Translated from the manufacturer’s Safety Data Sheet, Section 8
SDS Section 8 recommends safety glasses with side shields when eye contact is likely, and Section 11 lists mild, short-lasting eye discomfort as a possible effect of this material. Section 2 carries no mixture-level eye-hazard GHS code, but the specific-use recommendation plus confirmed (if mild) irritation clear the bar for a recommended tier during pan removal and pour.
CarCareTruth publishes the cited sources verbatim and does not advise what action a user should take. Consult the full SDS before use.
Only when: splash risk
Translated from the manufacturer’s Safety Data Sheet, Section 8
Petroleum base stock contact is possible during pan removal and pour. SDS §2 mixture level: not classified for skin hazards under GHS. Situational tier reflects petroleum contact during the drain-and-fill service, not a GHS skin classification.

Only when: in enclosed space · hot panels
Translated from the manufacturer’s Safety Data Sheet, Section 8
SDS Section 8 only calls for respiratory protection at high airborne concentrations or with inadequate ventilation, standard language for a low-volatility fluid, and notes a supplied-air respirator only becomes relevant for mist formation. Section 2 carries no mixture-level inhalation hazard code. This is a ventilation precaution for draining hot fluid in an enclosed garage, not a mixture-level respiratory hazard.

California Prop 65 warning
This product's Amazon listing carries a California Prop 65 warning. The manufacturer's Safety Data Sheet (§15) does not list a Prop 65 substance for this product — we show the warning for transparency and flag the discrepancy rather than silently picking a side.
Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.
No warranties. CarCareTruth makes no warranties, express or implied, and expressly disclaims the implied warranties of merchantability and fitness for a particular purpose.

TL;DR Fully covers Dexron III, Mercon V, Allison C-4, and JASO 1-A, the right approvals for pre-2006 GM and pre-2008 Ford automatics. Not approved for Dexron VI, Mercon LV, Toyota WS, or ZF Lifeguard. No community shudder-resolution data was found for this specific fluid.
This synthetic-blend ATF is built for older GM and Ford automatics, the ones whose owner's manual calls for Dexron III or Mercon V. It's a straightforward drain-and-fill replacement, and it fully covers that spec family: Dexron III/IIIG/IIIH/IIE/IID/II, Mercon/Mercon V, Allison C-4, and JASO 1-A, verified on the manufacturer's product page. The synthetic base gives better low-temperature flow and oxidation resistance than a mineral-oil ATF built to the same spec. It is not approved for Dexron VI, Mercon LV, Toyota WS, or ZF Lifeguard: different specs for newer transmissions, not a gap in this fluid.
Right choice for owners of pre-2006 GM automatics needing Dexron III, pre-2008 Ford automatics needing Mercon or Mercon V, and applications requiring Allison C-4 or JASO 1-A; confirm the spec in your owner's manual before buying. Skip it if your vehicle requires Dexron VI, Mercon LV, Toyota WS, or any ZF Lifeguard spec: using the wrong ATF spec risks transmission damage.
The SDS classifies this fluid as not hazardous at the mixture level: no signal word, no GHS hazard codes. Take spent fluid to a used-oil collection facility; do not pour it down storm drains or into soil.
No. This product is designed for older GM automatics requiring Dexron III · the standard spec through the early-to-mid 2000s. Dexron VI is a different, more recent spec required by GM for most 6-speed and newer automatics from 2006 onward. Use a fluid with confirmed Dexron VI approval for 2006+ GM vehicles.
No. This product holds Mercon V approval, not Mercon LV. Mercon LV is Ford's low-viscosity spec introduced for 2008+ 6-speed automatics. Mercon LV and Mercon V are not interchangeable. Use a Mercon LV-approved fluid for 2008+ Ford vehicles.
It is the right fluid for pre-2006 GM automatics requiring Dexron III, pre-2008 Ford automatics requiring Mercon or Mercon V, and applications calling for Allison C-4 or JASO 1-A. Always verify your vehicle's owner manual spec requirement before purchasing.
It contains a PAO (polyalphaolefin) component (1-Decene homopolymer hydrogenated, 20-<30% per SDS §3), which qualifies the 'synthetic' label. The dominant base stock by volume is severely hydrotreated heavy paraffinic distillate (50-<60%), making this a PAO-containing synthetic blend rather than a pure PAO or ester-base ATF.
