A/T - Shift Comments T.V. Cable Adjusting Won't Correct

Number 83-I-146 Section 7 Date 09/83
Subject: SHIFT COMMENTS THAT T.V. CABLE ADJUSTMENTS WILL NOT CORRECT - 1982 AND 1983 THM 700-R4



Some 1982 and 1983 THM 700-R4 transmissions may exhibit erratic shift conditions that adjusting the T.V. cable will not correct. The erratic shift condition may result from a sticking throttle valve. Check for a nick on the throttle valve sleeve, in the area of the coiled spring locating pin (see illustration)..
Before servicing any 1982 and 1983 THM 700-R4 transmission for this erratic shift condition, three preliminary checks should be made first. Check the transmission oil level, T.V. cable adjustment, and oil pressures. Refer to your Service Manual for proper specifications. If these checks are correct, refer to the repair procedure below:



REPAIR PROCEDURE

1. Remove the throttle valve train from the control valve assembly (refer to illustration).

2. Inspect the throttle valve and throttle valve sleeve for nicks or burrs. Remove nicks or burrs with crocus clotch.

3.. Insert the throttle valve into the throttle valve
sleeve and inspect for freeness of the valve in the sleeve.

4. Reassemble the throttle valve train into the control valve assembly.
