ATTENTION: This bulletin replaces bulletin Group 3, Number 8702, dated December 11, 1987.
When repairing 911 Turbo transmissions for hard shifting of 1st and 2nd gears, the reverse gear operating fork should be checked for damage or distortion.
FIGURE 1:
The fork should be replaced if it is bent or not symmetrical. See figure 1.
An asymmetrical or bent fork can put pressure on the detent between the reverse gear shift rod and the 1st and 2nd gear shift rod resulting in 1st and 2nd gear hard shifting.
The reverse gear operating fork material thickness was increased from 3.5 to 4.5 mm.
From Production Date: October 9, 1987.

New Part Numbers
Operating fork: 930 303 019 01

When replacing the operating fork on transmissions prior to the above transmission numbers pivot pin must also be replaced.
It might be necessary to remove material from the inside of the front transmission cover in the area of the reverse gear fork to obtain sufficient clearance.
Shift transmission into reverse several times before installing in vehicle to ensure reverse gear fork does not contact the housing.
