    300tdi defender 130 gearbox worries

    Hi, nearly lost my defender in quicksand a few weeks back, up to the floor in sand but thankfully got her out with three winches. Handbrake had filled with sand so was locked on. Anyhow because of the dramas I thought now would be a good time to change all of the oils. I put what is recommended on castrol site for the gearbox, a red thin oil. Since I have done it I have been hearing un-healthy clunks coming from the gearbox on occasions, but yesterday on a long drive sounds have become worse. Seems worse in third gear with quite high revs, just a fade in and out, dull sounding vibration. I also now hear quite a distinctive whine when I am going down a hill in gear with the clutch out, no accelerator, just gravity moving the bus. The moment I accelerate in sounds fine, if I depress the clutch the sound goes away too.
    Could this all be because of the oil change, or more likely linked to the quicksand disaster?? Hoping someone could offer some advice? Cheers Jamie p.s my bus has only done 120,000 Kms

    Did you drop the rear tail shaft and clean out the park brake drum ?
    If the adjustment is too tight on the hand brake it may be catching the drum occasionally causing weird noises when under compression or coasting.

    The gearbox uses auto trans fluid, so thin/red is right, just check what you put in. The gearbox has an oil pump in it, the wrong oil will be bad news.

    It actually uses an MTF which is heavier than an ATF. The various manuals and oil companies selectors are wrong as the ATF was superseded around '97 and the new fluid is backward compatible.

    Of Castrols oils, the preferred brew is Syntrans 75W-85

    That red stuff is ATF and too thin... MTF is what you need to fill it with.

    The original spec was for ATF but that changed in the back end of the 90s.

    Did you change the oil in the transfer case too (It uses a gear oil)? Did you get anything in the bell housing??

    I went to Syntrans and must admit it is has been better, even with a set a rings and rebuild getting closer. It used to catch going into second from third and fourth from fifth. Now is very smooth.

    Go the handbrake first, then uni joints, if the sand found it's was into a uni or two they wont last long.

    Thx fellas for your help. Yes I took the handbrake off and cleaned her out and yes I did the transfer case oil. Is syntrans a castrol oil? Will definitely check handbrake adjustment. Will also check the uni joints. How would I know if I got sand in the bell housing?

    Hi Jamie - The whine description you gave (coasting with clutch in and engine idling) made me think of diffs.....

    Have you checked to see if anything got into the diff oil?

    BTW - where in Australia did you discover quicksand? Didn't know it existed here!

    Can happen anywhere, water comes to the surface under mainly sand, the sand gains are suspended on the upward flow of the water.

    In the paddocks around here they are called soaks, you can be driving along a grassy surface with a tractor or four wheel drive and drop straight in onto the belly of the vehicle. http://www.aulro.com/afvb/1695500-post58.html

    Watch out for it when the tide is coming into where a river or creek empties into the ocean or inland in the flat between sand dunes.

    If a person drops into it and is going down fast, it's best to lay forward in it and swim out.
