The 284 transaxle uses a <em>jackshaft<\/em> configuration that uses unequal-length intermediate axles to connect to equal-length halfshafts.  This is done to minimize torque-steer.  The intermediate axle on the right (jackshaft) side is about two feet long and inside a large aluminum housing.  The left side is about four inches, and looks like this:<\/p>\n<p><a href=\"\/dohcblog\/wp-content\/uploads\/2008\/11\/stubaxle.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"\/dohcblog\/wp-content\/uploads\/2008\/11\/stubaxle.jpg\" alt=\"\" title=\"stubaxle\" width=\"500\" height=\"209\" class=\"aligncenter size-full wp-image-64\" srcset=\"https:\/\/www.davidonovan.com\/dohcblog\/wp-content\/uploads\/2008\/11\/stubaxle.jpg 740w, https:\/\/www.davidonovan.com\/dohcblog\/wp-content\/uploads\/2008\/11\/stubaxle-300x125.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<p>Due to being low on transmission fluid caused by a leaking axle seal, this axle fused itself to the differential bearing because of inadequate lubrication.  Extracting it from the transaxle required the use of a 12-ton hydraulic press and splitting the transaxle in half.  The shiny part in the middle was smeared with aluminum bearing material that had to be removed on a lathe by a machine shop.  The resulting opened transaxle looked like this:<\/p>\n<div style=\"width: 665px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" alt=\"\" src=\"http:\/\/www.davedonovan.org\/pics\/284\/P5190004sm.JPG\" title=\"Getrag 284 disassembly\" class=\"alignnone\" width=\"655\" height=\"491\" \/><p class=\"wp-caption-text\">Getrag 284 disassembly (2)<\/p><\/div>\n<div style=\"width: 665px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" alt=\"Getrag 284 disassembly (2)\" src=\"http:\/\/www.davedonovan.org\/pics\/284\/P5190012sm.JPG\" title=\"Getrag 284 disassembly (2)\" width=\"655\" height=\"491\" \/><p class=\"wp-caption-text\">Getrag 284 disassembly (2)<\/p><\/div>\n<p>Such a mess, and such a waste of an extremely rare and irreplaceable transaxle that self-destructed because of a $10 seal.<\/p>\n<p>Here is an article by another guy who tried to take apart a 284 in a Chrysler\/Maserati TC.<\/p>\n<blockquote><p>Best advice I can give is NEVER, NEVER, NEVER try it&#8230;.rumored to be unserviceable by anyone but the factory, those rumors as it turns out are pretty much true.<\/p>\n<p><a href=http:\/\/www.turbododge.com\/forums\/f4\/f22\/98898-finally-opened-284-tc-trans.html>http:\/\/www.turbododge.com\/forums\/f4\/f22\/98898-finally-opened-284-tc-trans.html<\/a>\n<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>The transaxle failure that occurred in Bozeman was traced to a seized stub axle in the differential bearing assembly.
