2016 Ram ProMaster — Transmission Fluid & Service

Quick answer

• Transmission(s):
  • 3.6L V6 models: Chrysler 62TE 6‑speed automatic (FWD)
  • 3.0L I4 EcoDiesel models: M40 6‑speed automated manual (single‑clutch “Comfort‑Matic”)
• OEM fluid spec:
  • 62TE: Mopar ATF+4 (MS‑9602)
  • M40 gearbox: API GL‑4 75W‑85 manual transmission gear oil meeting Fiat/Mopar spec; actuator/hydraulic unit uses a dedicated hydraulic fluid — verify exact spec by VIN/owner’s manual
• Capacity (approx.):
  • 62TE drain & fill (pan drop + filter): ~5.0–5.5 qt (4.7–5.2 L)
  • 62TE complete/dry or after overhaul: ~8.7–9.5 qt (8.2–9.0 L)
  • M40 gearbox drain & fill: ~2.0–2.3 qt (1.9–2.2 L)
• Filter:
  • 62TE: internal pan filter and reusable pan or gasket; use OEM Mopar filter — verify correct part number with dealer or service manual
  • M40: no serviceable pan filter in the gearbox; the electro‑hydraulic unit may contain a strainer not serviced during routine maintenance — verify by VIN
• Recommended service interval:
  • 62TE: Normal duty 60,000 mi (96,000 km); Severe/towing/urban delivery 30,000–40,000 mi (48,000–64,000 km)
  • M40: Normal duty 60,000–90,000 mi (96,000–145,000 km) for gearbox oil; Severe 30,000–45,000 mi (48,000–72,000 km). Actuator fluid only by time/condition or if repairs are performed, per service manual

Fluid type explained

• 62TE automatic: This unit requires Chrysler‑licensed ATF+4 only (MS‑9602). Do not substitute Dexron/Mercon or “universal” ATF unless it explicitly states ATF+4 approval. ATF+4 provides the correct friction characteristics for the torque converter clutch and the 62TE’s solenoid/valve body calibration.
• M40 automated manual (diesel only): The transmission is a conventional manual gearbox with an electro‑hydraulic module that operates the clutch and shifts. Two fluids may be present:
  • Gearbox oil: API GL‑4 75W‑85 (do not use GL‑5 unless approved by Fiat/Mopar, as GL‑5 can be aggressive toward yellow metals in synchronizers). Use a product meeting the Fiat/Mopar spec listed in your owner’s/service manual.
  • Actuator/hydraulic fluid: A specific hydraulic fluid (e.g., a Tutela/CS‑Speed‑type or equivalent as specified by Mopar). This is not ATF. Only service or top off with the exact fluid specified by part number/VIN.

Always confirm by VIN in the dealer catalog if you are unsure which transmission your ProMaster has.

Service procedure

62TE automatic — drain & fill (recommended routine service)

1. Warm the transmission to operating temperature, then raise the van level and safely support it.
2. Remove the pan bolts, carefully lower the pan, and drain the fluid. Expect ~5–5.5 quarts.
3. Clean the pan and magnet. Replace the internal filter and pan gasket/seal (use OEM). Torque pan bolts evenly to spec.
4. Refill through the fill tube on top of the transaxle with Mopar ATF+4. Start with the amount drained.
5. Level setting: With a scan tool, monitor trans temp and use the service‑dipstick tool and temperature chart (Chrysler special tool) to set the fluid level precisely. If you don’t have the tool, match the drained volume, then have the level verified by a shop.
6. Road test, then re‑check for leaks and re‑verify level at temperature.

62TE — full exchange/overhaul fill

• If fluid is severely burnt/contaminated, avoid power “flushing.” A fluid exchange via the cooler lines or multiple drain‑and‑fills is safer. After a rebuild or when dry, total capacity is roughly 8.7–9.5 quarts, but always set level by procedure/temperature, not capacity alone.

M40 automated manual — gearbox oil service

1. With the van level, remove the gearbox fill plug first to ensure it will open.
2. Remove the drain plug, allow oil to drain completely, reinstall with a new sealing washer if required.
3. Fill with GL‑4 75W‑85 until fluid is at the bottom of the fill hole or to the capacity listed in service information. Reinstall the fill plug and torque to spec.
4. The electro‑hydraulic actuator fluid is not routinely serviced unless repairs or contamination are present. If service is required, follow the factory procedure, use the exact specified hydraulic fluid, and perform clutch/shift relearns with a scan tool.

Service interval

• 62TE automatic:
  • Normal service (mixed highway, moderate load): Replace ATF+4 and filter every 60,000 miles or 6 years.
  • Severe service (frequent stop‑and‑go, heavy payloads, hot climate, towing, or parcel delivery duty): 30,000–40,000 miles. Inspect cooler lines and consider adding an auxiliary cooler if operating temps are high.
• M40 automated manual:
  • Gearbox oil: 60,000–90,000 miles normal; 30,000–45,000 miles severe. Replace sooner if water intrusion or debris is suspected.
  • Actuator/hydraulic fluid: Inspect by time/condition; replace only per factory procedures or when components are serviced.

Common transmission problems (2014–2018 ProMaster)

• 62TE automatic:
  • Overheating and fluid breakdown under heavy loads; leads to torque converter clutch shudder or slip (P0740/P0741) and accelerated wear.
  • Harsh or delayed shifts from valve body/solenoid pack wear; software updates and correct ATF+4 level help. Aged mounts can amplify harshness.
  • Premature clutch or converter failure if wrong fluid is used or level is off. Always verify fill by temperature.
  • Cooler line seepage and pan gasket leaks; inspect during service.
• M40 automated manual (diesel):
  • Clutch wear and judder in heavy stop‑start delivery routes; requires clutch replacement and actuator recalibration.
  • Actuator/hydraulic module faults causing no‑crank/no‑shift or limp mode; may require software updates, bleeding, or module replacement.
  • Shift hesitation or gear engagement errors if battery voltage is low or adaptations are out of range; perform relearn/calibration with a scan tool after repairs or battery disconnects.

Note: Capacities are approximate; always set level by the factory method and verify part numbers/specs by VIN or the service manual.
