棒球、螺线管和苹果派:触及甜Home Run with 55-50SN Rebuilds

Summer is upon us, which means warmer temperatures, baseball, solenoids and apple pie. Yes, that’s right: solenoids. “What do solenoids have to do with summer, baseball and apple pie?”, you’re probably wondering. Hang in there!

A common saying from the coach to his team on the field is, “Know what you’re gonna do with it.” That’s his way of reminding players to think about the situation. If there’s one out, a runner on first and the shortstop gets the ball, players should know to go to second for the force out with the hopes of turning a double-play at first. Thinking that through before the ball is hit increases the player’s reaction time and – consequently – the chances of a successful outcome. Of course, knowing how the game is played is integral to deciding what the best play IS, not to mention what moves to make.

The Lineup

首先是蝙蝠：控制扭矩转换器离合器的施加和释放的SLU电磁阀，第二（B2）离合器和低和反向（B3）离合器。乐动BBIN彩票硬或柔软的1-2和2-1班次，公司/晚期TCC应用，早期TCC应用或没有转换器锁定均可归因于有故障的SLU螺线管。One away!

Next up: the SLT solenoid that primarily controls line pressure in accordance with engine torque at the primary regulator valve. SLT pressure also is directed to the secondary regulator valve to control converter feed pressure and feed the lube circuit. In addition, SLT pressure influences the forward clutch, second coast clutch and 3rd gear band. A multitude of symptoms could occur from a faulty SLT solenoid: harsh/delayed Neutral-to-Drive, harsh Forward, long shifts, low cooler flow, harsh TCC apply, and 2-3, 3-2, 3-4 and 4-3 shift complaints.下来！

最后的蝙蝠：通过调节换档压力控制阀处的驱动器或反向流体来控制第二离合器，第二沿海离合器或直接离合器，控制离合器的SLS螺线管通过调节驱动器或反向流体来施加压力。这意味着有故障的SLS螺线管可以产生严苛的反向和苛刻/辐射2-3,3-4,4-5班次。同样的症状可能是由一个以上的螺线管发出引起的，在根本上进行诊断引起粘性。三个下来，现在家庭团队来到盘子里！

Hit a Home Run with Sonnax Remanufactured Solenoids

SONNAX提供55-50秒的再制造线性螺线管，不仅可以解决粘贴衬套，而且还有一系列其他潜在的失效模式，导致相同的驾驶性问题。Sonnax通过独特的新设计改进了衬套，该设计采用了更好的材料，尺寸适合完美合适的尺寸和完成，即使在高温下也抵抗粘附。Base-hit, man on first!

Wear between the solenoid valve and “snout” can result in loss of the critical SLU, SLT, SLS or solenoid modulator pressure, leading to various shift symptoms (图2). Sonnax addresses these concerns by running every solenoid through a rigorous drive-cycle style test on a valve body test machine to ensure that excessive clearance is not occurring and reducing critical pressures.Single up the middle, men on first and second!

电磁阀和“鼻子”之间的磨损可能导致临界SLU，SLT，SLS或电磁调节剂压力损失，导致各种换档症状。

Another potential failure mode is relaxation or coil binding of the internal solenoid spring. Sonnax tests every solenoid for concerns in this area too by verifying that the spring is providing the appropriate force to help correctly position the solenoid valve.耀斑超过3，底座加载！

Finally, one of the most difficult and time-consuming issues with these linear solenoids is adjusting the pressures. By turning the adjustment screw inward or outward, the spring force on the valve is altered, which increases or decreases the SLT, SLS or SLU solenoid pressure. Because these solenoids are so interdependent, small adjustments can affect many areas in the drive cycle. Getting each properly adjusted to the now-aging传播并且与阀体，离合器等的任何其他校正都没有容易的任务。Sonnax通过在跨车辆平台上工作的每个电磁阀上的预校准设置来解决调整困境，在安装后消除在商店的耗时调谐（图3.).Grand-slam!

Sonnax pre-calibrates the 55-50SN remanufactured solenoids to precisely match OE performance, eliminating the need for tuning after installation.

除了完全测试和校准的线性螺线管外，Sonnax还为各种转变问题提供了全阵列55-50sn解决方案，包括55-50sn Zip套件，该试剂盒解决了最常见的问题，而无需铰孔。现在像一块温暖的苹果馅饼一样甜蜜，用一些香草冰淇淋！
