Alex_GT Posted January 9, 2016 Share Posted January 9, 2016 Sorry to start another thread, but I have noticed another issue (?) with my car. When in manual mode the gearbox does not change down, even after coming to a stop. The guide on here states that even in manual mode it will still act like an auto when slowing and it will change down, but I have found with my car this does not happen. Another thing I have noticed that when in first gear and pulling away, the car does not accelerate like it does in the other gears. It's a bit difficult to describe but the best way I can put it is that the engine is turning over faster but the drive is not getting to the wheels, if that makes sense?

Chris88 Posted January 9, 2016 Share Posted January 9, 2016 I would think that the first thing to do would be to check the level and condition of the fluid in the gearbox. Quote Link to comment Share on other sites More sharing options...
sidewaysdan Posted January 9, 2016 Share Posted January 9, 2016 Do you have any fault codes. Maybe a speed sensor . Quote Link to comment Share on other sites More sharing options...
David P Posted January 9, 2016 Share Posted January 9, 2016 Don't expect the transmission to function correctly until you have mended the odometer issue. Quote Link to comment Share on other sites More sharing options...
Alex_GT Posted January 10, 2016 Author Share Posted January 10, 2016 I didn't realise that would effect the gear box, it hasn't been fixed yet, can't seem to find anyone that can do it. The car came back from Toyota with no fault codes, and when I got the car the gearbox oil was a bright pink colour, is that good or bad?

The gearbox oil should be a dark cherry red colour, bright pink? never seen bright pink ATF Quote Link to comment Share on other sites More sharing options...

GTR Fever Posted January 12, 2016 Share Posted January 12, 2016 bright pink?? I have never seen this either. Prob got water mixed in? And David is correct, sort out the odometer issue first. That circuit is really tricky as it depends on the other units for proper function (kick down, shift up/ down, speedo, odometer etc).

David P Posted January 12, 2016 Share Posted January 12, 2016 I have heard of the in rad cooler leaking coolant into transmission, but statistically, it's more likely that the OP is colour blind? Quote Link to comment Share on other sites More sharing options...
Alex_GT Posted January 12, 2016 Author Share Posted January 12, 2016 That sounds bad, how can I know for sure that the oil is contaminated? Quote Link to comment Share on other sites More sharing options...
David P Posted January 12, 2016 Share Posted January 12, 2016 Drain the sump and take a good look at it, a drop of it in a glass will show it's colour & condition and take sniff of it too. Quote Link to comment Share on other sites More sharing options...
GTR Fever Posted January 13, 2016 Share Posted January 13, 2016 ^ as David said again...drain some oil and check it properly. Quote Link to comment Share on other sites More sharing options...
Alex_GT Posted January 13, 2016 Author Share Posted January 13, 2016 Double checked and the colour is a cherry red, not sure why I got that confused earlier. Quote Link to comment Share on other sites More sharing options...
David P Posted January 13, 2016 Share Posted January 13, 2016 Don't worry about your temporary colour blindness, can you see well enough to tell if the level is correct? If so, keep your eye on the odo problem. Quote Link to comment Share on other sites More sharing options...
David P Posted January 14, 2016 Share Posted January 14, 2016 (edited) This guide that I have added to the Transmission Group might help? http://www.mkivsupra.net/vbb/group.php?discussionid=189&do=discuss Most faults are self inflicted by poor maintenance, electrickery dickery and throttle body tinkerings. Should your transmission fail to work properly, if you have recently tinkered with any of the above, there would be a good place to start. Check list. 1. Correct fluid level is crucially important. http://www.mkivsupra.net/vbb/group.php?discussionid=188&do=discuss 2. Check for any fault codes. http://www.mkivsupra.net/vbb/showthread.php?35920-How-To-Check-the-diagnostics-codes 3. Correct signal from odometer is vital, check for poor connections on speed converter. http://www.mkivsupra.net/vbb/showthread.php?72588-Code-42-Fix&highlight=pink+wire+mod 4. Correct setting of Throttle Position Sensor is essential. http://www.mkivsupra.net/vbb/group.php?gmid=2546&do=discuss#gmessage2546 (If you have dicked with the throttle stop, you may have a problem) 5. Speed sensor signal is imperative. (See links on 2 & 3.) Edited January 14, 2016 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 14, 2016 Share Posted January 14, 2016 Stripping throttle bodies to make them shiny is the cause I see most frequently, fiddle with the throttle stops and TPS sensor factory position at your peril. Quote Link to comment Share on other sites More sharing options...
David P Posted January 14, 2016 Share Posted January 14, 2016 A throttle body is a deceptively complex component and anything on it that is factory sealed should not be dicked with, yet on many occasions this advice gets trumped by the shiny card which mostly ends up by learning this the hard way.
