Frank Bullitt Posted April 7, 2019 Share Posted April 7, 2019 (edited) DavidP our resident autobox guru would be the man to ask about this, here is a recent thread where the box differences were discussed -http://www.mkivsupra.net/vbb/showthread.php?352606-Uk-tt-auto-box-are-they-the-same-as-jdm Edited April 7, 2019 by Frank Bullitt (see edit history) Link to comment Share on other sites More sharing options...
J-Meiser Posted April 15, 2019 Share Posted April 15, 2019 If you have a J-Spec TT box, then the swap is plug-and-play. If you have a J-Spec NA box, then it is not plug and play, as the NA box has a 4-pin connector for the valve body and that TT box has a 8-pin connector. different flange for the propshaft (you will need a full TT auto prop) and the N/A ECU will not be able to control it, due to lack of line pressure cable and the aforementioned connector difference for the valve body. This post here should give you a bit of an idea about the differences: http://www.mkivsupra.net/vbb/group.php?discussionid=153&do=discuss Link to comment Share on other sites More sharing options...
