Peugeot car automatic transmission troubleshooting instances

Fault symptom: automatic transmission slipping, under the car. This car in running of the first automatic transmission slip, and then the car under the smoke, then cannot travel. Troubleshooting: First survey of automatic transmission oil cooler oil level, when the liquid level higher than the maximum around 1.5cm, the oil is dirty, a transmission oil burning after the characteristic odor. Further test operation, heating and automatic transmission oil, so that the observed after heating automatic transmission oil can rise to the level of what. Test operation of Italian (Forum Gallery) found outside the upshift is quite smooth, from1rise to 2gear, from2rise to 3files, can be the normal shift, but entered the4 gear, the acceleration of the engine, automatic transmission will start to slip. Put the gear selector lever is placed on the 3position, the3gear to return to a normal state. R stalls are normal. Do stall test, either forward or backward, the engine stall speed is2100r/min, is normal. Raise are the vehicle up to slip ring investigate, in an automatic transmission and engine between the area, the subframe and the power steering pump leakage of many in the area of automatic transmission oil. Smoking cause, perhaps is the automatic transmission oil leak onto the exhaust pipe. Steam cleaning, in order to confirm the oil spill, lifting up his car, put the gear selection lever in the D position, to run continuously for 20minutes, not found in automatic transmission oil. Remove automatic transmission oil pan at the oil pan, there is too much grinding powder clutch. This forced decomposition of automatic transmission. The automatic transmission from the car downs, then the decomposition operations. First remove the E clutch, the brake drum parts have been heat discoloration, friction plate grinding burn, steel exposed. Because of the heat, the piston seal hardening. The rest of the A, B, C, C ', D each clutch, internal are not particularly unusual. This4 gear slip causes have been clarified, but why the E clutch is not good? Put all the parts disassemble cleaning. The valve body is electronically controlled, but the three stacking of a very complex body. But the body, operating smoothly, but also found no other abnormalities. All the valve core movement smoothness,10throttle position, the aperture and the installation directions and information in line with the normal, spring. Cover almost by ordinary tools can decompose. But the fixed roller bearing outer ring nut, must use special tool removal. The nut is used to produce their own tools to ring slip remove. Without the use of special tools, and the use of universal joint wrench, screwdriver and hammer head can be removed, but the nut to be injured. While the installation must be used 5ON m torque into tight. So there must be special tools. Manufacture of special tools can use abandoned roller bearing outer ring, wheel and small grinding machine processing into one clutch shape, and then take a socket interface of the driving rod is cut by half, and then welding welding it. The nut, and in diameter, thinner thickness, tightness of the nut, stressing points in its radius extension line. Go back to slip rings the starting point, along the E clutch pressure oil supply channel under investigation. Results show that pressure oil is pumped from the interior of the hood of the hole. Through the turbine shaft hole and enter the E clutch piston side. Turbine shaft hole and the embedded with a steel ring, a seal, as if the engine piston ring. The steel ring to moderate degree of tightness and the pump casing inside diameter contact, the inner diameter of the pump of this part of pressing a bronze sleeve. Steel ring and the inner sleeve contact portions are in a circular wear. Hands touch, obviously wear a stage, forming a groove, which is probably the E clutch wear.
