $254 to $328 for a Toyota Camry and $548 to $640 for a Ford F-150.
How often should transmission fluid be changed?
Check your owner's manual first. Consumer Reports says intervals vary widely, from as little as 30,000 miles to more than 100,000, and that some newer transmissions have fluid meant to last the life of the car. Most CVTs still need inspections or fluid changes, and they need CVT-specific fluid. AAA says many cars call for a change somewhere between 30,000 and 60,000 miles.
Towing, carrying heavy loads, long idling, and dusty or extreme conditions are the kind of use that makes manufacturers recommend a "severe" schedule. Sacramento's summers are one reason to ask about it: NOAA's 1991-2020 normals show about 76 days a year at 90°F or above. Consumer Reports also warns that power-flushing a high-mileage transmission can dislodge sludge and cause clogs, so ask what method a shop plans to use and where the automaker recommends it.
What is the difference between rebuilt, remanufactured and used?
These terms matter for price and warranty. In California, an estimate must treat each part as new unless it is specifically identified as used, rebuilt or reconditioned, and the invoice must say so. BAR's consumer guide says rebuilt parts often involve a core charge, a payment for the old part going back to the supplier.
The source of a replacement unit can also affect manufacturer coverage. Subaru's CVT warranty extension, for example, applies only to the original CVT or genuine replacements, including units remanufactured by Subaru, and not to salvage-yard units or CVTs rebuilt by others. Ask the shop:
- Is the unit new, remanufactured, rebuilt or used, and who built it?
- Does the warranty cover parts and labor, and for how many months and miles?
- Will the shop replace related parts, such as the cooler or lines, and are they on the estimate?
- Who handles a warranty claim if the problem returns?
What is a teardown estimate?
If a shop has to take the transmission apart to find the problem, California's rules for a teardown estimate apply. BAR's consumer guide says the estimate must warn that the vehicle may not be able to be reassembled, state the cost including reassembly and replacing gaskets and seals, and say how long reassembly will take. After the teardown, the shop must write a revised estimate listing the parts and labor needed for the repair.
BAR also mediates complaints about engine and transmission rebuilding or replacement, so keep every estimate, authorization and invoice.
Do I need a specialty transmission shop?
Not always. Consumer Reports says a good mechanic will tell you when a job is outside what the shop handles and should go to a specialized facility such as a dealer or a transmission shop. Ask whether the shop works on your type of transmission, whether it's a conventional automatic, a CVT, a dual-clutch or a manual, and on your make.
Whatever the shop, it must be registered with BAR. Look it up in the DCA license search. If the repair might be covered by your manufacturer's warranty, a recall or a service contract, check that first, because the manufacturer can require warranty work to be done at its own facilities.
