Title: Who has an SMT?
Post by: Zonda_ on March 25, 2013, 20:51
How do you find them? I'm struggling with my manual due to a car crash many years ago.  I damaged my wrist which made gear changing difficult, it's been ok for a while but it's flaring back up and in my experience it lasts for a long time. I don't want to loose the fun of the roadster but a semi auto would be better. Anyone fancy a swap?

Oh no dont do it. There not the most reliable of systems. Slower too

Well if this keeps up and in my experience it will, the car will have to go.  It's the same reason I bought the auto S14a

Sorry to have to seriously disagree with that dj.

They are very reliable, so much so that if they go wrong, nobody knows how to fix them.

Whilst the 0-60 is slower than the manual, the 60-0 is much quicker so it evens out.

The real negative is if one of the three major parts (pump, actuator, ECU) goes wrong then they are about a grand each to replace.

Would I buy another one ?? Excellent system, knocks spot off the manual.

I love mine, better than any manual I've ever driven.

How do u work out the 60-0 is quicker.? Do the smt have better brakes than a manual ?

I just dont think an auto or semi auto whatever u want to call it in a sports car goes hand in hand. Its all about being a manual for me.

I agree that you dont here that many breaking but that could be because the ratio of manual to smt is about 1000 to 1?

But as said its bad times to think if something does go its nearly cheaper just to replace the car lol

It downshifts on the button quicker than you can do it manually.

Let's be fair,  how many sports cars are manual these days? Ferrari have dropped them,  lambo have dropped them,  cheaper cars like the GTR are also semi autos.

So it downshifts quicker but doesnt actually stop quicker then? Im a little skeptical that under braking from 60 in 5th gear the smt could change quicker than I could go from 5th to 1st? Obviously ive never driven the mr2 with smt but have driven a porsche and an m3 with it and the only benefit I seen was being able to flat shift. Things like traffic jams were a mare

You can't flat shift with the SMT because the ECU won't let you but there is a modification which will help.
The downshift is quicker than you can do manually. Good to be compared with systems fitted by Porsche and BMW though   s:lol: :lol: s:lol:

Awww man so u cant do the one thing with it I liked about the paddle shift system on other cars lol damn it haha

Ok what if we compare it to a citroen c2 then lol
Title: Re: Who has an SMT?
Post by: Anonymous on March 25, 2013, 22:04
To be fair to the smt its still the same gearbox and engine the only thing different is a computer does the clutch and gear shift. I have also never heard of an smt owner wishing they had the manual version. So if I was in the op's situation then yes I would look at having an smt as at the end of the day its still the same car.

Ur not kidding its insane the prices of cars that were once considered naff haha... but seriously though I think smt might be nice in a cruiser car like a beemer 5 series but not a sports car. How many times have top gear reviewed cars with paddles and begged and pleaded they make a manual version

DJ, you've made your point - the SMT isn't for you despite never actually driving one. The OP has asked for opinions from owners of SMT Roadsters. Lets stick to topic please

But even they concede it's a joke now.  Manual transmissions days are numbered,  technology has moved on.

Go for it then mate. Get an smt. However dont be planning any turbo conversions and things on the car because I don't think u can with them, think someone on here recently was looking for all the parts to convert to manual, could ask for a deal with them?
Title: Re: Who has an SMT?
Post by: AmeR on March 25, 2013, 22:22
There have been Turbo'd SMTs
Title: Re: Who has an SMT?
Post by: StuC on March 25, 2013, 22:24
I did drive an smt before I bought my first 2. Did take some getting used to and I was only driving it for 15 mins.
I would like to have another 'proper' go in one though.  :-) :-) :-)

Perhaps there is someone local to you to show you how it's done!!  s;-) ;-) s;-)

How im wiring my emerald should still work with an smt, the same with piggy backs will work with an smt so turbo is possible.

They wont take the power though will they? I know its a diff car but a friend of mine sold his edition 30 golf because he couldnt get it passed  300bhp with the dsg box in it. I heard the boxes will take whatever a manual one will but the ecu cant cope?

Don't profess to know enough to be honest but I do know there has been a few Turbo conversions done. Mattperformance may be better to advise if that was the OP's intended route as I know there's been a couple of TTETs done.

Back on Topic though please

I have Amers apexi turbo fitted to my sMt a few years back and it was fantastic! Plus there are a number of TTE turbos fitted on sMt. It can be done. You always hear horror stories about sMt but until you drive one don't knock it. They add to the roadster experience. Like with any car you buy make sure the car has full service history and you should be on to a good thing. Plus the op then can still enjoy roadster ownership  s:) :) s:)
Title: Re: Who has an SMT?
Post by: stewart@boro on March 26, 2013, 22:24
Have never driven an smt but let's consider the other alternative
You are struggling with changing gear due to physical problems with arm/wrist
I have no left elbow which results in zero flex and about 60 deg rotation of the hand( less than 25% of what it should be)
All the movement now mainly comes from the shoulder
It may be possible that with some support to the wrist may help with your problem
I am fairly local to you so if you want to chat let me know
Cheers

I've got a SMT, owned for 2 years but not my daily drive (03 plate 39k on the clock).
Thought long and hard before buying knowing the concerns but the car is high spec'ed (TTE everything, aircon, leather etc etc) so had everything I was looking for on it.
I've driven manual mk3 2's and owned a previous mk manual.
I wouldn't be put off buying a SMT, but do it with your eyes open.
I'm a button man myself – the smile gets even bigger
As others have said – what's the alternatives?
Title: Re: Who has an SMT?
Post by: filcee on March 27, 2013, 16:34
I have owned two SMT's on the trot - both from new - and been very happy with them.  In that 12 year period I have had one problem which was sorted under warranty by a local dealer running the "gearbox re-learn procedure".  At least as far as I could work out that's what they did.  Apparently the code reader reported too much clutch slip, and probably resulted from me over-babying the thing when running it in.  At the time of the problem it had about 300 miles on the clock, and I was guilty of trying to take a second gear corner in third gear as a result of me trying to keep the engine revs sensible during the running-in period.  Since then, no other issues, though it has been retired from daily driver duty for about 3 years now.

The major benefit of the SMT is being able to keep your hands on the wheel and eyes on the road whilst pressing on.  All gear changes can be completed using the wheel buttons.  On downshifts, you can afford to brake a bit later before starting to shift, which can result in higher corner entry speeds.  If you really want to push the bounds of the brakes, it's quite possible to stop from 70mph in less than a hundred yards, allowing the gearbox to downshift through 2nd to 1st for you (the only auto-resembling activity it will undertake on your behalf).

Mechanically, it is the same kit, plus a few pumps hoses and actuators.  The gearbox and clutch, as I understand it, are exactly the same as the manual car.  There is a small weight penalty over the manual, 25kg or so, but I don't think that is hugely noticeable.  Later, post-facelift (post-2003) SMTs also have stability and traction control nannies fitted.  My driving is not good enough to avoid using these, and when thinking back to my '01 SMT, they have been useful on a couple of occasions.  Note that they are fitted, but not intrusive, unlike the ones fitted to my current VAG barge.

The SMT is immense fun to drive.  For the price, there is nothing like it on the road.  Any other mid-engined, "paddle"-shifting motor will be from one of the exotica manufacturers.  I'd say try and get one for an extended test drive - 30 minutes or more - down some twists and then form an opinion if you are unsure what to do.

Best of luck with your search.

I think they actually sound quite appealing for a daily driver or tourer.  Suprised it doesn't act like an auto if you don't do anything, will it for example just bounce off the limiter if you don't bother hitting the button to shift up for example?
Title: Re: Who has an SMT?
Post by: Zonda_ on March 29, 2013, 11:00
I believe so,  they are like a motorbike in that respect,  if you don't change up the gearbox can't do it for you.
Title: Re: Who has an SMT?
Post by: filcee on March 29, 2013, 20:41
Yep, it just sits there zinging off the limiter.  Tiff proved this to be the case on an old Fifth Gear.  I've never been tempted to replicate his test though, as you're off the top of the torque and power curves by the time you get up there anyway.

That's the beauty of the SMT - you still have to drive it.  Apart from the downshift to second, then first (on the facelift), or down to first on the older models, you need to decide when and at what speed to make the up and down shifts - and you can only do them in order, no box changes allowed with the SMT.  The electronics will help match engine and road speed on the down shifts which is pretty cool, but you are still responsible for keeping the car in balance at all times, right gear at the right time, braking points, turn in points and so on.  The difference between the SMT and manual is that you feel like you are getting more time to 'fine tune' your driving because you're not having to do the revs/speed thing yourself (not that I ever could).  You are still horribly punished if you get it wrong - losing momentum through and exiting the corners so having to work harder to regain that on the next straight bit and through the next corner, or having the tail step out a bit if you allow the weight to pitch too far in a corner or when changing direction (yes, even with the electronics on the facelift this will happen - up to a point).  

It's a great car, and only loses out on the 0-60 times, in my opinion, because Toyota realised that it would need to go 10k miles between services even if being ragged to within an inch of its life at every set of lights. In my view, it was built to that requirement, by doing things like turning down the clutch engage/disengage speeds and gear shift speeds to allow the 'box time to get that part done properly before the power arrives again, and also allowing the ECU to close the throttle slightly to reduce the revs if you keep your foot in during the gear changes.  There are things you can do to 'help' it along a bit - like a little lift during the gear shifts just as you would when putting the clutch in with a manual 'box (free, and easy to learn), up to making modifications to the throttle body to remove the inertia from the components in there (costs money and you need to do it yourself).  I'm sure Toyota could have built a 'box and shifting mechanism that would have produced a better 0-60 than the manual by removing much or all of the lag introduced by the pink fleshy part of the drivetrain but achieving this would required a very high level of engineering, and building to some tight tolerances.  Ultimately this would lead to shorter service intervals, and higher costs for buying and running - in turn moving the car out of the sector it was aimed at (MX-5s et al), and into more exotic territory (Porsche et al) where it would have been a much harder sell.

Do it. If you're prepared to learn to get the best from it, its a VERY good system. Don't try and drive it like a regular torque-conv/DSG/slushmatic etc - you need to keep your manual mindset. Treat the throttle the same way you would in a manual, lift off for changes, feed the power back into the next gear etc.

I've owned mine for nearly 4 years now, and done 50k miles in it. Its by far the most involving, driver-focused 2 pedal car I have driven. Mine does this 2 or 3 times a year too...

10 years ago I bought mine... 110K miles later, running good, had the SMT ECU replaced in 2004 because it wouldn't disengage the clutch to shift (quickest gear changes you can imagine, some weird noises and stalling involved though). I'm about to do the TB mod (not the earliest adopter, I know) and still dream about finding a cheap second hand turbo kit / engine...
So happy I found out how to disconnect VSC & TRC "on demand" I hardly have them on anymore...
I still can't figure what alternative there is to this little car and wonder what I'll buy next...

I have only recently bought an SMT. I think it's brilliant!
The only thing I have noticed is that you are forced to use the central gear selector for 2nd gear when pulling off and turning.
The upshift buttons are never under you fingers when you need them.
One small detail in a fantastic car!

You'll soon get used to some odd hand positions when holding the steering wheel so you can change when turning   s:roll: :roll: s:roll:  It does take a bit of practice.

Yeah, it's only at the very extremes of the lock that you have to get creative.
A slightly smaller steering wheel would have sorted it.
