Guest jimmy4lfc Posted May 8, 2009 Share Posted May 8, 2009 out of curiosity then, what sort of setup do you use to get the best performance out of your AUTO boxs? Quote Link to comment Share on other sites More sharing options...
Terminator Posted May 9, 2009 Share Posted May 9, 2009 To get the best out of the box, use manual mode, so you control the change points. If you have stock traction control turn it off. If you want quicker launches use power braking, but be prepared to change the fluid more often, of fit and additional cooler to the box.

Kev_A Posted May 16, 2009 Share Posted May 16, 2009 So when in manu mode and hitting the redline (approx 140 Leptons?) should the box then change in to 4th? Mine doesn't seem to do this, if you're in manu mode and giving it some beans when in 3rd it goes up to the limiter and just keeps bouncing off Any suggestions?

mawby Posted May 18, 2009 Share Posted May 18, 2009 The autobox will only change up to protect itself. Maybe the limiter is kicking in before that happens on your car? Quote Link to comment Share on other sites More sharing options...
Kev_A Posted May 20, 2009 Share Posted May 20, 2009 Does this happen sometimes? Is it ok that it does that, anything to be concerned about? Quote Link to comment Share on other sites More sharing options...
Guest Muffin-Button Posted October 18, 2010 Share Posted October 18, 2010 Yes... what DOES the red button do? It is the magic OEM NOS booster... -.- Its SHIFT LOCK! There is a whole thread dedicated to this question. Just search it! Quote Link to comment Share on other sites More sharing options...

Nodalmighty Posted October 18, 2010 Share Posted October 18, 2010 I'm pretty sure If you slam L from 100mph you'll get L. It's a mechanical selection of fluid passages in the valve block by the shift leaver. It will also engage engine braking clutch B3 which will hurt and possibly lock the back wheels. The Toyota manual for the A340E for the TT also list 2nd gear as a possibility when in L should the ecu think it required. Line pressure is increased (Solenoid 5) and accumulator back pressure modified (Solenoid 4) when in manual mode. Quote Link to comment Share on other sites More sharing options...
bondango Posted October 18, 2010 Share Posted October 18, 2010 and possibly lock the back wheels. . It certainly will lock them, great for initiating the aul auto Drift, not to healthly for the box though Quote Link to comment Share on other sites More sharing options...
dude Posted October 19, 2010 Share Posted October 19, 2010 Looking for volunteer to test this as the old jags wont select a gear if its out of their rev range:innocent: Quote Link to comment Share on other sites More sharing options...
Nodalmighty Posted October 20, 2010 Share Posted October 20, 2010 Looking for volunteer to test this as the old jags wont select a gear if its out of their rev range:innocent: I managed to select R in a Volvo loaner while doing about 60 mph. That locked the back wheels and engine. Now I thought you couldn't select R while moving forward, alas not. Fortunately the box survived so the garage was none the wiser.

pbryant_knight Posted March 17, 2012 Share Posted March 17, 2012 Sorry to resurrect and old thread but i have a question. I might be being a little bit thick here (and i probably am) But does the Manu button make it into a sort of poor mans tip tronic box? Ie: you can maunually change up and down through the gears at will using the shidter? The reason i ask is that ive been told on several occasions that manually changing through an autobox all the time can damage the box. (also can you keep the gas pressed or do you need to ease off like in a manual) Cheers Peter. Quote Link to comment Share on other sites More sharing options...
safcdixon Posted March 17, 2012 Share Posted March 17, 2012 Pushing the Manu button makes the auto changes longerso it goes too higher revs before changing, using the 1,2 on the auto shouldn't get any damage as long as you don't abuse it for example drop into a lower gear whilst doing 90 etc Quote Link to comment Share on other sites More sharing options...
pbryant_knight Posted March 17, 2012 Share Posted March 17, 2012 Ah, i see. That doesn't make any sense though?? Why call the button "MANU"? Why not have it marked like the one in my 300zx that says "Power". A much more accurate description of the buttons function Quote Link to comment Share on other sites More sharing options...
safcdixon Posted March 17, 2012 Share Posted March 17, 2012 (edited) MANU mode does not "hold the gear longer" as it holds the gear indefinitely anyway - it shifts when you make it shift. The exception is when the stick is in D, as described above - the shifting pattern will still follow normal logic, i.e. it depends on throttle position, engine load, and revs as to when it changes gear. Lol turns out I'm wrong anyway, Apparently it makes gear changes quicker :/ Edited March 17, 2012 by safcdixon (see edit history) Quote Link to comment Share on other sites More sharing options...
ashbuster Posted March 19, 2012 Share Posted March 19, 2012 manu mode in mine holds gear untill i change Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted March 24, 2012 Share Posted March 24, 2012 I've already tested "does it drop down in manu mode if you select too low a gear for the revs". The answer is no it doesn't it remains in a safe gear until its safe to change. I've done it in both an N/A and a TT and an aristo. Yes the back wheels lock a little bit as they are going marginally slower than the cars rolling speed when it goes in gear. I have "pre-selected" the lower gear as I've headed into a corner on tracks which leaves both my hands free on the steering wheel and one less thing to worry about as I approach a corner. On the way up the rev range it will stay in gear and bounce off the rev limiter all day long until you change up. If you leave it in D in manu it will use the lower gears but will change as soon as it can into the higher gear. In manu mode it will not change down unless the revs get to a point the engine will cut out. Strangely my TT used to pull strong in L from standstill and then halfway through second would pull stronger if I switched it back to auto Quote Link to comment Share on other sites More sharing options...
SilentAgro Posted April 1, 2012 Share Posted April 1, 2012 I was testing the car out a bit today in MANU mode. I had it held in second gear, i was accelerating as much as an NA can. I noticed that the RPM's were at 8k. My car is just an NA Auto. Should the rev limiter not stop it at 6850? Or does the MANU mode make you rev it until it blows up?

dangerous brain Posted April 3, 2012 Share Posted April 3, 2012 Nope the rev limiter should cut in. Is your rev meter actually accurate? Quote Link to comment Share on other sites More sharing options...
SilentAgro Posted April 3, 2012 Share Posted April 3, 2012 Yeah I had it on the Dyno at Austec racing last sunday. It seems accurate. Is it the ECU that controls the rev limiter? Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted April 5, 2012 Share Posted April 5, 2012 Er yes! More appropriately the map within the ECU sets the rev limiter and it should come in irrespective of gearbox selection mode. I'd be very surprised by a supra going to 8k RPM without head and valvework. I certainly wouldn't want to try it more than once that's for sure.

SilentAgro Posted April 5, 2012 Share Posted April 5, 2012 Yeah thats what I had thought. I won't be going upto 8k ever again. I really don't think the engine has had any work done to it. Quote Link to comment Share on other sites More sharing options...
Guest RoxyTT Posted May 18, 2014 Share Posted May 18, 2014 Probably a silly thought, but is there way a to program the box to auto down kick/blip(not just down shift) based on speed, rpm and torque conversion? When I first had an auto, I actually thought it was how they worked. You dropped to a certain speed/tach range and it would down kick/blip for you. I suppose that's something from newer boxes found in more exotic cars? Quote Link to comment Share on other sites More sharing options...
Annabella Posted February 22, 2016 Share Posted February 22, 2016 Great thread explains a good bit. So in theory on a non TT auto, on a track day, manual mode should be selected and 2, so coming into bends revs should be right to allow a balanced throttle through the bend unless a v tight hairpin?
