2018 Chevrolet Silverado 1500 torque converter replacement: parts and labor
Labor runs $660 to $1,275 (the job takes 6 to 9 hours at typical independent-shop rates), and the torque converter itself typically costs $180 to $675 for the 2018 Chevrolet Silverado 1500, plus $120 to $220 in atf (11 to 13 qts) + filter kit. Prices updated September 2026.
| Engine | Parts | Labor | Estimated total |
|---|---|---|---|
| 4.3L V6 | $180 to $450 | $660 to $1,200 (6.0 to 8.0 hrs) | $960 to $1,870 |
| 5.3L V8 | $200 to $475 | $660 to $1,200 (6.0 to 8.0 hrs) | $980 to $1,895 |
| 6.2L V8 | $250 to $675 | $715 to $1,275 (6.5 to 8.5 hrs) | $1,085 to $2,170 |
Coverage note: 5.3L eAssist mild hybrid (rare fleet only HP2 package, roughly 500 built for 2018): uses a unique 8 speed hybrid torque converter (GM 24297075, $673) and hybrid specific labor, so it is excluded from the 5.3L row. No SS or performance trim existed for the 2018 Silverado 1500, so nothing else is excluded.
RepairPal and YourMechanic style estimators quote generic torque converter replacement around $1,500 to $2,500 but do not distinguish 6L80 from 8L90 trucks, which matters here because the GM 8L90 converter (24297076) lists at $611 versus $314 to $370 for 6L80 units. Dealer pricing carries a real premium on this truck: a documented out of warranty dealer quote was $2,996 and 2026 dealer totals run $2,800 to $3,600, driven by list price GM parts, $190 to $250 per hour labor, and the mandatory Mobil 1 LV ATF HP fluid fill. An independent transmission shop with a quality reman converter typically lands $1,000 to $2,200 for the same job.

The torque converter is the fluid coupling between the engine and the automatic transmission in your 2018 Chevrolet Silverado 1500. It lets the engine keep spinning at a stoplight, multiplies torque when you pull away, and at cruising speed an internal lockup clutch grips solid to stop wasting fuel. That clutch is the part that wears out, and because the converter bolts on between the engine and transmission, replacing it means removing the transmission, which is why labor is most of the bill.
Four signs it’s the torque converter
Shudder at steady speed
A rumble-strip vibration at light throttle on the highway. The classic sign of a worn converter lockup clutch.
RPM flares, truck doesn't
Engine revs climb without matching speed. The converter or transmission is slipping instead of gripping.
Delayed or harsh engagement
A pause or clunk when shifting into drive or reverse, especially cold.
Hot, dark, or burnt fluid
A slipping converter cooks the fluid. Dark color or a burnt smell means friction material is circulating.
The free check: on a quiet road, hold a steady 45 to 55 mph at light throttle. A vibration that appears in that zone and fades when you accelerate or lift off points at the converter clutch. Mention exactly when it happens to your shop; it is the single most useful thing you can tell them.
What a torque converter replacement is like on the 2018 Chevrolet Silverado 1500
The 2018 Silverado 1500 splits by transmission, not just engine: the 4.3L LV3 V6 and most 5.3L L83 trucks run the 6L80 six speed, while every 6.2L L86 gets the 8L90 eight speed, and 5.3L trucks on LTZ and High Country with the NHT Max Trailering package also got the 8L90. Check the RPO sticker in the glovebox: MYC means 6L80, M5U means 8L90. If your 5.3 is an eight speed, use the 6.2L row for parts pricing because the converter is the pricier 8L90 unit, though labor is the same pull.
The 8L90 is the transmission behind the famous TCC shudder saga (TSB 18-NA-355 and 19-NA-044, plus the Won v. GM class action). GM's prescribed first step is a flush with Mobil 1 Synthetic LV ATF HP, the blue label fluid sold as GM 19417577, and a large share of shudder complaints resolve with that roughly $400 to $500 service alone. Do not let a shop sell a converter on an 8L90 truck until that flush has been tried, unless debris or a failed stall test proves the converter is mechanically done. When the converter does get replaced, GM superseded the original 24297076 through updated designs, so a 2026 replacement is a later revision than what failed.
Parts pricing is unusually well documented for this truck. RockAuto lists remanufactured 8 speed converters at $208 to $257 with a $225 core charge, GM Genuine 6L80 units at $314 to $370, the LuK TC0017 for the 6L80 at $443 with no core, and the GM Genuine 8L90 converter 24297076 at $611. O'Reilly's 2018 Silverado listing runs $250 to $543 with a $397 average. Billet upgrade converters from Tier One or Circle D run $600 to $900 and are popular on 8L90 trucks precisely because the stock design is the failure point, but they push past this estimate's aftermarket range.
Labor is a full transmission R and R either way: driveshaft out, exhaust hardware and crossmember loose, cooler lines off, and on 4WD trucks the transfer case adds roughly an hour, which is most of the spread in the labor column. Real world anchors: a 2016 5.3 8L90 owner on Silverado Sierra forum was quoted $2,996 at a dealer out of warranty for this exact job, a reputable independent transmission shop quoted about $2,000 for a billet converter with valve body work, and 2026 dealer totals for the 8L90 converter run $2,800 to $3,600, which frames the independent shop range here as the sane middle.
Do not confuse converter shudder with the separate Chevy Shake complaints on 2014 to 2018 trucks: TCC shudder shows up as a rumble strip feel at 25 to 45 mph under light throttle at lock up, while the shake tied to driveshafts and wheels appears at highway speed regardless of gear. Also budget honestly for fluid: a converter swap on the 8L90 means 11 to 13 quarts of the $13 to $16 per quart Mobil 1 LV ATF HP, while 6L80 trucks take cheaper Dexron VI, which is why the consumables high end belongs to the eight speed trucks.
Estimate note: these are researched independent-shop ranges, not a guaranteed quote. The only exact number is one from a shop that has seen your car.
Frequently asked questions
How much does a 2018 Chevrolet Silverado 1500 torque converter replacement cost?
A 2018 Chevrolet Silverado 1500 torque converter replacement typically runs $960 to $2,170 at an independent shop, parts and labor included. The torque converter itself is $180 to $675, labor makes up most of the rest, and the job takes 6 to 9 hours.Why does the price change with the engine?
The 2018 Chevrolet Silverado 1500 came with more than one engine, and they do not share the same part or the same access. A tighter engine bay or extra teardown adds labor hours, and the part price moves too. Sites that show one national number flatten that out. Pick your engine on the estimate above for a closer figure.What are the signs of a bad torque converter?
The classic sign is a shudder at steady highway speed under light throttle, a rumble-strip vibration that comes and goes as the converter's lockup clutch grabs and slips. Others: engine RPM flaring up without the truck speeding up, a delayed or harsh clunk into drive, a whine that changes with gear, and transmission temperature climbing on grades. These symptoms overlap with internal transmission problems and even engine misfires, so get a real diagnosis before paying for either.Can I drive my Chevrolet with a bad torque converter?
Briefly, but it gets more expensive the longer you wait. A slipping converter sheds clutch material into the transmission fluid and runs hot, and that debris circulates through the entire transmission. Caught early, this can be a converter and fluid job. Ignored, it becomes a full rebuild at several times the price. If it shudders occasionally, book the repair soon; if it slips hard or overheats, stop driving it.Should the transmission be rebuilt at the same time?
Fluid condition is the tell. If the fluid is clean and the failure is isolated to the converter clutch, a converter-only replacement is a legitimate fix, and the labor is already paid since the transmission comes out either way. If the fluid is dark, smells burnt, or carries metal or friction material, converter debris has been through the whole unit and a reputable shop will recommend a rebuild instead of bolting a new converter to a dying transmission. Ask to see the fluid and the pan.How long does a torque converter last?
Usually the life of the transmission, commonly 100,000 to 200,000 miles. The weak point is the lockup clutch inside the converter, which wears like any friction clutch, and worn-out fluid accelerates it. Regular transmission fluid service is the cheapest way to extend converter life, and it is also what keeps a future repair converter-only instead of a rebuild.Are there recalls on the 2018 Chevrolet Silverado 1500?
Yes, NHTSA lists 7 recalls for the 2018 Chevrolet Silverado 1500. Recall repairs are done free of charge at a franchised dealer for that brand, so it is worth checking your VIN before paying a shop for related work.
