Repair informationScrupulous care and cleanliness, as well as proper tools are essential requirements for carrying out perfect and successful gearbox repairs. The generally valid basic rules of safety naturally also apply to repair work. A number of generally valid notes for individual repair operations - which are otherwise listed at several points in the workshop manual - are summarised here. They apply to this workshop manual. Gearbox Do not run engine when the oil sump has been removed or without ATF in the engine and do not tow vehicle. When replacing the automatic gearbox, inspect the ATF in the planetary gear page37-22 and the ATF in the final drive page 39-1, and top up if necessary. Capacities and specification page 00-4. When the gearbox is removed, protect the torque converter from dropping out. Thoroughly clean connection points and the surrounding area before disconnecting. Before installing the gearbox, check the install dimension of the torque converter page 32-3. When installing gearbox, ensure the dowel sleeves are correctly located. Place removed parts down on a clean surface and cover over. Use sheeting or paper. Do not use fluffing cloth! Carefully cover over or seal opened components if repairs are not carried out immediately. Install only clean parts: Do not remove replacement parts from their wrapping until just before installing. Rules for cleanliness when carrying out work on automatic gearbox page 37-28. O-rings, seals, gaskets Always replace O-rings, seals and gaskets.

After removing gaskets, inspect the contact surface on the housing or shaft for burrs or damage related to removal operations. Coat the outer circumference and the sealing lip of seals with ATF for installing. Coat O-rings with ATF for inserting in order to avoid the rings being squashed when installed. On no account use any other lubricants in the ATF area otherwise there is a risk of operational problems with the hydraulic gearbox control. The open side of the seals points toward the fluid to be sealed. After installing, inspect ATF level in the final drive and planetary gear and adjust to correct level, if necessary. Locking elements Do not over-tension circlips, replace if necessary. Circlips must be resting properly in the base of the groove. Nuts, bolts Slacken the bolts in the opposite direction of the tightening sequence. Slacken and tighten nuts or bolts for attaching covers and housings diagonally in stages, if no tightening sequence is stated. Replace self-locking nuts.

Technical Data Bearings Position needle bearings with the inscribed side (larger sheet thickness) toward the insertion drift. Insert bearings in gearbox with ATF. Carefully oil taper roller bearings in gearbox for friction torque measurements, particularly up to gearbox date of construction 26.4.1998. Do not insert taper roller bearings in gearbox with ATF from gearbox date of construction 27.4.1998. Do not mix up the outer and inner races of equally large bearings. Always replace all the taper roller bearings fitted to a shaft, and use makes of one manufacturer. Shims Re-gauge shims with a micrometer at several points. Different tolerances make it possible to exactly gauge the required shim thickness. Inspect for swarf or damage. Install only shims which are in proper condition. Internally-toothed discs Place new internally-toothed discs in ATF for 15 minutes before installing. Control valve body If the shift elements are scorched, the control valve body should be replaced. Clutches Clutches K1, K2 and K3 should be disassembled only for cleaning; if individual parts are faulty, replace clutch. The clutches are assigned by means of the gearbox code letters. Self-diagnosis Before carrying out service work on the automatic gearbox, determine the cause of the problem as accurately as possible with the aid of Repair Group 01 Self-Diagnosis page 01-1.

Self-Diagnosis/Electrical Test

Self-diagnosisFunction of self-diagnosis The control of the automatic gearbox is performed electronically/hydraulically. The term self-diagnosis relates to this electrical/electronic control. Control unit -J217- with driving situation shifts (fuzzy logic) The determination of the gearbox shift point in line with the driving situation and resistance is carried out automatically. Advantages: l Gearshifts are conducted to achieve good fuel economy l Maximum engine power is always available l Individual adaptation of shift points to all driving situations l Shift points can be altered as desired Variation of shift points on uphill or downhill sections When driving on uphill or downhill sections, the gearshifts are selected automatically by additional shift maps as a function of accelerator pedal position and vehicle speed. l Shift map for driving on extreme uphill sections is matched to engine power l Shift map for driving on extreme downhill sections is matched to the braking effect of the engine Functions of the gearbox control unit The automatic gearbox control unit -J217- receives information from components which affect the gearshifts and passes on this information to the solenoid valves with which the control valves in the control valve housing are operated. To enable the cause of a failure of an electrical/ electronic component or an open circuit in the wiring to be determined as rapidly as possible, the control unit is equipped with a fault memory. Faults are detected by electrical signals and stored in the fault memory.

Self-Diagnosis/Electrical Test

Electrical faults which may affect vehicle handling, can be determined with the vehicle system testers V.A.G 1552, V.A.G 1551 or VAS 5051. Notes: The description which follows relates to the vehicle system tester V.A.G 1552 using the programme card 5.0 or a higher version.

Use of the vehicle system testers VAS 5051 and V.A.G 1551 with integrated printer is similar. Minor differences are possible in the readouts in the display. List of available functions page 01-6. Backup functions of gearbox control unit If critical faults occur when driving, the gearbox continues operating in the emergency mode and it is possible to continue driving the vehicle. If the fault occurs in D, 3, or 2, the emergency mode then activates 3rd gear. If the fault occurs in 1, P, N or R, the emergency mode activates the gear in question. If the engine is re-started in the emergency mode and the fault occurs (when selector lever is in position D, 3 or 2), 3rd gear is activated hydraulically until the fault is rectified. In the case of faults which result in the emergency mode being activated, the gearbox continues to operate in the emergency mode until the fault is no longer detected by the control unit over a certain period. Faults which may activate the emergency mode: Open circuit in wiring, short circuit, faulty electrical or hydraulic components. Recognition of faults by gearbox control unit If a fault exists, the fault is stored as a static (present) fault. If the fault no longer exists for a certain period or distance, the fault is converted to a sporadic fault. Faults which are stored in the fault memory as occurring sporadically, are displayed as Sporadically occurring fault when interrogating the fault memory. In this case SP also appears in the right of the display.

The solenoid valves can be tested when driving in measured value block 08, display group number 004.

The solenoid valves actuated -N88, -N89 and -N90 are stated in the table in the individual selector lever positions. These solenoid valves control the shift valves for the corresponding gears. Solenoid valve -N91 controls the shift valve of the torque converter lock-up clutch.

The readout on V.A.G 1552 in display block 1 is 6-digit (0000 00).
