727 Transmission Throttle Linkage Adjustment

Contributed By: Tom Collins

In the Jeep Factory '84/85 GW & truck manual M.R.253 for the 727 & V8 engine. Here's what follows:


The throttle linkage adjustment is important to proper operation. This adjustment positions a valve which controls the shift speed, shift quality and part of the throttle down shift sensitivity. If the setting is too short, early shifts and slippage may occur. If the linkage setting is too long, shifts may be delayed and part throttle down shifts may be very sensitive.

This adjustment is so important that the use of a throttle lever holding spring is necessary to remove slack in the linkage during adjustment. Refer to THROTTLE LINKAGE ADJUSTMENT...

  1. Disconnect the throttle control rod spring(1) at the carburetor.
  2. Raise the vehicle
  3. Use the throttle control rod spring to hold the transmission throttle valve control lever forward against the stop.
  4. Block the choke open and set the carburetor throttle off the fast idle cam.
  5. NOTE: On carburetors equipped with a throttle operated solenoid valve, turn the ignition lock to the ON position to energize the solenoid. Then open the throttle halfway to allow the solenoid to lock and return the carburetor to the idle position.

  7. Push on the end of the link retaining bolt.
  8. Install the nylon washer(4) and spring clip(5).
  9. Remove the throttle control rod spring(1) from the linkage and install it on the rod.
