den1 Posted September 28, 2009 Share Posted September 28, 2009 This is very interesting! But Would anybody know how to correctly check the Auto Gearbox oil level? Does the engine have to be running? Or Static? Quote Link to comment Share on other sites More sharing options...

Kaan W Posted December 31, 2012 Share Posted December 31, 2012 Interesting... Has anyone tried a Uk spec manual diff on a GTE auto? Would it bolt up to the prop or is it a different flange? I am willing to test the acceleration difference if I can find one.... Quote Link to comment Share on other sites More sharing options...
Josh42 Posted December 31, 2012 Share Posted December 31, 2012 The flange is different mate but you can mate the front half of the manual prop with the rear half of the auto prop..... Or get a custom prop made up:) Quote Link to comment Share on other sites More sharing options...
Kaan W Posted December 31, 2012 Share Posted December 31, 2012 The flange is different mate but you can mate the front half of the manual prop with the rear half of the auto prop..... Or get a custom prop made up:) Or the front half of an auto prop with the rear half of a manual prop If I can find a manual diff and prop cheap enough to modify i'll have to experiment. Also are the manual differentals stronger? Quote Link to comment Share on other sites More sharing options...
Josh42 Posted December 31, 2012 Share Posted December 31, 2012 Yeah, that! Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted December 31, 2012 Share Posted December 31, 2012 Its the same diff, just a different ratio so no, not any stronger. Quote Link to comment Share on other sites More sharing options...
