To help eliminate complaints of automatic transmission fluid (ATF) leakage, improved transmission oil pans and gaskets have been introduced into
production as a running change on 1989 900 models. They may also be used as a service fix. The pan and gasket improvements consist of:
^
Modified front and rear oil pans.
^
Improved gaskets made of a new material containing a thin, sheet-metal lamination for reinforcement.
^
Two-piece reinforcing frames for each pan.
^
Longer screws with integral washers.
The improved pans and gaskets were introduced as a pilot series from transmission numbers 013-6514 to 013-6613. They were introduced into regular
production beginning with transmission numbers 013-6950 and 014-5129.
Kits are available for both the front and rear pans to correct leakage complaints on transmissions before the gearbox serial numbers listed above. Earlier
style oil pans have been superseded by the kits containing the new components.
NOTE
In the cases where the oil pans are being replaced to correct oil leakage, both the front and rear transmission oil pans should be replaced at the same time
to prevent future leakage.
Along with the introduction of these new pans and gaskets, the recommendation for retorquing the pan screws at the 1000-mile service has been dropped.
This also applies for cars that have these pans installed as a service fix. Retorquing of the securing screws should not be done because it can disturb the
"set" of the gasket and result in ATF leakage.
To provide additional clearance between the new-style oil pans and the skidplate, a modified skidplate (P/N 40 07 449) with four dimples stamped into
the front edge has been introduced into production starting with VIN's AJ7052666, AK3006038, AK7006870. Early style skidplates can be installed with
spacer washers to provide adequate clearance. See page 3 of this S.I. for details.
