tiptronic into a VZ exec?

[Summer-Sickness]

just wonderin if a SV6/Calais tiptronic gearbox would fit straight into an Exec?
and also what i would be lookin at in terms of price.

[f1tzy]

If your going to do that why not throw in a manual

[Troy711]

I honestly think it is hardly worth it unless your 4 speed shits itself, seems like a waste to replace a perfectly good mechanical component just to get an extra gear and steering wheel buttons.

[f1tzy]

That still shifts crap

[danja]

Quite possibly it'd be cheaper (not to mention easier) to sell the Exec and just buy an SV6 . Then you'd get all the other goodies that come with it, like sports suspension, better engine, higher interior spec etc.

[PaulSV6]

Get an SV6 manual

[Torquative]

or be happy with the 4 speed auto

not much but its still fun if you know how to drive it right

[MattB-05]

yea i got the VE SV6 5spd and seriously not worth upgrading 2.. from the 4spd. It almost feels like there is too many gears or the ratio's aren't right because every 5sec it wants to change. If you have a slight climb in the road it will drop a gear not hold it even with "sports shift" on... Manual will give u the ultimate control and chew up less power. Through my experience with the "Semi-Auto" I am going full manual with the next one.

[Ewok]

heh, thats because it's a VE (read: house-boat). In the VZ SV6's the auto box DOES hold the gears until you "manually" change them.

As for the gearbox itself, the SV6/Calais don't actually have tiptronic, it's active-select (pretty much the same thing but meh). You'd have to change the steering wheel, get a new clockspring for the wiring for the controls (for the flappy paddles and the audio controls). The gearbox itself is MILES ahead of any 4spd auto in the holden range (I can genuinely say this as I have owned a VS auto, have driven some of the VT/VX's and know from experience). But to be honest, as someone else has already said, it would probably be cheaper to sell the exec and buy an SV6 than it would be to put in a new tranny and change everything. Better from the motor perspective aswel.

What if i wanted to put one in my VY SS?

I have a feeling the first gear bands are rooted, or on their way out. Can anyone tell me what the conversion is worth?

[Ewok]

The boxes as far as I am aware can handle something up to around 450nM of torque? correct me if I am wrong but from what I remember

I wouldn't bother its a box made for a six so it would be luck of the draw how long it would last behind a motor with power and torque

It might last you about a week if you take it easy haha.

They are only rated to 340 Nm of torque which happens to be the 190/195 maximum torque rating.
Im sure they can handle a bit more but I wouldnt want to push it too far.
A good way to tell with the Gm transmissions is in there codes as in 5L40E = Aprox max 400 NM and 4L60e = Max 600 Nm torque - Rough guide but gives you an idea.

The transmission is also a very expensive unit, its built in france in a vaccum sealed room and worth approx $5000 - $6000 to replace.
Would prob be cheaper to get the Gm 6 speed auto box, alothough I dont know how much they are worth.

[soop]

ah well then the 6speed is an attractive idea.
As I said, I really suspect my 4speed is on its last legs, and if I have to pull it out. I'd like to upgrade it.

[MattB-05]

heh, thats because it's a VE (read: house-boat). In the VZ SV6's the auto box DOES hold the gears until you "manually" change them.

Pretty sure its the same trans in both the VZ and VE SV6's... All they did was change the paddle shift on the VZ to a sports shift on the VE... but its not even close to the manuals ability anyway. The autos can consume up to 10rwkws+ and have a mind of their own sometimes, so... I would much rather be in control of what my trans is doing.

[soop]

10kw@rw is nothing if you fudge a shift in a manual.

Fully manualised auto would be fun. Probably cheaper to rebuild a 4speed to those specs than buy a six speed.

Not going to happen unless you take the box and everything out of the Calais (5sp) and replace the 4sp totally. I think if you have to ask then you probably can't as the electrics would take very advanced knowledge of those systems.

[BullittSV6]

Yeah, much better off buying a VZ SV6/Calais, a lot cheaper and a lot less of a head ****! Or better still buy a manual. After living with my car for a year and driving quite a few manuals in that time, manual ftw! The 5 spd isn't bad but its not the ducks nuts in terms of transmission choices.

[Ewok]

Yeah matt, same box' different software driving it from what I can tell. If yours won't hold a gear no matter what you are doing, mine does. I can hold mine in any gear all day long (not that you'd want to but still...). And andrew, spoken to impulsive lately? Still running the same STOCK auto tranny.

[f1tzy]

Which wont shift properly under wot

[Ewok]

But still the stock tranny all the same. Needs shiftkit...

mine will hold the gear and even hit the limiter sometimes but the issue is not that it holds the gear when accelerating but as soon as u lose speed for whatever reason it drops back which isnt always a bad thing but its just not the same freedom as a manual there is a reason why its called a semi-auto. The famous line - "A true sports car has 3 pedals" is true. Manuals can take a lot more torque then most autos.. and the only thing autos are gud for is drags... because of shift times.

And u cant get a "fully manualised" automatic otherwise what is automatic about it..?

Autos are improving though with new dual clutch systems on most performance euro cars replacing the torque converter... as they chew up less power and shift incredibly fast. But this tech wont be seen in a Holden for a while yet.

[Ewok]

And by the time it does hit the Holden range, there will probably be no more RWD platforms available anyway heh. Truer words never spoken in that like "a true sports car has 3 pedals". I only bought the A5 SV6 because they actually go harder than the manuals (tested both for several months and read a lot of reviews). But really kicking myself at the moment for not having a manual, really missing it

[andrewmac]

And your point would be ??
Doesnt mean that it wont break, those superchargers dont give the power the same way a V8 would and it has only been supercharged for about 6 months.
Im Just going off the recommended torque rating that is provided by GM, As i said they can probably handle a bit more but the more power you put through them the more likley they are to break.
There is no way it would last long on a V8 with any decent power, if it could, holden probably would have used it with there V8's

[Ewok]

Not saying I disagree, but a lot of the time the restrictions companies place on parts are conservative and there to cover their own asses should an item fail. The fact that you can put more power through that the "recommended" and still have it reliable (for the time being heh) is just saying that what you are told you can do is not always necessarily what you are able to do.
