Transmission Repair — Ladson, SC
From a routine fluid change to a full rebuild — honest diagnosis, written estimates, and a 12K-mile warranty on every transmission repair for automatic, CVT, and manual vehicles.
Transmission Slipping, Grinding, or Leaking Badly? Don't Drive It.
A transmission that is actively slipping, making loud grinding noises, or has lost most of its fluid should not be driven — every mile risks turning a repairable problem into a complete rebuild or replacement. Call us at 843-494-9179 and we'll help you determine whether it's safe to bring it in or whether a tow is the smarter call.
Transmission trouble is one of the most anxiety-inducing car problems — the repair bill potential is real, and the fear of being oversold is legitimate. At Ladson Auto Repair Shop, we start every transmission concern the same way: a thorough diagnostic scan and fluid inspection before recommending anything. The goal is to find the least invasive, most cost-effective solution — a $150 fluid service if that's what's needed, a solenoid replacement if that's the cause, and an honest recommendation for a rebuild or replacement only when the internal damage makes it necessary.
We service automatic, CVT, and manual transmissions for all makes and models, and we use the manufacturer-specified fluid for your exact vehicle — never a generic substitute. Every repair is backed by a 12,000-mile / 12-month warranty on parts and labor.
Most transmission failures don't happen suddenly — they give you weeks or months of warning. Catching the symptom early is almost always the difference between a $200 repair and a $3,000 rebuild.

Each transmission type has different fluid requirements, failure patterns, and service intervals. Using the wrong fluid — or the wrong service approach — for your specific transmission type can cause immediate damage. We identify your transmission type and service it correctly.
Uses a torque converter and hydraulically-controlled gear sets. The most common type in American, Japanese, and Korean vehicles. Fluid type varies by manufacturer (Dexron, Mercon, ATF+4, SP, etc.) — mixing fluid types causes seal damage.
Uses a steel belt and variable-diameter pulleys for smooth, gearless acceleration. Common in Nissan, Honda, Subaru, Toyota, and Mitsubishi. CVT fluid is not interchangeable with standard ATF — using the wrong fluid destroys the belt within miles.
Driver-controlled gear selection via clutch and shift linkage. Uses gear oil rather than ATF. Clutch wear is the most common maintenance item — clutch slipping, hard shifting, and noise are all diagnosable before complete failure.
Every level of transmission care under one roof — diagnosed correctly before anything is recommended.
The foundational maintenance service. We drain fluid from the pan — typically 40–60% of total volume — inspect the pan for metal debris (a critical indicator of internal wear), replace the filter, and refill with the OEM-specified fluid for your exact vehicle.
A machine-assisted service that replaces 90–95% of fluid — including fluid in the torque converter and cooler lines that a drain-and-fill cannot reach. Recommended when fluid is dark, degraded, or the vehicle has a long service gap with no flush history.
Shift solenoids control hydraulic fluid flow to engage each gear. When a solenoid fails, the transmission gets stuck in a gear, slips, or shifts harshly. Solenoid replacement is one of the most common — and most cost-effective — transmission repairs.
Transmission fluid leaks reduce hydraulic pressure — small leaks become catastrophic failures if ignored. We locate the exact leak source before recommending any parts, since leak location determines the repair complexity significantly.
The Transmission Control Module stores fault codes specific to transmission operation — gear ratio errors, solenoid circuit faults, speed sensor failures, and over-temperature events. These codes require a professional scanner with TCM access to read correctly.
When internal clutch packs, bands, bearings, or the torque converter are worn beyond fluid service or external repair, a rebuild disassembles the unit and replaces every worn component. Best for vehicles in otherwise good condition with significant value remaining.
When internal damage is too extensive for a cost-effective rebuild, or when rebuild labor cost approaches replacement cost, a remanufactured unit offers a fully restored transmission with a factory warranty. We evaluate both options transparently before recommending either.
Manual transmission clutch wear is gradual — slipping under acceleration, high engagement point, and difficulty getting into gear are all early warning signs. A worn clutch caught before complete failure avoids flywheel damage that significantly increases total repair cost.
One of the most common questions we hear is "how much does transmission repair cost?" The honest answer: it depends entirely on what's wrong. Here are realistic ranges for each level of service at our Ladson shop — we give you a written estimate before any work begins, so there are no surprises.
| Service | What It Addresses | Typical Range | When You Need It |
|---|---|---|---|
| Fluid Change (Drain & Fill) | Replaces 40–60% of fluid; replaces filter and pan gasket | $120 – $200 | Preventive maintenance every 30K–60K miles |
| Transmission Flush | Replaces 90–95% of fluid including torque converter and cooler lines | $150 – $250 | Degraded or dark fluid; high mileage with no flush history |
| Solenoid Replacement | Repairs shift, pressure, or TCC solenoid faults | $150 – $500 | Harsh shifting, stuck gears, or solenoid fault codes |
| Seal & Gasket Repair | Stops external fluid leaks at pan, output shaft, or case | $150 – $600 | Red fluid dripping or pooling under vehicle |
| Speed Sensor Replacement | Repairs input/output speed sensor circuit faults | $150 – $350 | P0715, P0720 codes; erratic speedometer or shift timing |
| Clutch Replacement (Manual) | Clutch disc, pressure plate, release bearing, flywheel inspection | $700 – $1,500 | Clutch slipping, hard engagement, or burning smell |
| Transmission Rebuild | Full internal rebuild — clutch packs, bands, seals, bearings | $1,500 – $3,500 | Internal slipping, major fluid burn, bearing failure |
| Transmission Replacement | Remanufactured unit with new torque converter | $2,500 – $5,000 | Total internal failure; when rebuild cost exceeds replacement value |
Charleston metro summers push ambient temperatures above 95°F regularly — and inside a transmission fluid running in stop-and-go traffic on Dorchester Road or I-26, temperatures can exceed 200°F. Every 20°F rise in operating temperature above the design threshold cuts transmission fluid life roughly in half.
If you tow a boat, camper, or trailer — common in the Lowcountry — transmission temperatures climb even faster. Towing with degraded fluid is one of the fastest ways to turn a $150 fluid service into a $3,000 rebuild. We check fluid condition and inspect the transmission cooler as part of every service.
Transmission diagnosis done right takes more than a code scan. Here's our process from your first call to the final repair:
We start by asking the right questions: When does the slipping happen — cold, warm, or both? Under acceleration, or during light throttle? Only in specific gears? When did the fluid last get changed? For a transmission, operating temperature and service history matter enormously — a fluid change that's 80,000 miles overdue in South Carolina's heat looks very different from a vehicle with current maintenance records showing the same symptom. We also check for any recent repairs that could be related — a recently replaced speed sensor, a battery replacement that reset adaptive shift tables, or a prior transmission service at another shop.
Transmission fluid is one of the most informative diagnostic indicators available. Bright red fluid = healthy. Pink fluid = water contamination. Dark brown = heat-degraded. Black = severely burned, likely internal damage. We also check fluid smell — a burnt odor indicates overheated clutch material has contaminated the fluid. On accessible transmissions, we inspect the pan for metallic debris: fine metallic particles are normal wear, but flakes or chunks indicate broken internal components and change the repair recommendation significantly.
We scan the Transmission Control Module for all stored and pending fault codes — gear ratio errors, solenoid circuit faults, speed sensor faults, over-temperature events, and pressure control codes. Then we go deeper with live data: monitoring actual gear ratios versus commanded ratios, solenoid duty cycles, fluid temperature, torque converter lock-up behavior, and adaptive shift tables. A solenoid that codes intermittently may look fine in resistance testing but show erratic duty cycle behavior in live data — which is the real diagnosis.
Many transmission symptoms only appear at specific temperatures, speeds, or throttle positions. We road-test with the scan tool connected and recording live data — monitoring every shift event, torque converter engagement, and fluid temperature in real conditions. This is especially important for intermittent concerns that may not reproduce on a lift but appear consistently after the transmission reaches normal operating temperature, or only under highway load.
Once we know the cause and severity, you receive a written estimate with every option explained: what the repair is, what it costs, and what happens if it's deferred. We give you a tiered view — immediate safety concerns, recommended repairs, and what can wait. For major repairs like rebuilds or replacement, we give you an honest assessment of the vehicle's overall condition and value so you can make an informed decision. No pressure, no upselling — just the facts and the prices.
Every manufacturer uses different fluid specifications, solenoid designs, and TCM logic. We service transmission systems correctly for every brand — using OEM-specified fluid, not a generic "multi-vehicle" substitute that can cause compatibility issues.

The key ones to act on immediately: slipping where the engine revs but the car doesn't accelerate, loud grinding or clunking noises, a major fluid leak, or a transmission warning light. Early warning signs you can address without stopping driving: rough or harsh shifting, occasional shudder (especially in CVTs), a burning smell, or delayed engagement when selecting Drive or Reverse. Catching any of these early is almost always the difference between a $200–$500 repair and a $3,000 rebuild.
A fluid change (drain and fill) drains the fluid from the pan — about 40–60% of total volume — replacing the filter and refilling with fresh fluid. A flush uses a machine to cycle new fluid through the entire system including the torque converter and cooler lines, replacing 90–95% of the old fluid. A flush is more thorough but more expensive and should never be performed on a transmission that is already slipping — it can dislodge debris that was acting as a temporary seal and accelerate failure. For a healthy transmission receiving routine maintenance, a drain-and-fill is usually sufficient.
See the full cost table above for realistic ranges. In short: a fluid change runs $120–$200; a solenoid replacement $150–$500; a seal repair $150–$600; a rebuild $1,500–$3,500; and a remanufactured replacement $2,500–$5,000. We provide a written estimate before any work begins — you'll know the exact cost for your specific vehicle before we touch anything. Call 843-494-9179 to describe your symptoms and get a rough estimate over the phone.
Most automatic transmissions benefit from a fluid service every 30,000–60,000 miles. CVTs are particularly sensitive and typically need fluid every 30,000–60,000 miles — degraded CVT fluid is the most common cause of CVT shudder and early failure. In South Carolina's heat, especially if you tow or spend time in stop-and-go traffic, check fluid condition every 30,000 miles. Many modern vehicles are advertised as "lifetime fill" — we still recommend inspecting the fluid condition at 60,000–100,000 miles regardless.
No. A slipping transmission means clutch packs are engaging and disengaging incorrectly under load — generating friction and heat that rapidly wears out every internal component. What might be a $300–$500 solenoid or fluid repair caught early can become a $3,000 rebuild within a few hundred miles of continued slipping. Call us at 843-494-9179 for guidance on whether to drive in carefully or arrange a tow.
A CVT (Continuously Variable Transmission) uses a steel push-belt and variable-width pulleys instead of traditional gear sets, providing smooth gearless acceleration. Common in Nissan, Honda, Subaru, and Toyota. CVT fluid is chemically different from standard ATF — using the wrong fluid type causes immediate damage to the belt and pulley surfaces. CVTs also experience a characteristic shudder at low speeds when fluid is degraded; a proper CVT fluid change resolves this in most cases without any mechanical repair needed.
It depends on the vehicle's overall condition and remaining value relative to the repair cost. A rebuild ($1,500–$3,500) disassembles and restores the existing unit — often the best value for vehicles worth $8,000+ in good condition. A remanufactured replacement ($2,500–$5,000) swaps in a factory-rebuilt unit. For vehicles with high mileage and multiple other issues, the total repair cost may exceed the vehicle's value. We provide an honest assessment of both options and the vehicle's overall condition before recommending either — and we never push the more expensive option if the less expensive one solves the problem.
Yes — all three. We service automatic transmissions for all makes including Ford, GM, Toyota, Honda, Hyundai, BMW, and Mercedes; CVTs for Nissan, Honda, Subaru, Toyota, and others using the correct CVT-specific fluid; and manual transmissions including clutch replacement, flywheel service, gear oil changes, and synchro diagnosis. Each transmission type gets the correct OEM-specified fluid and service procedure for that specific application.
