常见的治疗方法（Chrysler RWD）冷

记得旧的广告,“为什么贸易a headache for an upset stomach?”

它并不罕见transmissionrebuilds to find a fix for one problem that either creates or intensifies another problem.
就是关于每一个传输重建都看到克莱斯勒后轮 - 驾驶进入他的商店遭受了润滑油失败的影响。相同的单位可能也遭受延迟的接合。它并不罕见。这不是巧合。两者都是电路设计方式的结果。

Lube失败是如此普遍，即许多Rebuilders已经习惯于看到隐形的州长支持，查获的输出轴或圆形的太阳和行星齿轮，所有的润滑障碍迹象。这些故障可以追溯到冷却器/转换器电路以及压力调节阀的控制或馈送它。

Rebuilders have even come up with a “fix” to get around the problem. They have realized that the problem is this: The cooler/converter charge circuit won’t open until the pressure regulator valve moves far enough to flow oil, which means that the transmission is essentially running on empty until the pressure regulator valve is fully engaged. The “fix” is to drill a small orifice between the line pressure and cooler circuit to allow fluid to flow to the cooler/converter circuit, otherwise known as drilling line to lube.

But while this takes care of the headache, it inflames an already upset stomach called drainback. Drilling that small hole for line to lube does help the lube flow when the engine is running, but it increases converter drainback problems because ATF can drain out through the hole when the engine is turned off. While it is likely that drainback is already an issue in units with moderate mileage or more, it becomes a larger and potentially damaging issue when you add a circuit and provide more options for drainback flow.

Sonnax has developed a lube-regulated PR valve,22771A-02K，它允许油在发动机启动后立即流入转换器充电电路。一旦建立了足够的线条压力并且PR阀门开始馈送转换器/冷却电路，内部阀门关闭，并且设备正常运行。当单元关闭时，内部止回阀不允许流体通过孔口退回，减少转换器漏极。该钢阀将以低RPM和高压喇叭改善转换器进料。请记住，如果钻到润滑线的通道，你仍然可以做正确的事情。只记得堵塞孔，然后安装阀门。

While the PR valve was contributing to both the lube and converter charge problems, it had help on the converter charge or delayed engagement problem; the manual valve. The original manual valve design doesn’t allow the converter to be charged in park, which contributes to delayed engagements and potential converter bushing failure. You are not filling the converter until you pull it out of park so the delay is noticed as the fill begins after the lever is moved. If you have normal drainback, or worse, extra drainback from the line-to-lube hole, that converter filling delay becomes not only more of an annoyance but increases the risk of damage.

The Sonnax redesigned manual valve22771-09has a new control spool and circuit that provides converter charge in park. You don’t have to rework or adjust the valve body to install this valve, and it will not cause the forward clutch to drag in Park.

The Sonnax PR valve and manual valve are standalone parts that can be installed independently. The one-two punch they provide to cure two chronic problems is a most effective combination and we recommend they be used together whenever
可能。这些家伙也不只是在一些后期模型中工作。除了42到47 RH＆RE单位外，您还可以在大多数内安装它们727.要么904.或这些生成单位的变化。

规则很简单：始终看看原装压力调节阀的设计。如果内侧的线轴上的线轴逐渐变小（如圣诞树），您可以在该单元中使用我们的PR和我们的手动阀。如果原始PR阀的设计具有全部相同直径的端轴 - 而不是在末端变小 - 请勿在该阀体中使用我们的PR或我们的手动阀。

While you are in the valve body, don’t forget another player that often causes similar and additional problems: the line pressure plug and sleeve. Slippage in reverse, poor cooler charge at idle, poor line control and poor forward and reverse engagements are all symptoms of a worn line pressure plug and sleeve. When these parts wear, the PR valve can’t control line pressure properly. The solution is a Sonnax line pressure plug and sleeve kit, 12229-01K for the A904, or22229-01Kfor the A727,42RE,46RH和47rh.。袖子和插头允许PR valve完成工作，并可以节省数百人的阀门身体更换成本。
