  1. Disconnect the oil cooler pipes at the transmission. Plug the openings to prevent system contamination or excessive fluid loss.
  2.  
  3. Disconnect the TV cable at the transmission.
  4.  
  5. Remove the transmission-to-engine mounting bolts and fasten the torque converter to the transmission using a converter restraining tool or a length of wire.
  6.  
  7. Carefully move the transmission rearward, downward and out from under the vehicle. If interference is encountered with cables, cooler lines, etc., remove the component(s) before finally lowering the transmission.
  8.  

To install:
  1. Flush the transmission oil cooler lines using J-35944 or an equivalent transmission cooler and line flushing tool.
  2.  
  3. Install a converter restraint tool to hold the torque converter in place.
  4.  
  5. Support the transmission with a suitable jack, then raise the transmission into position and remove the torque converter holding tool.
  6.  
  7. Install and tighten the transmission to engine bolts to 35 ft. lbs. (47 Nm).
  8.  
  9. Connect the TV cable to the transmission.
  10.  
  11. Remove the plugs, then connect the oil cooler pipes to the transmission.
  12.  
  13. Align the marks made during removal and start the torque converter to flywheel bolts by hand. Tighten the bolts to 46 ft. lbs. (62 Nm).
  14.  
  15. Install converter cover and tighten screws to 89 inch lbs. (10 Nm).
  16.  
  17. Engage the electrical connectors to the transmission.
  18.  
  19. Connect the shift control cable.
  20.  
  21. Engage the speedometer electrical connector.
  22.  
  23. Align the marks made earlier and install the driveshaft, then the driveline support beam.
  24.  
  25. Install the exhaust system, if equipped, the underbody braces.
  26.  
  27. Lower the vehicle and install the oil level indicator.
  28.  
  29. Connect the TV cable to the throttle lever or to the adjuster assembly.
  30.  
  31. Connect the negative battery cable.
  32.  
  33. Check and add the proper type and amount of transmission fluid.
  34.  
  35. Because the driveline support beam was removed, check clearance between the air intake duct and the throttle body. If the air duct becomes dislodged from the throttle body, a driveability problem could occur.

Fig. Fig. 6: Throttle Valve (TV) cable adjustment procedure-1984-91 vehicles

1992-96 vehicles

Beginning in 1992, the Acceleration Slip Regulation (ASR) system was added to all Corvettes. This required a cable adjuster assembly which has the ability to extend cables slightly, according to commands from the control module. This extension allows the throttle close regardless of accelerator pedal position. The adjuster does not have the ability to apply throttle, it can only release it.

The cable adjuster assembly must be adjusted each time the throttle and/or TV cables are disconnect. On some models, the TV cable is also attached to a servo. The cable may be adjusted BEFORE cable adjuster assembly adjustment.

  1. Make sure the TV cable is installed into servo bracket.
  2.  
  3. Pull servo assembly end of cable toward servo without moving the throttle lever.
  4.  
  5. If 1 out of the 5 holes in the servo assembly tab aligns with the cable pin, push pin through hole and connect pin to tab with retainer.
  6.  
  7. If the tab holes does not align with the pin, move the cable away from the servo assembly until the next closest tab hole aligns and connect the pin to the tab with the retainer.
