Throttle Valve / Kickdown Cable - A442F - 35520-60060

Kickdown / Throttle Valve Cable for Land Cruiser 70 & 80 Series

Cable replacement procedures are at the bottom of this product description.

This kickdown cable suits Land Cruiser 70 Series Heavy duty models using the A440F, A442F transmissions in combination with the 1HZ engine.

It also suits LHD and RHD Land Cruisers in the 80 Series lineup using the 1HZ, 1HDT and 1HDFT engines.

The most common reason to replace this cable is that it starts to bind due to wear or fraying of the cable or rusting of the cable from water entering the cable housing, leading to increased transmission pressures when the cable sticks in a partially pulled out condition. Increased pressures in the earlier hydraulic transmissions will cause hard, late shifting, and often holding a gear for too long before shifting (the late shift, or no shift).

In the electronic transmissions, the shifts are electronically controlled by the ECU and shift solenoids, however the TV cable still affects transmission pressure and will cause hard shifts (transmission clutches engage more abruptly).

This model list may not be complete. If in doubt, check the part number vs what is listed here.

• The overall length of the cable housing with the orange tip removed is 115cm.
• The overall length of the cable itself is 133 cm from the ends of the beads.
• The threaded portion at the injection pump ends is 33mm long and is an M8 thread.

To replace this cable, the transmission oil pan needs to be drained and then removed. The pan does not use a gasket, so you'll need some Form in Place Gasket maker to reseal it. You'll also need about about 8L of ATF and a transmission fluid funnel (has a skinny tube that can go into the dipstick hole), and some dry solvent such as brake cleaner to complete this job.

The basic procedure is as follows - double check this with the FSM if you are in doubt:
1. Remove the transmission fluid dipstick.
2. Remove the transmission protection (aka skid) plate. Drain the fluid from the transmission pan (24mm) and remove the bolts holding the pan (10mm).
3. Break the seal on the oil pan with a pan remover tool - this can be challenging - and lower it a few cm on an angle - more ATF will drain out of the valve body once air gets in (hint: don't be in a rush to take the pan away or you may end up bathing in ATF).
4. Drain the pan again to get the rest of the fluid out.
5. Clean the gasket surfaces and dry the metal surfaces with a dry solvent such as brake cleaner.
6. Remove the kickdown cable from the injection pump throttle linkage (14mm)
7. DO NOT REMOVE THE VALVE BODY - yes, it says to do this in the FSM, but it's not needed.
8. On the right front part of the underside you can see the cable entering the transmission. Use some tool to rotate the cam that the kickdown cable attaches to so you can get at the bead end and remove it from the cam. 
9. Use a side cutters and cut the cable end off.
10. Use a dull tool like a long 1/4" socket extension to push (or gently hammer) the plastic cable end up and out of the transmission. Don't damage the transmission, only push against the plastic end of the cable housing that protrudes into the transmission. Some plastic bits may break off the cable end - don't leave these in the transmission.
11. Cut the plastic end off the cable so you're only left with the housing tube.
12. The cable is secured to the top of the transmission by a bolted down clamp.... there's no easy way to get this off and thread the new cable through it when the transmission is still in the vehicle.
13. Go up to the engine bay and feed the new cable down to the transmission approximating the route the original cable followed.
14. Grab the old cable housing with some strong pliers or vice grips and start yanking it up and out. It's going to take some force to do as the cable clamp does not want to let go. A few strong jerks will often get it out. You can also leave it in place... just tie it out of the way.
15. Go back down the transmission and carefully (no dirt in the transmission!) feed the cable and housing through the hole the old cable came out of. The o-ring that seals the cable to the housing should be lightly oiled with ATF to help it go into place before pushing the cable end into the transmission. The cable end should clip into place and not come back out when tugged gently. 
16. Rotate the cam around to feed the bead end of the cable into its hole, and route the cable over top of the cam.
17. Back up to the engine bay again, and clip the cable housing into the metal cable clip/holder that's just just above the starter.
18. Next, attach the cable to the cable holder at the throttle linkage.
19. Gently pull the cable through and check that it moves in and out smoothly under the spring tension of the cable cam in the transmission. Check that the cable is properly following the cam in the transmission.
20. Apply a thin bead of sealant around the cleaned oil pan and replace the oil pan. Don't over tighten the small bolts. Put the skid plate back. Check that the drain plug is tight.
21. Gently pull the the cable until you feel no slack - this is where the supplied bead gets crimped into place - about 2mm forward of the orange rubber boot. Gently crimp the bead into place.
22. Fill the transmission with high quality ATF (I strongly advise synthetic fluid). It will take around 6.5 to 7.5 Litres. Don't over-fill and don't under-fill. The engine needs to be running with the trans in Park to get a good reading of the oil level. Sometimes shifting through the gears to get the fluid moving through the transmission provides a more accurate reading - do this with the brake pedal applied.
23. Double check all of your work, and make sure there are no leaks. Adjust the cable as per the FSM.

The kickdown cable should have no slack in it, and it should start moving as the throttle lever arm on the injection pump moves.

A tighter cable will cause firm shifts that are slightly late (holds on to the gears a little longer before shifting, revs a bit more before the next shift) and a slack cable causes earlier and softer shifts. There's a happy medium - soft shifts cause increased wear on the clutches in the transmission (avoid this!), but overly firm shifts can be annoying. If in doubt, get help from someone with some real experience and expertise, not just internet/armchair expertise.
