Hi Ive a problem progressively getting worseon 3.9 v8 disco(133K) on zf autobox the gearchanges are getting far more noticable than they used to be. the 1-2 shift hesitates slightly and the top gear lockup lurches under low loads or slight overrun conditions. The change down from 4th at about 15-20 mph is very noisy there is a very noticable clank comes from the rear of the gearbox around the handbrake drum/ propshaft area. Kick down sometimes can sound quite harsh quite a large Thud when changing down .I have done all of the usual checks like suspension bushes ball joints etc and cannot find any problems there.There does seem to be excessive slack in the take up of the transmission on the rear prop I believe on 94 MY there is a donut fitted to the rear prop.I ought to add that the mainshaft lubrication was modded by landrover at 28k this involved the fitting of new oil flinger no modded gears. My questions are How much slack is acceptable in the rear prop takeup.If the donut was fitted to the prop to eliminate this is it retro fittable to an earlier model. How likely is it that the fault lies in the gearbox. I am sure there are numerous people out there who have experience of this fault happening to themselves,I welcome any feed back I can get. Tia Al
