NEW GOVERNOR SCREEN ADDED TO CASE

Models  1989 6000, BONNEVILLE AND GRAND PRIX EQUIPPED
Affected:

WITH THM 440-T4/HYDRA-MATIC 4T60, F-7 (ME9)

BULLETIN COVERS:

A new Governor Screen (3) was added to the Governor Shaft Sleeve in the Case. The Governor Screen will minimize the potential of sediment entering
the Governor Assembly and preventing the Governor Balls from seating properly.

FIGURE 2 - NEW GOVERNOR SCREEN

SERVICE ACTION:

(Figure 2)

A machining change in the Case to provide clearance for the Screen will not permit installation of the Screen in past model Cases.

Important:

Do not attempt to drill previous design Cases in order to install a Governor Screen due to critical dimensions.
