Pedroby Posted December 3, 2013 Share Posted December 3, 2013 Hi guys, I have swapped my GE engine into a GTE engine, from a Supra. After some problems with an Aristo wiring loom I get my hands on an original Supra GTE loom for auto box. The engine also came out of a Supra (no aristo!!) and the auto box is Supra GTE auto bos as well. BUT the problem is that the auto box don't want to shift proper. It just shift when it want to and tried many things with the gear know to shift i different positions, but it is nearly undriveable as it backfires and keep high revving all the time. Anybody an idea what might be the problem/solution? Many thanks in advance....I want the car driving now as it's just standing since spring!!!

JasonR24 Posted December 3, 2013 Share Posted December 3, 2013 Was it an auto GE before? I think you're in for a world of issues with swapping the autobox. Was it all Jspec? Quote Link to comment Share on other sites More sharing options...
LOGIE Posted December 3, 2013 Share Posted December 3, 2013 start with basics, is there enough trans fluid? are the connectors on the auto box all fitted correctly? is the ecu connector fitted correctly? Torque converter may be at fault? Quote Link to comment Share on other sites More sharing options...
Fitz Posted December 3, 2013 Share Posted December 3, 2013 start with basics, is there enough trans fluid? are the connectors on the auto box all fitted correctly? is the ecu connector fitted correctly? Torque converter may be at fault? Took the words out of my mouth. Providing you have EVERYTHING needed and is for a GTE then I'd consider the basics. When the gearbox fluid was replenished did you move the selector through the gears first? Are the levels correct? Any loose connections? etc etc. Quote Link to comment Share on other sites More sharing options...
LOGIE Posted December 3, 2013 Share Posted December 3, 2013 Also did you fit a new oil strainer? Quote Link to comment Share on other sites More sharing options...
Pedroby Posted December 3, 2013 Author Share Posted December 3, 2013 It was all J-spec. The old GE engine was a J-spec auto and the new GTE is also fully J-spec (as far as I know the box is from a J-spec as well). The propellor shaft have been changed and the only GE auto part is the differential. But this should not make any sens I believe. I have refreshed the auto box fluid, with the correct fluid type and brought my car after some problems to a man who carried out swappings many times and brought this to an end successful! I havent replaced any oil strainers. Any pics of which ones you mean? Triple checked all connectors and they all are clicked and connected proper.

Dnk Posted December 3, 2013 Share Posted December 3, 2013 I guess you got the ecu with the autobox Quote Link to comment Share on other sites More sharing options...
mellonman Posted December 3, 2013 Share Posted December 3, 2013 also did you check the level with the engine running? but as dunk says have you got the correct TT auto ecu? Quote Link to comment Share on other sites More sharing options...
Pedroby Posted December 6, 2013 Author Share Posted December 6, 2013 Yes I have the correct ECU for an Auto bosx TT J-spec. I even borrowed an ECU to check if the ECU was broken, but same problem. Might it be the problem that the body loom is not an ABS loom? As the GTE is standard with ABS. If so I can get my hands on a body loom from an ABS car, but before I will try this first would like to discuss the problem here as it's quite a hard job to chage the interior loom completely.

LOGIE Posted December 6, 2013 Share Posted December 6, 2013 Hasnt the ABS got its own ECU? Quote Link to comment Share on other sites More sharing options...
