What should I pay attention to when automatic wave maintenance tells the gearbox of electromechanical failure? We only need to remove the transmission computer and solenoid valve for maintenance, so that we can learn more about this transmission in detail and faster. Our maintenance personnel have summarized some maintenance cases about this transmission. Now start to disassemble and repair the transmission computer.

取下放油螺絲，放掉變速箱內(nèi)油液，然后對(duì)變速箱油底殼進(jìn)行拆卸，對(duì)損壞點(diǎn)進(jìn)行檢查和維修。

Remove the oil drain screw, drain the oil in the transmission, then disassemble the transmission oil pan, inspect and repair the damaged points.

變速箱油底殼拿下，拿下油底殼時(shí)，要注意變速箱內(nèi)部是否還有殘留油液，確定油液放掉后，就可以拆卸電腦和閥體。

Remove the transmission oil pan. When removing the oil pan, pay attention to whether there is residual oil inside the transmission. After the oil is drained, you can remove the computer and valve body.

發(fā)現(xiàn)變速箱內(nèi)因磨損不能及時(shí)被濾網(wǎng)過(guò)濾掉的粉末性臟污，這也是變速箱機(jī)電單元為何會(huì)損壞的真 正原因，由于變速箱機(jī)電單元對(duì)變速箱內(nèi)部工作環(huán)境要求非常高，圖中的變速箱由于長(zhǎng)期得不到保養(yǎng)導(dǎo)致油的潤(rùn)滑度達(dá)不到標(biāo)準(zhǔn)，從而會(huì)加 快變速箱的磨損，和使用壽命的縮短。

It is found that the powdery dirt in the gearbox can not be filtered out by the filter screen in time due to wear, which is also the real reason why the electromechanical unit of the gearbox is damaged. Because the electromechanical unit of the gearbox has very high requirements for the internal working environment of the gearbox, the lubrication of the oil in the gearbox in the figure can not meet the standard due to long-term lack of maintenance, which will accelerate the wear of the gearbox, And shortening of service life.

拆下變速箱電腦和閥體，由于電磁閥不能正常工作，導(dǎo)致變速箱出現(xiàn)頓挫和鎖檔現(xiàn)象，經(jīng)過(guò)維修人員檢測(cè)發(fā)現(xiàn)故障，是由壓力控制電磁閥3卡滯造成。（在這里提醒大家，變速箱電腦故障，在損壞不嚴(yán)重的情況下，一般是可以修復(fù)的）。如果是電磁閥故障，必 須要更換新的電磁閥。還有閥體，閥體輕微的油污堵塞是可以通過(guò)清洗來(lái)修復(fù)，而磨損的閥體就不能在修復(fù)，只能更換新的閥體才可以解決問(wèn)題。

The computer and valve body of the transmission were removed. The solenoid valve could not work normally, resulting in the collapse and gear locking of the transmission. The maintenance personnel found that the fault was caused by the sticking of pressure control solenoid valve 3（ I would like to remind you that the failure of the transmission computer can generally be repaired if the damage is not serious). If the solenoid valve is faulty, it must be replaced with a new solenoid valve. There is also the valve body. The slight oil blockage of the valve body can be repaired by cleaning, while the worn valve body can not be repaired. The problem can only be solved by replacing the new valve body.

把已經(jīng)損壞的電磁閥進(jìn)行更換，故障解除，由此可見(jiàn)變速箱出現(xiàn)故障，及時(shí)檢查及維修，才不會(huì)避免其他內(nèi)部?jī)杉p壞帶來(lái)的損失。

Replace the damaged solenoid valve and remove the fault. It can be seen that the gearbox has a fault. Check and repair it in time, so as not to avoid the loss caused by the damage of the other two internal parts.
