原文:(https://gm-techlink.com/?p=11127)Dealers should discontinue the use of the black label Mobil 1 Synthetic LV ATF HP fluid.
A communication from CCA will be released soon advising dealers of how to dispose of the old product.
The baseXSS stock of old fluid (19355656) has the ability to attract low levels of moisture, which can cause degradation of the coefficient of friction of the fluid.
The new fluid (19417577) has a new GTL (Gas to Liquid) baseXSS stock that is able to tolerate more moisture.
Shuddering transmissions and torque converters have been recovered with the new fluid.
New transmission fluid tests have been developed due this issue to prevent it from occurring with new transmission fluids.
可能是atf中的潮气影响了摩擦系数。旧款hp atf吸了少量潮气后,摩擦系数改变较大。新款hp atf 吸收少量潮气后,摩擦系数改变不大。
有文献提到:ATF要求动摩擦系数比静摩擦系数大。
