TubbyTwo Posted November 29, 2012 Author Share Posted November 29, 2012 Don't know what oil is in there at the moment so will flush and replace with the Toyota recommended. Was a big help today! Link to comment Share on other sites More sharing options...
andz222 Posted November 29, 2012 Share Posted November 29, 2012 get some AMSOIL Super Shift Racing Transmission Fluid in it Link to comment Share on other sites More sharing options...
David P Posted November 29, 2012 Share Posted November 29, 2012 (edited) "Chap" thinks you should try it with another ECU. This is not far from you, try before you buy. http://www.mkivsupra.net/vbb/showthread.php?278277-TT-Auto-ECU&highlight=auto+ECU Edited November 29, 2012 by David P (see edit history) Link to comment Share on other sites More sharing options...
Ian C Posted November 30, 2012 Share Posted November 30, 2012 Agreed, a simple ECU swap is a 2 minute job and quick to test as well Link to comment Share on other sites More sharing options...
TubbyTwo Posted December 1, 2012 Author Share Posted December 1, 2012 Will drop Rob a pm as he has a few bits i want. Going to drain and refill the box to correct level tomorrow. Spent a few hours last night reading through autobox problem posts. Its possible that the box can slip with too little or too much fluid. Link to comment Share on other sites More sharing options...
TubbyTwo Posted December 3, 2012 Author Share Posted December 3, 2012 Noticed something tonight, I no longer get the beep sound when the car is reverse. Going to source another autobox ecu and try that. If not will swap the whole autobox out. Drained some fluid out and its a very dark red. problem is if i have knackered the box don't want to replace the oil if its going to be a waste of time.

Littler Posted December 3, 2012 Share Posted December 3, 2012 Definitely sounds ECU related with the reverse beeping noise disappearing, as that would surely remain even if the box had gone as that is engaged based on the gear selector position which is fed through the ECU?

Ian C Posted December 4, 2012 Share Posted December 4, 2012 Hopefully the autobox ECU then, as it'd support that being the problem area. Link to comment Share on other sites More sharing options...
TubbyTwo Posted December 4, 2012 Author Share Posted December 4, 2012 Im just waiting for my next free weekend and hopefully will pop over to see RobD for the auto ecu, unless I can find anyone local with one to try. Link to comment Share on other sites More sharing options...

andz222 Posted December 4, 2012 Share Posted December 4, 2012 when you say auto box ecu is that the main cars ecu or are there two seperate ecus? Link to comment Share on other sites More sharing options...
TubbyTwo Posted December 4, 2012 Author Share Posted December 4, 2012 There are two ECU's in the passenger footwell mate, one is the main ECU the other is the transmission ECU, these differ between TT autos and NA autos. Link to comment Share on other sites More sharing options...
David P Posted December 4, 2012 Share Posted December 4, 2012 Try both, one at a time, gearbox ECU first. Link to comment Share on other sites More sharing options...
TubbyTwo Posted December 4, 2012 Author Share Posted December 4, 2012 If it does turn out to be the autobox itself, now could be a good time to go manual I guess. Link to comment Share on other sites More sharing options...
TubbyTwo Posted December 4, 2012 Author Share Posted December 4, 2012 Just looking back through some project pictures of mine and noticed the ECU's in the passenger footwell. The car is an NA-TT, so there is a GTE engine ecu, but the transmission one is a 2JZ-GT ecu. Is this a non turbo auto ecu? or were they all the same?

Littler Posted December 4, 2012 Share Posted December 4, 2012 Will point out though that the engine ECU is on the right and the auto transmission is on the left Link to comment Share on other sites More sharing options...

Ian C Posted December 4, 2012 Share Posted December 4, 2012 Yup, the right hand one is the main engine ECU and if it said 2JZ-GE I'd be worried but 2JZ-GT is fine, it's the turbo one. If swapping out ECUs don't work you might have to go down the tedious route of checking the signals/resistances on each sensor wire at the ECU, see what it's seeing. Or just swap the autobox for a known good one as it's probably less trouble Link to comment Share on other sites More sharing options...
