    Default 2.4gd6 hilux manual problems

    Hello i have a 2.4gd6 4x4 hilux 6 speed manual with 85 000km.

    Gearbox shifts badly to 2nd and alright to 3rd. So i had the car now at a gearbox place . The checked the synchros, bled the clutch , (had toyota previously check the gearbox linkages). While they were there i told them to replace the 2nd and 3rd synchro even though the old set looked 100percent. Long story short gearbox feels exactly the same after the new synchros.

    So my guess is the clutch , the workshop said the clutch has about 50% life left. If i remember correctly the car felt easier to shift into gear when i was driving on farm roads than it was on tar , earlier this year. Little tire slippage helps with shifting

    What do you guys think ?

    Just seeing what has been eliminated so far.

    Then your guess could be correct. Although it is strange that it's only one gear.

    Just a summary:

    Toyota checked the linkages.
    Gearbox workshop replaced 2nd and 3rd synchro even though they looked 100 percent , they also said gearbox looks very good inside.
    Gearbox workshop bled the clutch system.
    Have been through 3 different oils , still same issue.

    Is the sticky shifting the same when hot and cold?

    Does it make any difference whether you shift up, from 1st to 2nd, or down from 3rd to 2nd?

    Maybe check where the gearlever enters the gearbox - some boxes have a nylon bush/ball that can wear out.

    And sommer get some.Unihlide from Henri Stoffberg to make sure everything inside the box is as smooth as can be.
    I have met some crazy people. They have made me their leader...

    1st to 2nd is rough , 3rd to 2nd is smooth.

    Double clutching makes no difference when upshifting.

    Laugh at me if you want to, but try 5% Uniglide FRC in that box. Plenty of evidence of how well it works.
