hsv 6 speed gearbox

[vt clubsport]

Hi guys i own a VTll Clubsport with a 6 speed manual,which i have had nothing but dramas with,im a holden boy through and through but this drama with the trans is realy getting me upset.The problem first of all is the shifter is popping out in reverse,everytime i go to reverse,secondly im loosing my clutch master cyl fluid every 4 days,(which i am unable to fault where it is going) possiably the clutch slave cyl leaking yet nothing is coming the bell housing area.lastly the box makes a funny ratling noise on deaccelleration or cruze speed (not pinging)
My question is ive been quoted $3000.00 approx to rebuild the box (that price is rebuild only) i have to remove and refit box myself,with no clutch kit included,they claim that because it is a HSV it costs alot more than a standard LS1 6 speed trans,IS THIS TRUE?????. As i dont want to be played a fool just because i own a HSV.
Please any help would be appresiated as all the manual trans places ive called dont know.I am able to pick up a good reent rebuilt box for $1500.00 but i dont want to put a standard 6 speed into it
Please help

hmm it gets you really down when things like that happen. not too sure about a rebuild, i think id be more inclinded to put a whoile new box in rather than just rebuild its internals.

maybe wait a couple more days for a few more replys.

the HSV 'box has different ratios to all the standard Holdens. although they are built tougher than the standard boxs, it shouldnt cost that much for only the rebuild, and no clutch kit. shop around if you can, there should be a better deal somewhere.

Thanks for your help guys, as you can tell ive been trying to get info from everywhere,with different good info all the time its starting to get real confusing.some guys on other forums are posting that the t56 and holden m6 are identical boxes with no strength difference at all,im not saying your wrong,as this is a HSV site with people that drive HSV's not done up holdens,but is your info 100% correct or a assumption that they are stronger because it is a HSV ??

I can assure you that your gearbox is EXACTLY the same as in any other VTII Holden (eg. "SS"). The only difference in the driveline of the Clubsport is the diff ratio (which is 3.7:1). All GENIII VTII's use the T56 manual gearbox.

thanks for you reply c4b you sound very confident about this so ill take you word and get in contact with a gear box shop and not mension its a HSV and hopefully the will give me a honest quote (not a inflated one)

Just tell them you have a VTII Commodore with a T56. I've got a VTII GTS300 and the gearbox in it is identical to the garden variety Holden one too.....

c4b do you have the same problem to i and that is "what makes a HSV different to a standard gen111", like ls1 edits am i going to get any improvment to my clubby if i do this,wouldnt mr HSV already taken care of a simple reprogram eg:mine is a 255kw why is it that a simple reprogram supposivly can garentee me 300kw

I know it sounds like smoke and mirrors, but when HSV develops a tune for the cars, they have to allow for many different variables like crap fuel, not so good engines, etc. This means the standart tune (although better than Holden) is still very conservative. Using LS1EDIT (or HPTUNERS now) in conjunction with running the car on a dyno allows the tuner to see exactly how your engine performs, and adjust timing, mixtures, etc. to be optimized for your specific engine.

My mates VTII R8 went from 194rwkw's to 226rwkw's with a MAFLESS tune without touching anything else (he already had pacemaker extractors and 2.5" exhaust both before and after).

[vt clubsport]

c4b do you have any ideas as to a couple of places that carry out this style of tune i have heard power torque are good, i dont mean to sound negative but for 1000 clams ($) is 32 rwkw going to be realy noticeable,i installed a ss induction cai and they claim that it should make "Expect up to 12kw increase at rear wheels" i feel it was a waste of money,no real notieable difference,if anything it hessitates/misses on heavy take offs.

Ironically the maximum power difference achieved with the tune is the least noticable aspect of getting the tune done (how often do you drive around at 6000rpm). There is a whole host of things that they change (tune wise) which makes the car feel much more responsive, particularly low down and midrange. You will be amazed at how different it makes the car feel.
It is well worth the money.

I agree with your sentiments about the SS Inductions CAI. Total waste of money. I bought one when they first came out and it did absolutely nothing. I ended up giving it to a mate, who also found it useless and he gave it to another mate (who now has it sitting in his shed).

Definitely go and see Powertorque, they are the only crowd in Brisbane I trust my car with.

lol! poor old ss inductions. they would have to rate up there with those other gems the Hiclones! I recon your best cai set up on a gen111 is to go to your nearest holden dealer and get them to order you in the GTS inlet pipe that seals behind the headlight and runs straight into the airbox. I got quoted $150 bucks for this set up from a bloke I know at a local holden dealer and Chipmaster in perth use this setup which they slightly modify by enlarging the hole in the air box and these cai's easily flow enough cold air for 300+ kw. The only way to go better than this is to throw away the air box and get one of the exelent ram pod setups that are currently available from companies such as chipmaster, Kostecki engine centre etc etc etc. The only disadvantage of the ram pods is you loose the stock look of your engine bay.

[vt clubsport]

is the standard vt11 hsv cai the same as you were talking about,as once again it appears that i have taken a perfectly engerneered part and replaced it with a crap part (im learning a very expensive lesson)

[wagnman]

I think the gts 300kw was the only model with that particular intake. It is the only one I have seen that is fully sealed behind the headlight from the factory. Even on my vy series two that comes standard with the same cai that only came out on the monaros on the previous models the cai is not fully sealed to the headlight and sucks heat in from the engine bay. I think the go is the gts unit or go for a sealed aftermarket ram pod but i wouldnt get a ram pod unless you are going all out on your motor with head porting and cam job etc. Forget the ss inductions set up and dont let anyone sell you on upgraded air flow meters as by the time you get them and fit them you woud be better off throwing the air flow meter out and getting a larger maf pipe and a full mafless tune. hope I have been a help.

[HSVVTIIR8]

The R8 also has the sealed intake behind the head light as well, 2nd hole mod works quite well with it, all you need is a good holesaw and then fit a pvc pipe through the gromet in the airbox through to the hole you cut into the HSVCAI. People say these work better then even the monaro air intake.
