Pedroby Posted October 9, 2013 Share Posted October 9, 2013 I have a running Supra project where I have swapped a GE engine out and a GTE J-spec autobox engine in. After a lot of problems with an Aristo loom on a Supra engine (my advise...never try!) I found a Supra loom and the engine is running smooth now. But the autobox is not shifting as it should. It seems like it's missing signals or sensors to shift gear. The gearbox fluid have been changed with the Toyota right spec gear box fluid so that might not be the issue. Could it have something to do with the ABS that is missing on my car that the ECU is missing some info when to change gear? Please I need help!! As the car is already standing still for almost a year now!! specs: J-spec Supra engine GTE stock twins Supra autobox Many thanks in advance!

np89 Posted October 9, 2013 Share Posted October 9, 2013 DOes the autobox not have its own ecu usually right beside the main ecu? Link to comment Share on other sites More sharing options...

V8KILR Posted October 13, 2013 Share Posted October 13, 2013 Is the Supra loom you got for the TT auto or a manual TT? If its a manual there's your problem. Link to comment Share on other sites More sharing options...
David P Posted October 13, 2013 Share Posted October 13, 2013 (edited) GTE auto transmissions have 4 solenoids and GE auto transmissions have 3. I think you're trying to operate a 4 solenoid system with a 3 wire ECU or loom? Only way it'll work is to Hybridise it. http://www.mkivsupra.net/vbb/group.php?groupid=57 Edited October 13, 2013 by David P (see edit history) Link to comment Share on other sites More sharing options...
