Abstract

The present disclosure describes transmission fluid compositions, additive packages, and methods for lubricating a transmission, particularly transmission fluid compositions having color stability. The transmission fluid composition is adapted for use in a transmission and contains base oil and an additive composition having either (a) a reaction product of a thiadiazole of one of the formulae (III) and (IV): <img class="EMIRef" id="473348860-ia01" /> wherein R<1>is a substituted or unsubstituted hydrocarbyl group having 1-100 carbon atoms; and a thiol of the formula R<3>-SH, wherein R<3>is a substituted or unsubstituted hydrocarbyl group having 1-100 carbon atoms, and optionally an additional sulfur source, or (b) at least one thiadiazole selected from compounds of the Formulas (I)-(II): <img class="EMIRef" id="473348860-ia02" /> wherein n is 1-5; R<1>is a substituted or unsubstituted hydrocarbyl group having 1-100 carbon atoms; and R<2>is a hydrogen or is a substituted or unsubstituted hydrocarbyl group having 1-100 carbon atoms.
