How much does transmission fluid service cost in Denver, CO?

Transmission fluid service in Denver, CO typically costs $200–$380 for a drain and fill, or $125–$300 for a machine flush. They are different jobs: a drain and fill replaces 30–50% of the fluid, while a machine flush exchanges 80–100%. A quote for one is not a quote for the other, and a pan drop with filter replacement costs extra.

Likely causes

• Aged fluid — Fluid degrades with heat and mileage; neglected fluid causes slipping that feels like failure.
• Worn internals — A flush won't fix worn internals, and a drain won't fix a leak.

What you can check yourself

• Ask which service the quote names — drain and fill, or machine flush — and what fluid it uses.
• Specialty fluids (CVT, dual-clutch, some 8-speeds) cost more; confirm yours.
• If the transmission slips, get a diagnosis first — fluid service is maintenance, not a rebuild.

Typical cost

Typical in Denver, CO: drain and fill $200–$380; machine flush $125–$300.
