故障现象 一雪佛兰子弹头轿车(自动变速器型式为4T60型),先前由于自动变速器摩擦片烧蚀,在某修理厂更换摩擦片后,出现换挡冲击现象,后陆续在一年多时间经几家修理厂诊治,该现象始终未消除。故障分析 自动变速器换挡冲击故障是自动变速器中较棘手、较复杂的一类故障,它涉及面广、故障点多,排除难度大。其中影响换挡冲击故障的因素主要包括以下三个方面:一是机械方面的故障,如自动变速器摩擦片装配间隙不合适、卡簧装配不到位等;二是油路故障,如节气门拉线调整不当、阀体中的钢球错位、蓄压器油压调整
Symptoms of a Chevrolet bullet sedan (automatic transmission type 4T60 type), previously due to automatic transmission friction plate ablation, friction plate replacement at a garage, the shift shock phenomenon, after another in more than a year after several Repair shop treatment, the phenomenon has not been eliminated. Failure Analysis Automatic transmission shift shock failure is more difficult in automatic transmission, a more complex type of fault, which covers a wide range of fault points and more difficult to eliminate. One of the factors that affect the shift shock failure include the following three aspects: First, mechanical failures, such as automatic transmission friction plate assembly gap is not suitable, circlip assembly is not in place; the second is the oil fault, such as throttle pull adjustment Improper, the steel ball in the valve body is dislocated and the pressure in the accumulator is adjusted
