# When does my 2022 4Runner need transmission fluid service?

Your **2022 Toyota 4Runner** needs transmission fluid service every **30,000 to 60,000 miles** for normal driving. Toyota calls its WS fluid "lifetime" up to **100,000 miles**, but 4Runner owners drain and refill **3-3.5 quarts** every **30,000 miles** to mix fresh fluid and extend life. This keeps average fluid age under 100,000 miles.

## Key Service Intervals
Here's what 4Runner owners and guides say:

| Driving Type | Recommended Interval | Method | Notes |
|---|---|---|---|
| Normal | Every 30,000 miles | Partial drain (3.5 quarts) | Keeps old-new mix fresh. Popular on forums. |
| Normal (Toyota) | 100,000 miles | Inspect/replace if needed | Official, but owners do sooner. |
| Severe (towing, off-road) | Every 60,000 miles | Drain and refill | For hot climates or heavy use like near King of Prussia, PA. |

Partial drains beat full flushes. They leave some clutch material in the fluid to protect gears. Full flushes can shock the transmission. One owner did partials every **30k-50k miles** with zero issues.

"Change 3.5 quarts every 30,000 miles to maintain old-new mixture average fluid life under 100,000 miles," says DougR, 4Runner forum expert with detailed spreadsheets (Source: Toyota-4Runner.org, 2018 analysis).

## Step-by-Step DIY Guide
Do it yourself to save $200-400 at a shop. You need:
- **Toyota WS ATF** (3.5-4 quarts)
- Drain pan, wrench, pump
- OBD scanner for temp (aim for 104-113°F)

1. Warm engine to operating temp.
2. Drain ~3 quarts from pan plug.
3. Pump in 3.5 quarts new WS fluid.
4. Check level hot with scanner.

In 19355 (King of Prussia area), shops charge $150-250. Sidekick tracks your mileage and alerts you. Based on Sidekick owner data from 1,200+ 4Runners, early service cuts repair risk by 25% (Sidekick Research Team, 2026 Q1 analysis, N=1,200).
