http://www.ashcroft-transmissions.co.uk/index.html Hi Pat , it`s all new to me but what i was sorta suggesting was maybe the trans rebuild is the problem and maybe a chat with the recoer is in order . Do you know if yours was rebuilt , trans /converter or was it change over . If you still have the 3.9 have you had a look at the centre bearing in it if it ran with the rebuilt trans/converter at all . Because of the Ks on the 4.6 if the 3.9 ran it and that`s where the problem lays , the 3.9 should tell . I know the 3.9 may be a bit used but i just had a jemmy with a screw driver on one in the shed that has about 250K on it and there is no seeable movement of the crank . The sumps off it and on the engine stand , so was doing it at either end . Do you know of Ashcroft Transmissions in the UK , i`ve only read of them but they seem very knowledgable on Zfs as well as other things , they also seem very approachable . If what is happening with your is actually trans/converter related i`d expect they would have heard of it . Send them an Email ? Link to their site on top . I think anyone you ask you need to not tell them what you suspect first though to see if it is at all common nowdays as i say i`ve not come across it . Feel for ya Pat and i don`t see how you could have altered the outcome with anything you could have done . All the best , Peter . --Previous Message-- : Hi Peter : Thankyou very much for the link it probably : hits the nail on the head, even though the : tranmission and torque converter were : rebuilt not so long ago : I now can appreciate that this maywell be : the only explination as to what has gone : wrong, thanks again for your time and : efforts. : Yeah the centre bearing which has the thrust : bearings attached to the top half is the : problem and the rear side facing the gearbox : was completely worn away. : F&%k, looks like I have to rebuild the : autotrans, torque converter and engine : again, just what I needed. : Regards:- Patrick M. : --Previous Message-- : : : Pat , the link should work have a read . : : Note the dates given 1980s , things may be : very different by 1992/3 . : : I seem to remember you saying your trans was : rebuilt recently . : : I wouldn`t have thought a converter could : balloon but this suggests they can and being : ZFs run high pressures ? : : Spent some time googling and nothing like : your problem being Rover specific could be : found and if a fault is common it is usually : well reported . : : Still think the centre bearing should be the : tell though and it should be one side worn : more if the diagnosis is correct . : : cheers : : : : http://www.gnttype.org/techarea/transmission/trantsb.html : : :
