function and Role⢠of Transmission Oil in Whirlpool Gearcase Assemblies
The transmission oilâ in a âŁWhirlpoolâ gearcase creates and maintains⣠a⣠lubricating film on the worm gear, pinion, bearingsand bushings so â¤gear teeth slide â¤rather than âŁgall âŁunder load.⣠The OEM product 350572 âwhirlpool Transmission Oil 15 Oz contains a blendâ of base oil⤠and âanti-wear, anti-foamand corrosion-inhibiting additives formulated for the gearcase’s metallurgy and elastomers; this âformulation preserves film strength at the operating temperatures and shearâ rates typical of a domestic washer transmission. Using âthe specified fluid avoids incompatibilities that can accelerate wear on bronze or âbrass wormâ wheels, degrade seal materialsor change frictional behavior that affects agitation⤠and spin performance.
- Primary functions:⤠friction reduction, heat dissipation,⢠corrosion protectionand contaminant suspension.
- Behavior under load: viscosity must remain stable to â¤prevent metal-to-metal contact during high torque âcycles.
- Compatibility concerns: choose fluids⤠matchedâ to gearcase metallurgy and sealâ elastomers; avoid automotive âŁgear oils â¤with extreme-pressure â¤additives that can harmâ certain⤠seals.
- Serviceâ indicators: contaminated or low â¤oil⤠often produces grinding, increased noise, elevated running temperatureor metal particles in drained oil.
In practice,⢠a 15 oz service bottle is sized to refill or top off many âWhirlpool gearcases after drain-and-inspect⣠maintenance; technicians should drain âŁthe âgearcase, inspect for â˘metal debris, â¤and⤠refill âto⢠the manufacturer’sâ specified level using the specified fluid to preserve designed gear clearances and bearing film thickness. âForâ field diagnostics,measure oil condition âŁ(color,viscosity,presence of âparticulates)â and monitor â¤operating temperature and noise; if contamination âŁor degraded viscosity is detected,replace the oil and inspect for⤠root causes âsuch as âfailing bearings or compromised⤠seals toâ prevent âŁrepeated â˘failures.

How the 350572 Whirlpoolâ Transmission Oil 15 â˘Oz Circulates, lubricatesand Protectsâ Internal âŁDrive âComponents
The transmission oil in a Whirlpool gearcase is delivered into the sealed sump and dispersed⢠by the rotating â˘gears andâ shaft splashes; 350572 Whirlpool Transmission âOil⤠15 Oz â˘is supplied as a service refill âsized for that⣠gearbox â¤volume. Asâ the âgears rotate, centrifugal action and gear tooth meshing force create â¤a circulating flow thatâ wets bearings, bushingsand tooth flanks. Under normal âoperating clearancesâ this oil establishes a thin hydrodynamic film between metalâ surfaces that carries⢠load, reduces asperity contactand damps vibratory motion. âThe âformulation is chosen to⢠be compatible with the gearbox elastomers âand â˘injection-molded plastics used in Whirlpool transmissions,minimizing swelling or hardening of seals while maintaining⤠stable viscosity across the âwasher’s typical⤠temperature range.
Beyond forming a lubricating film,the oil âperforms heat transfer and âŁcontaminant âmanagement functions: it conducts âŁheat away from gear âŁmesh zones,carries suspended wear particles âto lower-speed sump areas,and contains additives that âlimit corrosion and foaming.â During service, âŁtechnicians should look for increased gear noise, harsh agitation âcycles, â¤or visible metal flakes⢠as⤠indicators of oil degradation or contamination;â a refill⢠using the correct part during gearcase⤠rebuilds restores intended film thickness and seal conditioning. Practical service steps include⤠draining and inspecting the oil for water or debris, replacing the fill to the OEM level,⤠and verifying that the âtransmission operates quietly through a â˘complete agitation cycle.
- Hydrodynamic film formation to separate slidingâ and⣠rolling surfaces
- Heat dissipation â¤from gear mesh and bearing interfaces
- Seal⢠conditioningâ to preserve elastomerâ adaptability and prevent leaks
- Suspension and settling of wear particles for easier âinspection during service

Common⢠Failure Symptoms âŁand Diagnostic Indicators of Worn or Contaminatedâ transmission Oil
Transmission oil that has become worn or contaminated degrades⢠the intended lubricating, hydraulicand particulate-suspension properties of a âwasher transmission. in many Whirlpool assemblies the⣠OEM fluid specification controls viscosity, anti-wear additives,⤠and â˘detergency; replacing or topping up with the correct product (for example, 350572 â¤Whirlpool Transmission âOil 15⤠Oz) returns âtheâ assembly to it’s designed fluid characteristics â˘whenâ performed according to the service procedure.⣠Mechanically, degraded oil raises friction, accelerates⢠gear and bearing wear, increases clutch slip and heat generationand can foul âŁvalvesâ andâ solenoids – symptoms âthat change the expected â˘behavior âofâ shifting, torque transferand motor â¤loadâ underâ typical cycle conditions.
- Dark⣠or blackened oil with aâ burnt or acrid â˘smell
- Presence â˘ofâ metallic particles orâ gritty⣠residue in the sump or âmagnetic plug
- Foaming, milky appearanceor free water â˘indicating contamination
- Delayed or erratic clutch âŁengagement and intermittent gear slipping
- Elevated operating temperature and⣠increased noise or â˘vibration during âspin/load
| Item | Description |
|---|---|
| Color⣠& Odor | Normal:â lightâ amber, neutral smell.Contaminated: dark brown/black, burnt odor. |
| Particle Content | Normal: few to no particles.⤠Contaminated: âvisible metallic flakesâ or high particulate load on drain⤠sample. |
| Behavioralâ Indicator | Normal: consistent âŁshift timing âand torque. Contaminated: delayed shifts,â slipping, increased motor current. |
Diagnosing worn orâ contaminated fluid requires both visual/olfactory checks and measured tests: collect a⣠drain or dipstick sample for inspection, check the magnetic⣠plug for ferrous debrisand if available⤠perform particle count or ferrographic analysis to distinguish wear metals fromâ dirt. Measure operating temperature â¤and compare motor current or amp draw under aâ standardized load to baseline values; increased steady-state⢠temperature or elevated amp draw alongside contaminated fluid⣠points to reduced lubricity or clogged âŁhydraulic passages. Practical remediation depends on diagnosis-flush and replace with an OEM-spec fluid, inspect filters and seals â¤for ingress⣠sourcesor disassemble the transmission⢠if critically important â˘metal wear or valve-body fouling⢠is present.

Q&A
What is 350572 Whirlpool Transmission Oil 15 oz â˘and what is it usedâ for?
350572 is âa manufacturer-specified â˘transmission/gearcase lubricant âsupplied in a 15-ounce tube. It is âŁformulated to âlubricate the gears, bearings and seals inside theâ gearbox (transmission/gearcase) of âŁcertain Whirlpool-family washing machinesâ and similar⤠appliances during service or rebuilds. It is not â¤intended for automotive transmissions or engines.
Which machines is this oil compatible with?
Compatibility depends on the transmissionâ model âused âinâ the appliance.â The safe way⢠to confirm compatibility is to check theâ appliance’s service manual or parts list for â¤part⢠number⤠350572 (or the OEM lubricant specified for the transmission/gearcase). Many Whirlpool-, Maytag- and Kenmore-branded washers that use service-replaceable gearcases specify an OEM transmission lubricant; check âthe exact transmission/gearcase âpart number before using.
How â˘much â˘oil is in the tube andâ how much do âŁI need to service a⢠transmission?
The tube contains â15 ouncesâ (by volume)⤠of lubricant. How muchâ is required varies byâ transmission model – some gearcases require only âa few âounces for â˘a top-up, while a full rebuild may take a larger quantity. The 15 oz tube â˘is typically sized âto service â˘at âleast âone transmission, âbut always follow the service manual for the specified fill⤠level.
What is the correct procedure to apply or refill this transmission⣠oil?
General safe steps: unplug the⣠appliance and, if applicable, disconnect water and power.Access the transmission/gearcase per the service manual, place a âcatch pan for any old lubricant, remove⤠the âfill/drain plugs,â drain the oldâ oil if replacing, then refill to the level or â¤quantity âspecified by the manufacturer using the âŁ15 ozâ tube or a syringe/dispensing tool for accuracy. Reinstall and torque plugs perâ the âmanual, check for leaks, reassembleand run a test âcycle. Always follow the appliance service manual for âmodel-specific instructions and safety precautions.
Can â¤I substitute this oil with automotive transmission fluid, motor⤠oilor âŁhousehold greases?
No. do not substitute arbitraryâ automotive fluids,â motor oilsor household greases without confirming compatibility. Applianceâ gearboxes use lubricants⤠chosen for the gearbox design, operating â¤speed,⢠load â¤and seal materials.Using the OEM-specified lubricant (or a manufacturer-approved equivalent) prevents premature wear â¤and seal damage.⤠If youâ cannot obtain â¤part 350572, consult the service manual âor manufacturer to âidentify an approved option.
Will â¤adding this oil âŁfix⢠a noisy or slipping transmission?
Adding or replacing transmission oil â˘can reduce noise caused by inadequate lubrication and may restore smoother operation when â˘the âŁgearbox isâ simply low or contaminated. However, ânoises or slipping can⤠also be caused by⤠worn gears,â bearings, clutch componentsor broken parts; lubrication will not repair mechanicalâ damage. Diagnose âŁtheâ cause (inspection during disassembly)â before assuming oil alone will fix the problem.
Are there any safety, handlingand disposal precautions I should â¤follow?
Treat theâ lubricant as you⢠would other petroleum-based shopâ fluids: avoid⤠skin and eye contact (use gloves and âŁeye âŁprotection), keep away⣠from heat/open flame, âand store in âa âŁcool, dry place.â Do not pour used lubricant down drains. Collect used oil and contaminated rags and dispose of them in accordance with⣠local hazardous-waste regulations orâ at a designated recycling/drop-off location.
How should this product be stored and how can I âŁtell if it âhas gone âbad?
Store sealed tubes in⢠a cool,â dry area âaway⣠from direct sunlight and sources of⢠ignition.â A sealed tube hasâ a long stable shelf life; however, if the âlubricant⣠isâ discolored, separated, contains âparticles, has a rancid odoror⣠has been contaminated with water or detergents, it should⤠not be used. If in doubt, replace with â˘a freshâ OEM or approved equivalent product.
