Davey1000 Posted October 10, 2011 Share Posted October 10, 2011 I have a Discovery 300TDi (now a "project car") and before the head gasket blew, I noticed a problem with the transmission. In 5th gear with a trailer at 60mph there was terrible "lash" or jerkiness and it was very unpleasant to drive. In 4th gear it was OK. One school of thought is that the gearboxes are worn out. Where should I begin in searching for the play in the transmission, or could it be the clutch plate buffer springs? I do have a Range Rover gearbox available but will this fit? Best regards from David. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted October 11, 2011 Share Posted October 11, 2011 I would start with the LT230 input gear accessed through the plate on the back. These wear the splines on the gearbox output shaft if you have the old non drilled input gear, I don't know if this affects discoveries but is very common on defenders with the same running gear.
