Auto Transmission Problem Diagnosis for Mercedes-Benz C220 1996

Removal and installation of transmission from vehicle chassis. Back for transmission repair time. Removal and installation is not included. Identification: identification code is stamped on the identification plate on the transmission housing. Identification code used parts when ordered. 4 or 5 fully automatic transmission – torque converter elements of a 3, 2 or 3 compound planetary gear sets, multiple 2 or 3 – clutch disc, clutch and brakes, overrunning one band 3 are welded speed involved. See fig. 1 and 2. Planetary gear set brake control function of the band. A hydraulic system, a primary gear type pump and a secondary piston pump type elements and provide friction to work automatically control pressure from the pressure of work was necessary. In reverse gear, reverse, brake B-3, apply a converter clutch, clutch is engaged and has stopped K -2. Both planetary gear sets include gear reduction. Location selector lever from the valve body receiving mode selector switch, accelerator (control pressure) conditions, intake manifold vacuum pedal, kickdown function (if activated) and vehicle speed. Primary and secondary pumps: the primary pump is located in front cover and torque converter transmission through the engine is driven. Primary pump as long as turning powered engine, and the entire hydraulic system pressurized oil supplies. Cut off by the secondary drive pump – piston is closed, through the primary pump pressure. Secondary pump: a secondary pump and tow rope – is necessary for starting the vehicle. Work pressure work circuit pressure control valves are basic pressure control valve, 2 examined two types of balls, a modulating pressure relief valve, one way valve and restrictor. Work pressure circuit accelerator pedal position, vehicle speed, the selector lever is in control of the situation and started gear. On some models geared for 2 to 3 upshift 60-80 seconds delay its catalytic converter capable of operating temperature is reached faster. Transmission troubleshooting. Modulating the wrong pressure. Transmission slips when out in 1 or 2 begins. Transmission slips during 2-3 Upshift or early slips. Hydraulic pressure test, Modulating pressure test.
