Date: Apr., 1983
Subject: EXCESS SHIFT EFFORT (GEAR RANGE SELECTOR) - 1982-83 PASSENGER CARS AND TRUCKS WITH THM 700-R4
TO: ALL CHEVROLET DEALERS


Beginning early January, 1983, all THM 700-R4 transmissions, except those used in "D" trucks, were built with a revised manual detent spring assembly. This revision will reduce the amount of effort required to operate the transmission gear range selector.

To correct a customer comment of excessive range selector shift effort on a THM 700-R4 transmission built prior to January, 1983, replace the manual detent spring assembly. Use the following chart to determine the correct part number.
