David P Posted April 7, 2015 Author Share Posted April 7, 2015 Nice find Gary. (Subject related page. http://www.mkivsupra.net/vbb/group.php?discussionid=184&do=discuss) "Goosed" boxes are beyond economic repair. Serviceable used T.T. transmissions are at this time find-able at sensible prices and is the way to go, look after them before they run out!

mellonman Posted April 14, 2015 Share Posted April 14, 2015 just wondering if you had a destroyed one apart before thats all dave to see what actually fails , not to have it repaired , but by the look of the video its the actual clutches due to line preasure, which you have said to me before Link to comment Share on other sites More sharing options...
David P Posted May 26, 2015 Author Share Posted May 26, 2015 I'm more interested with correct conversion and installation and correct care and maintenance, than I am with getting kacked up for nothing dicking about with dead boxes killed by d!ckheads.

David P Posted June 9, 2017 Author Share Posted June 9, 2017 ellis reported an ATF hard-line failure. Other than "metal-fatigue" I'm not sure of the details, nevertheless, it would be a good idea to include "check fluid-lines & mounts" in next service schedule!

David P Posted June 25, 2017 Author Share Posted June 25, 2017 An A340E automatic transmission is a box full of clutches and sooner or later, one of them will wear out first. O.D. is the weakest, only 2 clutch-plates here. O.D. stands for Over-Driven, and is for light-throttle eco-cruising. Always turn O.D. off for WOT driving. Always also, engage "Low" for any burnout silliness, if it gets the chance to change-up to 2nd-gear mid-burnout, it's very likely to break 2nd-gear clutch-basket. (Sprag) Avoid these pitfalls, maintain ATF correctly and the transmission should live on to become a ripe old age. Eventually, dying a slow peaceful death from slipping 3rd-gear clutches.

David P Posted July 11, 2017 Author Share Posted July 11, 2017 Appearing through Scotch mist is an example of death from slipping clutches. http://www.mkivsupra.net/vbb/showthread.php?343199-Auto-box-slipping Another one here. http://www.mkivsupra.net/vbb/showthread.php?343349-Autobox-behaving-oddly Another one here. http://www.mkivsupra.net/vbb/showthread.php?344037-Autobox-issue Another one here. The most frequent cause of automatic transmission failure is because they were owned by idiots. So unless you want to be next on the list, I suggest that you TURN YOUR BRAIN ON and read this. http://www.mkivsupra.net/vbb/group.php?discussionid=225&do=discuss XXXXXXXXXXXXXXXXXXXXXXXXXXX Link to comment Share on other sites More sharing options...

David P Posted July 21, 2017 Author Share Posted July 21, 2017 No name? No N/A or T.T. info? No mileage info? No service info? No power info? No recent tinkerings info? No fault code info? No coolant system info? No ATF level info? Not even a "garage" for me to refer to to find out what you have been too lazy or too dim to write? Maybe you think I am related to the Tooth Fairy? My best almost blind guess! In this instance, being a Mines ECU won't be any different to being an OE ECU. The problem is not the torque converter, it is the transmission. If your transmission hasn't been maintained properly, (like most Club members auto boxes) you could try fitting a new strainer and giving it a full flush with premium ATF (Not the cheapest of cheap piss that many/most Club idiots use) and add a bottle of Lucas SS. This may resurrect it for a while? Link to comment Share on other sites More sharing options...
David P Posted July 21, 2017 Author Share Posted July 21, 2017 When clutches fail, if the box has overheated this will have filled the torque-converter with muck and which WILL require replacement too. Link to comment Share on other sites More sharing options...
