转换器难题

Bob Warnke

conundrum =涉及双关语的谜语

2010年前3个转换器与传输问题

Conundrum 1.

应用程序：
  • 梅赛德斯00到2012年
  • Sprinter
  • 躲闪
  • Jeep
  • Freightliner
投诉：
  • 发动机在凉爽的温度下绊倒（气体或柴油）
  • 凉爽时粗糙闲置
  • Driveline vibration ( NVH) during TCC modulation
  • TCC shudder or drone between 35-48 mph
Cause:
传输相关：
  • 转换器压力泄漏到TCC活塞区域
  • Low converter apply pressure, due to valve bore wear
  • Defective TCC solenoid
Converter Related:
  • TCC lining flake, due to water or Glycol
  • TCC离合器间隙和摩擦材料
更正：
  1. 空气测试传播和阀体电路(见下面的细节pages).
  2. Visual or vacuum test the working pressure regulator, the lube/converter limit, the torque converter control and the TCC damper piston.
  3. 测试，替换Y3锁定电磁阀。
  4. Refer to Glycol test kit.
  5. The TCC piston must return to release the converter clutch. A problem arises when centrifugal force reacts on fluid trapped behind the clutch piston. The residual pressure plus the force walks the piston toward the clutch. Within the 722.6 converter, oil trapped behind the TCC piston cannot be vented. This problem is increased by charge pressure of 50-100 psi. working its way into the low pressure TCC circuit. Fluid from the valve body to pump stator can exhaust at the control valve, but fluid trapped behind the piston loads it toward the clutch.
Alternatives:
  • 迫使活塞释放
  • 使用更高的流量摩擦板
Air Testing
1。The TCC apply circuit can be air tested, (30-60 psi.) with the unit in the vehicle and the valve body in place. Charge the exhaust hole. The air supplied will push remaining fluid into the converter TCC piston. Minimal leakage should come out cooler lines or other valve body locations.
如果移除阀体，则可以隔离三个转换器电路。转换器充电或转换器的任何泄漏都来自泵或转换器内的交叉泄漏。
笔记：Teflon®型密封环需要液体升力。如果空气测试用干电路，它们会交叉泄漏。涡轮轴密封环应为OE重叠设计。阀体必须平坦，应消除泵定子或转换器交叉泄漏。内部传动衬套确保涡轮轴运行真实，要求戒指密封。
The turbine shaft can also be installed into the converter and the clutch tested as well.


2。Low converter apply pressure extends from the main/working pressure regulator bore and the Lube/converter limit valve. Wear at either area affects TCC and converter charge psi. Critical wear points within circles (shown in photos below.) The TC control valve must stroke for full apply. Bore wear at either location reduces the TCC solenoid's ability to stroke the valves.


3。The normally closed, Y3/ 6y6, TCC solenoid strokes the torque converter lockup valve. If the Y3 solenoid leaks into the control valve circuit, the valve may rest in a partial apply position.

Converter Related:
4.在ATF中测试水或防冻剂。在一些应用中，一滴足以降解离合器衬里。

Mercedes kit # 000-989-009 and 000-989-0014
ESP Chemicals Inc. Ph; 520-622-4087 #HI 3859 @ $75.00
Chrysler cannot cross reference this number.
An alternative is to use a hot plate and check for a sizzle noise as the water burns off.

5。积极的转换器摩擦板，较差的涡轮轴飞行员和/或活塞返回缺乏可以产生这种情况。

Conundrum 2.

应用程序：
  • 奥德赛
  • Similarities to other 4-speed designs
Complaint:
  • TCC滑动码
  • No TCC apply
  • 过热的转换器
Cause:
  • Valve body bore wear
  • Restricted Coolers
  • 有缺陷的线性螺线管
  • Converter hub O-rings too small
更正：
1。主要控制体孔磨损（圈子临界点）。
控制阀体在转换器浮雕孔上佩戴。要在拆卸之前隔离，请将扫描仪数据与冷却器进行比较。您应该看到TCC命令和安培数与Sonnaflow®上的冷却流程更改平行。
TCC或TCC滑移的损失：通过在TCC控制阀处松开的端塞产生。转换器电荷油进入TCC控制的交叉泄漏对TCC控制产生负面影响。检查成品区域的交叉泄漏的定子，通过铸件。

2。受限制的冷却器在液压系统上产生背部压力，慢速阀门慢速慢慢地阻止它停止中间行程。
其他4速的本田具有类似的冷却流程图。

康普拉姆3.

  • Aisin Warner 6速度，前轮驱动
应用程序：
Complaint:
  • Harsh shift (relative to converter release)
  • 过热的流体
  • TCC骑自行车，RPM波动
  • 没有移动，没有力量
Cause:
  • TCC control valve bore wear. The converter is opened briefly during upshifts and some downshifts. If the clutch does not release, the shifts are very firm. The lack of release can be valve, solenoid or converter related.
  • Primary and secondary regulator valve bore wear. The feed for converter apply and release starts at the main regulator which then feeds the secondary regulator valve. Both of these bores are known to wear. This wear positions the valve in a low flow state, reducing converter feed and lube.
In-Vehicle testing:
It is possible to isolate the Electro-Hydraulic control over the converter clutch.
用扫描仪;监控TCC电磁阀。您应该看到加速度发生变化，因为它会简单地调制以打开转换器。
压力表;点击TCC发布。您应该在扫描仪识别Amperage命令的同时看到控制阀笔划。

TF-60SN / 09G
更正：
1。Visual inspection, WAT or vacuum test the TCC control bore at the inboard end and the outboard sleeve. If worn, ream or replace the valve body. Aftermarket valve body rebuilders generally have these in stock.


TF-80SC / AF 40 / AM6



TF-81SC / AF21



TF-60SN / 09G


What’s Coming:

722.98-Speed:
OE information notes:
  • The torque converter is the same as the 722.6 with the addition of a turbine damper.
  • 722.6，在一些道奇应用（300 magnum）中有一个阻尼器组件。
  • 722.9，被指出具有开放式高流量转换器。在TCC滑动期间，流动将减少。我们认为这是由于TCC控制阀的位置。
  • It can/ will be slipped in all 7 gears, with the intention not to go 1:1. It will generally be open in 1st and 2nd gear.
  • The last year of the 722.6 will be 2012.
  • 722.9 requires special fluid is required; Shell or Fuch’s, ATF 3353, MB# AOO1 989 45 03 10.
Ford 6R140:
  • F-350卡车。6.7 DSL，6.2 LTR气体
  • This 6-speed unit has a PTO, which is driven off the inner pump gear. The inner gear drives the PTO idler, which is supported by the pump stator bearings.
  • Ford noted the design requires a close tolerance control over converter hub runout.
  • 转换器具有封闭的活塞转换器离合器，与变速器壳体内的盘形活塞相当。
ZF 8:
OE information notes:
  • TCC在第二档之后涂抹并保持在。通常，这些离合器在升档期间短暂地打开。在某些情况下，它们不会被调制/打开，以减少换档的持续时间，提高驾驶能力和经济性。
  • Appears ZF continues the use of tabbed multi-plate with two-circuit fluid path and the release oil exiting from the turbine shaft.
DCT:
  • 干式离合器，双阻尼输入离合器
  • Replaces torque converter and/or wet clutch
  • Ford will have a substantial production number of these dry clutch transmissions.
Honda 6-Speed:
  • Multi-plate converter clutch for expanded torque capacity and lower speed modulation. TCC can be applied from 20 kmh / 12 mph upward.
  • 盖子具有独立的浮动活塞，具有多板开槽摩擦。
  • The operation could be compared to the RE5R05A or 722.6.
