Shift Comments That T.V. Cable Adjustments Will Not Correct 1982-83 THM 700-R4
Control Valve Assembly
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. (Figure 1)
Before servicing any 1982 or 1983 THM 700 R-4 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:
