5 Speed Transmission fluid change procedure

Frequently asked questions
  • A) Notes.
  • 1) If the oil pan contains a lot of metal shavings, then the transmission might already have an internal damage. An oil change will not fix a mechanical transmission problem.
    2) Drain and filler plug torque specifications vary by transmission type. Find the appropriate fluid level checking procedures for the transmission application you are working on.
    3) Check the ZF lubrication list TEML 11 for the correct transmission fluid to be used. Use of incorrect fluid can cause erratic transmission operation leading to complete transmission failure.
  • B) Fluid change procedure:
  • 1) Drive the vehicle so the transmission is at normal operating temperature.
    2) Drain the fluid by removing the drain plug (see the appropriate fluid level procedures chart for location)
    3) After the stream of fluid from the drain plug has reduced to a trickle, loosen and remove the oil pan screws leaving only the corner screws in place.
    4) To remove the pan, push and hold it against the transmission housing and remove the remaining screws.
    5) Remove any gasket material stuck to the transmission housing or the pan. Avoid scratching the sealing surfaces while removing the old gasket material.
    6) Remove the old oil filter. Filters vary by application and are held in place with two or three bolts, make sure to save the bolts for reuse.
    7) Place the o.ring onto the new filter were applicable, some filters use a ribbed type seal ring that is already installed. Lubricate the o.ring or ribbed seal with transmission fluid.
    8) Install the filter, gently push the filter neck into place without unseating or damaging the oring or ribbed seal.
    9) Install the filter bolts by hand while holding the filter in place, then torque to 5NM.
    10) Clean the pan thoroughly, use solvent and wipe or air blow dry, not to leave any residue.
    11) Position the oil pan gasket and install the pan. Place and hand tighten the corner screws first to hold the pan and gasket in place.
    12) Install all pan screws and torque to 10NM following a crisscross pattern.
    13) Install a new drain plug or drain plug seal and torque to proper specification. (see the appropriate fluid level procedures chart for torque value)
    14) Wipe pan and transmission housing not to leave any oil residue.
    15) Follow the appropriate fluid level procedure instruction.
