Setting the T.V. Cable on 4L60/TH700 Automatic Transmission

Setting Conditions

  • Test drive first and note shifting speeds and kickdown speeds.
  • Car parked with engine NOT running transmission in park.
  • Make sure when Throttle pedal is at Full Throttle the Throttle body also has 100% Throttle.

Setting Procedure

  • Release the cable lock and pull the cable away from the throttle body until its stops then allow it to lock.
  • Now open up the throttle body to full throttle either by hand or using the throttle pedal this cant be done to fast it may over adjust.
  • This is now set to the MAXIMUM T.V Setting you can mark with white out for a point of reference.
  • Test Drive the Vehicle and note the shifting speeds and kickdown speeds.
  • You may need to allow for 1 click towards the throttle body.

Test Drive Procedure

  • Make a light Throttle 1-2 upshift then full throttle to preform a 2-1 down shift. This can be preformed as soon as the transmission shifts into 2nd gear.
  • Next at a legal speed area or 60kmh in 3rd (Can have it selected with shifter) full throttle to preform a 2-3 down shift.
  • These shifts should be achievable at either 1 click or Maximum T.V. adjustment.

No Success?

  • The T.V. valve in the valve body is prone to sticking as well as the governor you could try a transmission treatment if caught early enough. The T.V. valve can be worked while driving but if it sticks again in a short period of time its need to be repaired. When the sump is removed and there are no signs of transmission debris on magnet or bottom of sump a good valve body clean will fix the issue. If the sump is full of metal and material it will only stick againuntil the internal problem is fixed.
