Ninety-Eight FWD V6-181 3.0L (1985)
1985-1/2 - 1986 Cutlass Ciera/Cruiser, Cutlass Supreme, Eighty Eight, Ninety Eight, And Toronado/Trofeo
A 3-2 shift maneuver is obtained by allowing the vehicle to coast down to 17-20 mph (with closed or zero throttle) and then stepping into the throttle to
obtain a 3-2 shift.
At start of production (SOP) 1987, an orifice pipe was added between the 1-2 servo release cover plate and the 3-2 coast down valve to allow a smoother
second gear apply (Figure 5). The four new parts installed as a set will service certain past model transaxles with a harsh 3-2 shift maneuver condition.
If the new pump body assembly has a "one terminal" 3rd clutch switch, remove it and replace with the "two terminal" 3rd clutch switch from the original
pump body assembly.
When servicing a transaxle for the above described condition in designated high altitude areas , also install the 3-2 control valve spring package
described in Section II of this bulletin.
Also ensure the 3-2 control valve and 1-2 servo control valve move freely in their bores.
Harsh 3-2 Coastdown Bump 3.8L or 4.5L At 15-22 MPH:
1985-87 Cutlass Ciera/Cruiser, Eighty Eight, Ninety Eight, And Toronado/Trofeo, With Transaxles Built Prior To December 18, 1986 (Julian Date 352)
And 3.8L Engines
A coastdown bump is obtained by allowing the vehicle to coastdown to 15-22 mph (with closed or zero throttle) and a sudden and forceful apply of the
1-2 band is first when the transaxle shifts from third to second gear.
