Vaughany Posted February 9, 2004 Share Posted February 9, 2004 Advice please I was reading this on a previous thread refernce changing gear whilst in Manaul mode on a Auto. It stated that when driving in manual mode you should take your foot off the throttle when changing from L - 2ND - D. Is this true, i have been keeping the foot to the florr when I change up through the gears. I thought this method would be quicker etc so more speed would be reached much quicker. Please tell me this true, otherwise have I been causing damage to the gearbox etc whilst changing gear while the accelarator is to the floor. This question never really got answered on the thread. Some said you should takre your foot off, some said you can leave it on. At the strip, what do the Supras do, surely taking your foot off the accelarator you loose power and ultimately forward momentum. What do we think and what do we/should we be doing Thanks Quote Link to comment Share on other sites More sharing options...
FaithStalker Posted February 9, 2004 Share Posted February 9, 2004 .... and the other question should be, should you take your foot of the pedal when you turn off the MANU button in 'D' in order to engage 4th gear when you are about to max out the revs in 3rd ! (this is with the o/d button OFF (out)) Quote Link to comment Share on other sites More sharing options...
Barry Posted February 9, 2004 Share Posted February 9, 2004 Well I dont! Why would you? It still changes gear the same as it would if it was in full auto mode, its still an auto box. As far as I'm aware MANU mode just allows you to select the gear rather than the ECU deciding.!? I also find it selects the next gear quicker, the faster you are going.] Also, when you are in 3rd and in MANU mode, still accelerating, then flick MANU mode 'off', the revs shoot up another 200rpm or so (before you engage OD), and no, I'm not pushing the accelerator any harder.

ISTR than MANU mode does not use the throttle butterfly to reduce the power slightly duringa change thus putting more strain on the drivetrain.

mawby Posted February 9, 2004 Share Posted February 9, 2004 I've just looked at my owners manual and it doesn't state anywhere that you need to remove your foot from the throttle when changing gears. The only reference it does make "Never put your foot on the accelerator pedal while shifting" is when its talking about moving the lever between P - R - N - D.

Barry Posted February 10, 2004 Share Posted February 10, 2004 I remember asking the same question when I first got my Supra. Something along the lines of...... "To get a fast launch, can I just rev it to about 4k and chuck it straight into Drive!".... I think most people laughed and asked if I liked my gearbox!!! Well, I've never lifted off while shifting gears on the move in MANU mode and I've been driving it almost 2 years. And I do tend to use MANU mode alot. I'm sure JB also drove it the same when he owned it*. * - Just want to say that he didn't actually own in, cause he drive's a UK spec now so wouldn't stand a chance!

trooper Posted February 10, 2004 Share Posted February 10, 2004 The gearbox is computer controlled, everything that needs to be done is being done. There is no need to lift off between changes no matter which mode the 'box is in. Lifting off and re-applying will confuse matters and probably make for some pretty jerky progress.

Friend had a couple of Trans-Am's and used to massive burnouts by dropping it into N at about 20, revving it then back into drive. After a few goes there was a bang and the car coasted to a halt. The diff had disintegrated Basically if you don't move the stick you shouldn't be able to break the box. Quote Link to comment Share on other sites More sharing options...

I don't think they manually change gears anyway. I think its OD off, maybe manual off as well and then fire it down the strip flicking OD on if you manage to require 4th gear. Would be impressed if you need 4th, that woyuld be a trap speed of >120ish MPH. This is mucho for a standard car Quote Link to comment Share on other sites More sharing options...
