Your Kia Deserves More Than Just Another Repair Shop
You felt it on the way to work this morning. A hesitation between gears. A shudder pulling out of the driveway. Maybe the transmission warning light blinked on, then off, then on again. And now the quiet worry starts humming in the back of your mind: is this the beginning of a repair that swallows an entire paycheck? Your Kia Optima, Sorento, Sportage, or Telluride has carried your family reliably, and the idea of losing it to one big drivetrain failure is exactly the kind of stress you don’t need.
At Glenwood Foreign Car, 333 Woolston Drive in Yardley, PA, we have been diagnosing and repairing transmissions since 1977. Our ASE Certified Techs treat a slipping or hesitating Kia the way we would treat our own vehicle — with a real diagnosis first, not a guess and an oversized invoice. You get a straight answer about what your transmission actually needs.

Most catastrophic transmission failures start as small, ignorable problems. Regular maintenance keeps your Kia shifting smoothly and prevents the $3,000 surprise down the road.

If a rebuild or swap becomes the smart move, our transmission replacement service gets you back on the road with confidence.
Model-Specific Kia Transmission Expertise
Kia Optima Service and Repair
The Optima has long been Kia’s popular midsize sedan, and its automatic transmissions respond well to consistent fluid service. We diagnose slipping and delayed engagement early, before a minor solenoid issue becomes a full replacement, keeping your daily commute smooth and predictable.
Kia Sorento Service and Repair
As a family SUV that hauls people and gear, the Sorento’s transmission works hard, especially with towing or heavy loads. We address shudder, harsh shifts, and torque converter concerns, and we keep the drivetrain fluid clean so those extra miles do not shorten its life.
Kia Sportage Service and Repair
The Sportage is a compact crossover built for stop-and-go suburban driving, which is exactly the duty cycle that stresses a transmission. We watch for delayed engagement and rough downshifts, servicing fluid on schedule to keep this dependable commuter dependable.
Kia Telluride Service and Repair
The Telluride’s eight-speed automatic is a strong unit, but a three-row SUV that carries a full family benefits from meticulous fluid maintenance. We service it to factory specification and diagnose any shift complaints thoroughly, protecting one of Kia’s most valued vehicles.
Kia Soul Service and Repair
The Soul’s IVT and conventional automatics have their own service quirks that a generalist shop can overlook. We use the correct fluid and diagnostic approach for each, addressing hesitation and noise so this efficient little hatchback keeps running the way you expect.
Kia Forte Service and Repair
A dependable compact commuter, the Forte relies on either an IVT or a conventional automatic depending on the year. We diagnose CVT-style droning, harsh engagement, and fluid contamination, keeping the total cost of ownership low the way Forte drivers expect.
Common Transmission Issues Across Kia Models
Across the Kia lineup, a handful of transmission concerns show up repeatedly. Here is what we see most often and how we address it.
- Delayed or harsh engagement: A pause or clunk when shifting into drive or reverse often points to fluid condition or valve body wear, which we diagnose before recommending anything drastic.
- Transmission slipping: When RPMs rise without matching acceleration, we check fluid level, condition, and internal clutch health to pinpoint the true cause.
- Shudder during acceleration: A torque converter shudder frequently traces back to old or incorrect fluid, and a proper service often resolves it without a rebuild.
- Dual-clutch jerkiness: DCT-equipped Kias can feel abrupt at low speeds; we perform adaptation and inspect the clutch pack rather than assuming failure.
- Warning lights and stored codes: A transmission or check-engine light gets a full scan so we treat the actual fault, not just the symptom.
- Fluid leaks: Seals and cooler lines fail over time; we locate and repair the leak before low fluid causes real internal damage.
