NEW OIL PRESSURE PLUG USAGE THM 700-R4 SERVICE

Beginning October 12, 1982, all THM 700-R4 transmissions were built with a new oil pressure plug in three (3) locations (see Figure 1).

The past oil pressure plug will still be used at the line pressure tap location. The new oil pressure plug will be used at the 2nd clutch, 3rd clutch and 4th clutch pressure tap locations (see Figure 1).

To install these oil pressure plugs, apply thread sealant on the plug and torque as follows:

Torque past oil pressure plug to 11 N.m (8 ft. lbs.). Torque new oil pressure plug to 24 N.m (18 ft. lbs.).

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
