Question

英语翻译
Harsh engagements and severe shifts while all shift speeds are okay.
Pressure Regulator “Force Motor” failure (See Figure 1).Extremely high
pressure will result.This cannot always be diagnosed with an ohms test as the
failure may be mechanical.
Replace the Pressure Regulator “Force Motor”.
A new Pressure Regulator from BMW is just under $600.00 and is usually
available in less than two weeks.There is,however,a suitable alternative that
has proved most effective.The G.M.4L80-E Force Motor is manufactured by
the same company and aside from a few minor differences does the same job.
Most of the overall dimensions are the same except that the G.M.4L80-E Force
Motor uses screens in the plunger and port areas (See Figure 2).Those
differences are insignificant.A new 4L80-E Force Motor will cost you about
$133.00.The G.M.part # is 8677314.
Pressure Regulator ohms test across both terminals should be 2.5 - 4.0 ohms resistance.
This ohms test should be done near room temperature.Do not energize this force motor
with full battery voltage as damage may result
Previously,unavailable valve body screens required that a complete valve body be purchased
Parts personel were unable to find the part numbers for the screens.
There are now part numbers available from Isuzu to service the valve body screens
individually.Refer to Figure 1 for the location of the Force Motor Screen and Figure 2 for the

Answer 1

可以承受全部档位时的猛力进档和退档.调压器“加力马达”故障（见图一）会出现极端高压.该故障用电阻测试法不能每次都诊断出来,因为这可能是机械故障.更换调压器“加力马达”.BMW一个新的调压器“加力马达”只要不到600美金并且不到两周即可到货.然而还有一种更有效的替代方法.同一工厂生产一种GM（通用汽车）的4L80-E加力马达,除了一些细小差别以外可以起相同作用.外形尺寸大都一样,不同之处仅在于通用汽车的4L80-E加力马达在活塞和喷口部位用了筛网.（见图二）GM的4L80-E加力马达只需133美元.GM的备件号是8677314.调压器两端测试电阻应该在2.5-4.0欧姆之间.电阻测试应该在室温下进行.不要对加力马达使用电瓶全电压,这会造成损坏.以前,丢失阀体筛网就得更换整个阀体总成,备件管理人员无法找到筛网的备件号.现在五十铃有了备件号,可以单独更换阀体筛网.加力马达筛网位置参见图一,转换阀体参见图二.加力马达筛网ISUZU 备件号 8-96041-009-0
