Transmission Fluid Service Checklist

This transmission fluid service checklist ensures proper fluid selection, condition assessment, and service procedure for automatic, CVT, and dual-clutch transmissions per OEM fluid specifications and transmission manufacturer service requirements. Designed for transmission technicians to prevent costly misapplication errors from incorrect fluid types and document all service procedures. Perform at manufacturer-specified intervals or whenever fluid condition indicates service need.

Industry: Automotive Service
Frequency: Every 30,000-60,000 miles or per OEM spec
Estimated Time: 30-60 minutes
Role: Transmission Technician / Service Technician
Total Items: 28
Compliance: OEM ATF Specifications (Dexron VI, Mercon LV, ZF Lifeguard, CVTFplus), JASO M315 CVT Fluid Standards, GM Dexron VI Fluid Specification, Ford Mercon LV/ULV Specifications, ZF Transmission Service Standards

Fluid Condition Assessment

Evaluate ATF condition to determine appropriate service. Fluid condition dictates whether flush, drain-and-fill, or pan service is needed.

ATF color assessed - not dark brown/black or burnt-smelling?
Dipstick or sample check shows no metallic particles or heavy contamination?
ATF level correct on dipstick at operating temperature?
No signs of water/coolant contamination in ATF (milky/foamy)?
OBD-II scan for active or pending transmission fault codes performed?
Transmission cooler lines and fittings inspected for leaks?

Fluid Specification Verification',

Critical: verify correct ATF specification before service. Using wrong fluid type causes severe and immediate transmission damage.

Correct ATF specification verified from owner's manual, dipstick label, or OEM lookup?
'Universal' ATF confirmed to meet required specification (not just any universal fluid)?
Correct fluid quantity documented (capacity and refill amount)?
Correct fill port location confirmed (transmission fill differs from check dipstick on some vehicles)?
New ATF verified from sealed, uncontaminated container?

Pan Drop & Filter Service (if applicable)

Procedure for pan-drop service including filter replacement, pan gasket, and magnet cleaning.

Transmission pan inspected for debris accumulation type and quantity?
Pan magnet(s) cleaned and inspected - normal metal accumulation only?
New transmission filter installed per OEM specification?
New pan gasket or RTV sealant applied correctly per OEM procedure?
Pan bolts torqued to specification in star pattern?

Post-Service Verification & Level Check

Verify correct ATF level and operation after service. Incorrect level causes transmission failure.

ATF level rechecked at correct temperature per OEM procedure?
Vehicle test driven and inspected - no leaks from pan or cooler lines?
Transmission shift quality smooth through all gears after service?
Used ATF disposed of per EPA used oil regulations?

Service Documentation & Next Interval',

Complete documentation and communicate next service interval to protect customer investment.

ATF product name, specification, and quantity documented on repair order?
Next transmission service interval (mileage and date) noted for customer?
Customer advised of fluid condition found and service performed?
Transmission filter part number documented on RO (if filter was replaced)?
Any drivetrain warranty considerations noted (fluid affects powertrain warranty)?
Customer advised transmission may need adaptive relearn period after fluid change?
OBD-II scan performed after service to verify no transmission fault codes set?
Post-service test drive completed through all gears and customer report positive?
