Standard Specification for Performance of Manual Transmission Gear Lubricants
ABSTRACT
This specification provides a list of test methods and acceptance criteria for determining the performance acceptability of gear lubricants used in nonsynchronized heavy duty manual transmission (MT-1). The test methods listed here shall be able to examine the following properties of the gear lubricants: viscosity increase; pentane insolubles; toluene insolubles; carbon/varnish rating; sludge rating; hardness and volume change, and elongation of polyacrylate and fluoroelastomer; falling load stage; and foam tendency.
SCOPE
1.1 This specification lists the test methods and acceptance criteria for determining the acceptability of lubricants used in nonsynchronized heavy duty manual transmissions.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

3.1 Definitions of Terms Specific to This Standard:
3.1.1 nonsynchronized transmission, n—a transmission having no means for synchronizing the speeds of engaging elements.
Typical heavy-duty manual transmissions have no such means for gear engagement by the shift lever, but may have such means
for pneumatic engagement of auxiliary range gears.
3.1.2 oil seal compatibility, n—in lubricants for lubricating manual transmissions and final drive axles, prevention of chemical
or thermal degradation of seal elastomers typically observed as hardening, cracking, or excessive swelling in a manner which
would result in oil leakage.
3.1.3 thermal oxidation, n—in lubricants used for lubricating manual transmissions and final drive axles, deterioration of the
lubricant under high-temperature conditions which is observed as viscosity increase of the lubricant, insolubles formation in the
lubricant, deposit formation on the parts, or a combination thereof.
4. Performance Classification
4.1 API Category MT-1—The designation API Category MT-1 identifies the category of lubricants intended for use in
nonsynchronized manual transmissions, apart from API Service Category GL-4. See Appendix X1 for background information on
this category.
