判斷變速箱工作狀態好壞，直觀的就是換擋速度和換擋時的質感。簡單來說，就是老爺們打算超車加速時，變速箱會不會及時降檔；需要巡航時變速箱會不會平順，快速地升到高檔位進行巡航。
The intuitive way to judge the working status of the gearbox is the shifting speed and the quality during shifting. Simply put, when the old man plans to overtake and accelerate, will the gearbox downshift in a timely manner; When cruising is required, will the transmission smoothly and quickly shift to high gear for cruising.
變速箱不僅降檔反應巨慢，2檔升3檔還有明顯的頓挫和瞬間失速，這種情況完全不是一個正常老化的情況。順便把
濟南變速箱油也一并換掉：
The gearbox not only has a slow downshift response, but there are also obvious jerks and momentary stalls when shifting from second to third, which is not a normal aging situation at all. By the way, change the Jinan transmission oil as well:
油底殼拆下來，用原始的重力換油法來檢查整個變速箱。特地接了一小杯整個變速箱油。
Remove the oil pan and use the original gravity oil change method to inspect the entire transmission. Specially received a small cup of the entire transmission oil.
老油發黑粘度下降嚴重，聞起來還有一絲焦糊味。
The old oil blackens and the viscosity drops severely, with a slight burnt smell.
既然是傳統的重力換油法，接下來就是拆油底殼清洗和更換集濾器，基本上變速箱臟的一面都可以展現在眼前。變速箱閥體的集濾器基本已經被研磨下來的金屬粉末覆蓋成了黑色，油底殼一樣也是厚厚的一層油泥和金屬粉末混合物。
Since it is a traditional gravity oil change method, the next step is to remove the oil pan for cleaning and replace the filter. Basically, the dirty side of the gearbox can be displayed in front of us. The filter of the gearbox valve body has been basically covered in black with ground metal powder, and the oil pan is also a thick layer of oil mud and metal powder mixture.
油泥和金屬粉已經完全蓋掉了原本的油底殼顏色
The oil sludge and metal powder have completely covered the original oil pan color
磁鐵也是滿滿的金屬粉末
Magnets are also filled with metal powder
原本銀白色的集濾器濾芯也變成了金屬灰色
The originally silver white filter element of the collector has also changed to metallic gray
檢查完后就是簡單地清洗和更換維修包配件，先用化清將油底殼和整個變速箱閥體沖洗干凈，擦干后安裝新的閥體集濾器，安裝上新油底殼密封膠條就可以進行換油作業了。
After inspection, simply clean and replace the repair kit accessories. First, rinse the oil pan and the entire transmission valve body with a chemical cleaning agent, wipe them dry, and then install a new valve body filter. Install a new oil pan sealant strip to proceed with the oil change operation.
新的閥體集濾器濾芯用新變速箱油涂抹后安裝，主要就是6個步驟：
The installation of the new valve body filter element is mainly carried out in six steps after applying new transmission oil:
(1).向加油口內加入變速箱油，直到油位孔開始均勻出油，停止加油，擰上油位孔螺栓。
(1) Add transmission oil to the oil filler until the oil level hole starts to evenly discharge, stop refueling, and screw on the oil level hole bolt.
(2).啟動發動機，怠速30秒，從倒擋開始依次換擋，每個檔位保持30秒，熄火，靜止2分鐘。
(2) Start the engine, idle for 30 seconds, shift gears sequentially from reverse gear, hold each gear for 30 seconds, turn off the engine, and remain stationary for 2 minutes.
(3).打開油位孔和加油孔，繼續加油，直至油位孔開始均勻出油。
(3) Open the oil level hole and refueling hole, and continue to refuel until the oil level hole begins to evenly discharge oil.
(4).重復步驟(1)-(3)兩遍。
(4) Repeat steps (1) - (3) twice.
(5).擰好加油螺栓，油位孔螺栓。
(5) Tighten the refueling bolts and oil level hole bolts.
(6).完成加油上路，測試每個檔位都保持10秒鐘后回到店內再次檢查油量。
(6) After refueling and driving, test each gear for 10 seconds before returning to the store to recheck the fuel level.
After changing the oil, the 2-3 gear, which had previously experienced severe jerks, became very smooth. It's not an exaggeration to say that without looking at the gear icon on the instrument panel, I don't know if I have already shifted gears.
