新的传动流体交换程序和MOBIL 1合成LV ATF HP传输流体的新公式已释放到8L45和8L90 8速度自动变速箱（RPOS M5N，M5T，M5U，M5X上））在2015-2017 Escalade，Yukon;2015-2018 Silverado，Sierra;2015-2019 Corvette;2016-2018 CT6;2016-2019 ATS，CTS，Camaro;和2017-2019科罗拉多和峡谷模型。
The new fluid exchange procedure requires the use of the DT-45096 TransFlow Cooler Flush Machine and DT-52263 Transmission Fluid Exchange Tool Kit. (Fig. 10) The tool kit began shipping to dealerships at no charge in late January 2019. All GM dealerships should receive the tool kits by the end of March 2019.

颤抖的测试
当变速器不换档时，新的服务程序在光节气节加速度在25至80英里/小时（40和128km / h）之间的抖动和/或颤抖条件下。为了确保正确诊断TCC颤抖动，将车辆驱动到平滑的道路上，在122°F（50°C） - 158°F（70°C）之间的变速器槽温。需要在平滑等级上输入恒定的节流输入。
颤抖的条件也可以是牙垢，浪涌或振动条件。例如，使用GDS 2或CH-51450 PicoScope确认关注是TCC颤抖，而不是轮胎/轮振动或传动系振动。来自GDS 2的屏幕印刷或显示TCC颤抖事件的PicoScope必须附加到维修订单硬拷贝。（图11）
如果存在TCC颤抖，则振动峰值将在公告中列出的频率+/- 2 Hz内显示在公告中排名第18-Na-355中的频率。有关其他信息，请参阅公告，包括所诊断的每辆车所需的颤动测试条件以及流体交换程序。

流体交换
TCC颤动条件与变速器流体中的水分含量有关。目前的流体往往是含水性的，或吸收水分，这增加了TCC颤抖的机会。根据车辆应用，存在三种不同的流体交换程序，从而在变速器中实现了新的HP流体的可接受浓度。
The new Mobil 1 Synthetic LV ATF HP transmission fluid is now available to U.S. dealerships through your local GM Oil Distributor. The new Mobil 1 Synthetic LV ATF HP transmission fluid is available in quart bottles (GM Part Number 19417577) and, for a limited time, in 55-gallon drums (GM Part Number 19417904) (Fig. 12) in most locations. Drum production ended in January 2019. The GM part numbers are not on the product. The Mobil 1 Synthetic LV ATF HP fluid and the required tool kit will be available to all Canadian dealerships by the end of March 2019. GM Part Numbers for 0.946 liter bottles will be provided at that time.

小费：Mobil 1 Synthetic LV ATF HP transmission fluid is required for all 8-speed transmission repairs regardless of the repair being completed.
Quart瓶子可以通过瓶子前部的新蓝色横幅识别（图13），在新产品的初始发布期间每周每周限制20例/ 120夸脱。新瓶子还在背面标签上具有HP许可证号J-62120。应该停止使用黑色标签MOBIL 1合成LV ATF HP流体（GM部件号19355656）。

The old HP formula can be mixed with the new HP formula when completing repairs such as valve bodies, speed sensors etc. There’s not issue when intermixing the two fluids.
这种新油可以与油混合在没有转换器颤抖的卡车上的过滤器变化中，但只是有反式服务。
I have to agree with Jason Glover on this you only make the customer come back so many time and then they don’t come back at all, and as for the snap shot of the shudder that’s just a way for gm to charge it back to the dealership if its not done to what they like to see, anyone that’s been working on transmissions for any amount of time know what a convertor shudder is.
Mobil 1合成LV ATF HP传输应仅用于8L45和8L90自动变速箱。参考所有其他传输应用的适当流体的服务信息。
这种流体可以在6个速度纹理中使用，在光节水门输入中具有类似的鱼咬/牙垢/颤抖吗？
嘿杰森我同意我们在旧的冲洗中做得更多，但要意识到大多数互补工作没有得到正确完成。或者完全不是因为流行的信念，这不会解决它。– I actually got in trouble for flushing instead of replacing before all this broke loose -I think the time is good to do the flush but they need to add for documentation and have someone else drive with you so you don’t hit the wall trying to get a snap shot the thing with getting a fix and here is a good honest take on it you need to drive the vehicle after and verify its fixed if not you need to clock in go out and get the pico and the gds data upload it to tac after putting additional 200 miles on it” make you manager drive it for a week” , they will approve replacement if necessary. I have done 4 -55gallon drums and only 1 came back and did get a new converter there is a redesigned converter for the 45 series like the Colorado and ct6. if you go into the si forums you will find a lot of information and people willing to help.
马rshal, your dealership has the correct fluid. The product code and license number are correct.
我对这个新的流体感到困惑，需要一些帮助。
似乎没有人知道我在1月份收到的55加仑鼓中的传输流体，以及它是新的蓝色标签还是旧的缺乏标签Mobil 1 LV HP ATF合成液
label on the barrel says
packaged by 10118L18A

Its a grey barrel with blue print

I believe our parts manager has contacted someone but with no confirmed info.
此信息对我至关重要的是二手盆盆地的转基因经销商的2个Trans Builder。
我想提前感谢您的帮助。
经销商应停止使用黑色标签MOBIL 1合成LV ATF HP流体。CCA的沟通很快就会发布如何处理旧产品的经销商。
The base 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) base 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.
Our parts department contacted the local Mobil 1 rep because we are stuck with quite a lot of the black label fluid. the Mobil 1 rep told him that there is no difference between the black label product and the blue label product. Is this true?
It is not recommended to use any aftermarket fluid exchange machines. The procedure in TSB #18-NA-355 provides a new fluid concentration level of 93% or higher. Some aftermarket fluid exchange machines may not provide an acceptable concentration level of new fluid in the transmission.
Can you use another transmission flush machine.
The shudder condition experienced on the 8-speed transmission in most cases is torque converter clutch (TCC) shudder. However, in some cases, the shudder, fish bite, chuggle, surge or vibration is caused by something other than the torque converter clutch. That is why TSB #18-NA-355 is requesting a screen print of either a GDS2 Session showing TCC slip, GDS Special Functions showing TCC Locked, or a PicoScope screen print showing TCC shudder (vibration frequency). Duplication of a customer condition can vary from vehicle to vehicle and can also be influenced by environmental conditions. If you are experiencing difficulty in duplicating the shudder in the time allowed within TSB #18-NA-354, other labor hours (OLH) should be utilized and documented accordingly.
只是好奇，为什么我们需要为TCC颤抖提供文件。这令人担忧不是新的，毕竟这一次搞乱了旧流体（我也接受了更好的工资）我很确定参与这一点的每个技术人员都知道颤抖的感觉。我的问题是，我有一个带有CT6的客户，该客户已经有3次TCC颤抖。我们两次替换流体，第三次建议他常规修理即将来临。现在在俄亥俄州也很冷，所以我可能会觉得颤抖可能现在没有发生。如果我们致电这位客户并说修复出来，但如果您的汽车目前不发抖，抱歉您的运气。回来第四次，我们会照顾它。你觉得怎么样？我保证，如果我们这样做，因为客户的热情，索赔将被拒绝，我们目前没有DMA批准它。这次毕竟只是一个令人沮丧的情况。 This is just one example as we have several of these customers under this situation. Thanks for your time.
