If you encounter vehicles which were produced before the modifica
Ä
tion and have the problem mentioned above, replace the gear oil
with SAE75W-90.
NOTE: Do not mix engine oil or ATF into transmission gear oil. Also,
do not use it instead of manual transmission gear oil since it
may result in scoring of the gears and premature wear of shift
rods.
