故障现象:
Fault phenomena:
客户反应他的别克车在行驶30000km后,突然感觉到没有刚买时那么动力十足,连车库入口处一个很小的坡道都爬不上,非要猛踩油门到3000r/,才能勉强爬坡,另外车辆起步到达中高速80~90km/h后,再往上提速就很困难。
Customers responded that his Buick was driving 30,000 km, and suddenly felt that it was not as powered as it was when he first bought it. Even a small ramp at the garage entrance could not climb, so he had to slam the accelerator to 3,000 r/, to climb the slope reluctantly. In addition, it was very difficult for the Buick to climb up again after starting at 80-90 km/h of the medium-high speed.
故障检查:
Fault check:
将挡位挂到空挡“N”,加油门,发动机转速能达到5000~6000r,且发动机运行声音正常,发动机无故障。
Put the gear into neutral "N" and the accelerator, the engine speed can reach 5000-6000r, and the sound of the engine is normal, and the engine is trouble-free.
将车子用举升机抬起,挂到各个前进、后退挡位,踩下油门,车轮都能正常转动,用接杆听变速箱左右两端轴承处,没有发现异响声音。将接杆放到变扭器处的主动链轮支架轴承处检查,也没有异响,整个变速箱没有特别异常的声音。将变速箱与发动机接口处的防尘罩取下,在停车挡时检查变扭器的温度,属于正常范围。
The car is lifted by a lifter, hung to the forward and backward gears, stepped on the throttle, the wheels can rotate normally. The connecting rod is used to listen to the bearings at the left and right ends of the gearbox, and no abnormal sound is found. Place the connecting rod at the bearing of the active sprocket bracket at the torsion converter for inspection, and there is no abnormal sound in the whole gearbox. Remove the dust cover at the interface between gearbox and engine and check the temperature of the torsion converter when stopping, which belongs to the normal range.
将车放下,拉出自动变速箱的油尺,发现油质稍微有一点点深色且有淡淡的油焦味,但还属于正常状态。
Put the car down and pull out the oil ruler of the automatic transmission. It is found that the oil is slightly dark and has a slight smell of tar, but it is still in normal condition.

将车开到车间外一个小坡处,挂上挡,松开刹车踏板,车子竟然没有动,加油门到3500r/min,车子开始慢慢起步,再将挡位挂到1挡,不加油松开油门踏板,车子还在原地不动。将挡位挂到倒挡“R”,出现同样的情况,只有猛踩油门车子才会移动。
Drive the car to a small slope outside the workshop, hang up the gear, release the brake pedal, the car did not move, the accelerator to 3500 r/min, the car began to start slowly, and then the gear to gear up to one, unload the accelerator pedal, the car is still in place. When the gear is shifted to reverse gear "R", the same situation occurs, and the car will move only when it slams on the accelerator.
  检查TECH 2中的DTC故障码,发现有两个故障码,分别是P0756、P0758,汽修资源微信1106037754此为2-3换挡线圈功能性缺陷和电气故障。在行驶中用TECH 2检查变速箱运行时的各项数据:1-2挡的换挡时间正常,2-3挡的换挡时间是2.5s,大大超出正常范围,3-4挡的换挡时间也正常,检查发现,尽管各个挡位的换挡时间都在行驶中变化,但变速箱的齿轮比始终是在1.0左右(0.98-1.02),没有变化。
