General Repair Information

To ensure perfect and successful transmission repairs, the greatest care and cleanliness as well as the use of good and proper tools is essential. The usual basic safety precautions also apply when carrying out vehicle repairs.

A number of generally applicable instructions for individual repair procedures, which are otherwise mentioned at various points in the Repair Information, are summarized here. It applies to this repair information.

Transmission

• Observe rules of cleanliness for working on the transmission => [ Clean Working Conditions ] Clean Working Conditions.

• Clean ATF lines and ATF cooler after performing repairs on the transmission.

• Reusable components must be cleaned, checked and reconditioned if necessary before installation.

After installing, following fluid levels must be checked and topped off if necessary:

• ATF level => Automatic Transmission/Transaxle Automatic Transmission/Transaxle

• Gear oil in front final drive => Transmission and Drivetrain Transmission and Drivetrain

• Capacities and specifications Automatic Transmission/Transaxle

O-rings, gaskets, seals

• O-rings, gaskets and seals must be replaced.

• After removing gaskets and seals, always inspect the contact surfaces at housing or shaft for burrs resulting from removal, or for other signs of damage.

• The open side of the gaskets points toward the fluid to be sealed in.

• To install, thinly coat gaskets along outer circumference and on sealing lip with ATF.

• Coat O-rings with transmission fluid or Vaseline before inserting to prevent crushing rings during installation.

• Use only ATF or Vaseline in areas near ATF. Other lubricating substances cause functional problems in the hydraulic transmission control.

• When pressing in new gaskets, make sure the sealing lip does not run on the same point as the sealing lip of the old seal (use insertion depth tolerances).

• Replace paper seals, always clean sealing surfaces and remove old seals completely.

Bolts and Nuts

• Loosen bolts in reverse order of tightening.

• Tighten and loosen bolts or nuts for securing covers and housings without tightening sequence in diagonal sequence in stages.

• The tightening specifications stated apply to non-oiled nuts and bolts.

• Replace self-locking bolts and nuts.

Fasteners





• Do not over-stretch circlips.

• Always replace damaged or over-stretched circlips.

• Circlips must locate properly in the groove.

• Replace spring pins. Installation position: Slot is longitudinal to line of force.

Mount

• Slightly grease mount with ATF before inserting.

• Attach mount and adjustment shims only with Vaseline. Other lubricating substances lead to functional problems in the hydraulic transmission control.
