TR-6060 6 Speed replaces T56

[Louie_D]

Alot of you would know that the T56 has been replaced by the Tremec TR-6060 6-Speed in many exotic cars like the new dodge viper and corvettes. Wondering if any of you have done the conversion or upgraded the T56. From what ive been reading you can pretty much just bolt the new box into our cars, just need to change from the 10 spline to a 26 spline?

[taztassio]

i think they are the option on the new ls3 hsvs.


meant to be a nice shifting gear box, and as you said, bell housing and shifter location would be the same...

[offshore]

Besides the W427 can you actually buy an LS3 HSV with these in them yet?

[macca33]

I believe that you can. A bloke posted in another thread that his LS3 Clubby - picked it up late December, 2008 - has the TR-6060.

It will filter down to the Holdens after a while, I assume - so if people are after a cheap T56, keep your eyes peeled, as there ought to be some surplus stock in the near future.

I believe the special edition GTS and Senator from the Sydney Motor Show marked the introduction of the TR6060 in 2009 plate HSV models.

[tuff304]

I'm pretty sure Ford are using these in all the G series cars.

[KCB50L]

just need to change from the 10 spline to a 26 spline?

Is that as in input shafts? as Holden haven't used a 10 spline input shaft since they ditched the T5 in the VS model. To my knowledge All t56 based boxes are 26 splined input shafts.

[lowriding]

Is it worth it ?? it has a slightly higher TQ rating but that is moot as the T56 is virtually unbreakable as it is ,and the bits that do break will still break ina tr6060. For all intents the TR6060 seems to be just an updated T56 .Im sure some clueless magazine reviewers might ramble on about it being so much better yada yada - just like 5 years ago when Ford fitted the near identical T56 (with a minor shift revision)to the BA Falcon to replace the T5 , the same box they sh8t canned the commodore for years was all of a sudden brilliant ,yeah bullshit ! I have actually read on Corvette forums complaints that the 6060 is not as smooth shifting as a T56 ,go figure :confused:
and Im still willing to bet a ripshifted and aftermarket beefed T56 would still be better at everything than the "all new" tr6060 .

[KCB50L]

Ripshifters are very much over rated IMO.

[lowriding]

much more precise than the stock shift .

[KCB50L]

I didn't think so, you just have to know how to use the standard shifter.

[Evman]

I have actually read on Corvette forums complaints that the 6060 is not as smooth shifting as a T56 ,go figure :confused:

In the Wheels Car of the Year article one of the Fords (I think the 6T...?) had a very notchy shift that they didn't like very much at all. Put the money into a good aftermarket shifter (plus a gearbox rebuild if need be) and reap the benefits. It'll be cheaper than a 6060

[steve_t]

Yeah, I've seen a few reviews saying the 2-3 shift is much better, but others that say it isn't. I'd say a broken-in T56 M10 with a rip/billet shifter is gonna be much better than changing to a tr6060 unless you're gonna be over 700nm in torque and doing hard launches

[indyeve]

I have an R8 tourer with the 6060 box .It is alot smoother and tighter than the t56....

[cosmo vyss]

Does the 6060 bolt straight up as a replacement for the vt-vz range? If not what changes need to be made? Even though the t56 will be cheaper but wouldn't the new box be a better option? Sometimes rebuilds can cost virtually the price of a new box, not to mention the down time without a car.

A few ppl that have driven the new 6060 box have stated its a much better shift. Noting that maybe the new box would be a better replacement option for those in the market.

I'm that "bloke" :woohoo: and I found that HSV don't put out the dealer flyers that Holden do everytime they do an upgrade. So to determine what changes may have been upgraded if your HSV model id has changed (MY8.5 to MY9.0 to MY9.5) requires some investigation and dealer help.

What I found during the day of my delivery Dec 31, upon close inspections of mine and the Booran Holden yard stock was, the 2009 MY9.5 Clubby's (which are 2009 release) with build dates of Nov 2008 onward in manual have the TR6060. Also on Clubby's and GTS's the centre console "sliding" arm rest lid has been deleted to a fixed lid, the engine dip stick has been moved slightly back toward the firewall and is more vertical, from what a mechanic said was to stop a problem of rubbing the lead causing ignition problems.

Not sure if they changed anything else, so if anybody with HSV build knowledge can assist would be pleased to hear.

Although I have only travelled 2100klm I have noticed the TR6060 is a bit notchy at cold which I suppose should be expected when it's not the stock trans Holden use in the SS and SSV but a transmission that can handle 317KW, but after warming up does become is a lot smoother than the standard Holden unit and old T56 and has more positive shifts. I expect "one day" it will filter down to the Holden range but I wouldn't hold your breath given it's just become standard fitment to the 2009 HSV.

:goodjob: HSV

Hi,

HSV MY9.5 manual trans have the new box.

Given that the Tr 6060 is the box for the yanks G8 I would bet London to a brick that Holden will be fitting them to their V8's in the very near future.

cheers

Isn't is only fitted to the GXP which is based on a clubsport?

The rest of the G8 range are still autos.

[ebbett21]

T56 gearbox out of the earlier cars VT/VX what mods need to be done so it fits and works on a LS3??

[steve_t]

I'm that "bloke" :woohoo:

Hey Mr SS V8, did they bump up the torque figure from 550nm now that the gearbox can take more?

Or would that once again devalue the preceeding models by too much? PD? :rofl:

[Marco]

So what's the benefit in the 6060 over the T56? Is it just the allegedly smoother shift (which I think is just fine in my VE anyway)?

Can anyone give any more info or confirm the above? Trying to workout when the Tr-6060 manual was introduced and other running changes between my09 & My9.5 in the Clubsport. Does anyone know the changeover date from my09 to 9.5? I wonder if you can tell by Vin# ?

Thanks in advance if anyone can spread the knowledge.

[tyrhantc]

I agree mate. Compared to the T56 in my VZ SSZ, the T56 in my VE is light years ahead in quality and feel of gear change.

Supposed to be better 2-3 shift as well has a higher torque capacity rating but I've yet to hear of any broken T56 M10 'boxes

[Excellent]

I've never been able to work out if the shift is a problem with the shifter itself or the gearbox? Why else would one opt for a shifter if it doesn't improve the shift action? Holden must be using crap shifters. Have the manuals in the Fords also been poor shifters?

[macca_779]

The shifters in the Ford T56's are a bit better than the Holden ones. But the TR6060 box is even better stock than the best shifter in the world on a T56. I had a play with one in a FG XR6-T and its magic compared to the old T56.

I want one when I replace my T56.

[Dug]

Dude,
Our VT T56's are definatelly the worst feeling shifters out of a stock car possible. I'm positive the only reason that Holden got away with releasing a shifter that felt like that was because the LS1 motor was so hyped, and such a huge power increase over the previous V8, that it was either largely ignored, OR was deemed necessary to hang onto that much power by the general public.

ANYTHING would be better than what I've got (including the shifter in the Getz).

[macca_779]

Well it finally happened. The arse (output shaft seal) fell out of my box today. I pulled up to be acquainted with what 4.5L of Transmax looks like under my car. I was in the middle of nowhere so decided to press on and see how it would go with a further 250km to go to get home. It actually made it no worries but I'm sure there is permanent damage in there now.

Anyway. I'm going to replace the box (had other issues prior to this) and would prefer to go with a TR-6060. Anyone know for sure if they bolt straight up and approx pricing would be handy too. If its going to be to hard, I'll just stick an M12 in there as I can't be stuffed screwing around with converting bell housings, clutch plates, or tail shafts.

[rastas]

I dont know what you would get for your second hand t56 but a new 6060 is around the $6-$7000 mark i believe.

[smaky]

I have an R8 tourer with the 6060 box .It is alot smoother and tighter than the t56....

Mate maybe you can shed some light on something. My T56 rattles like a little b1tch, really detracts from the sound of the car; it's quite loud. This is normal in the T56 I've been told.

Does the "new" box have this issue?

Macca,
Talk to Mal Wood, but last time i checked there was a minimum wait for a TR6060 of 6-8 weeks as he doesn't really stock them and they have premium price also.

Cheers

[ringram]

Is the tr6060 a straight swap for the t56 in the VE?

[cosmo vyss]

What about for the vx/vy/vz cars?

[macca_779]

So far I've worked out that the 6060 runs a different input shaft spline which would require a new clutch plate, or a converted shaft. One would assume shifter mechs and sensors would be transferable but we no what assuming gets you. In any case I'll ring Mal Wood tomorrow to get some info.

I'll want the box ready to just shove in, so if there is any stuffing around, I'll just get an M12. Which is still better than what I've got.

That would be good Macca. I think the tr6060 is the go. I have driven 2 cars with that box and it is a marked improvement over the old one. I am hoping its pretty much a straight swap.

Rang Mal today to discuss options. Basically its not a straight swap but he can re configure it to suit. He also mentioned that a reco MM6 will shift just as quick, which talked me out of the idea. Then we got on to ratios. I was quoted $2850 for a stock MM6 or $4000 for one with modified ratios. That on top of $250 postage ($500 both ways being an exchange arrangement) and it was starting to add up.

I then got on to my contact at Holden and I can get a brand new M12 for $3200 delivered. You have to change the pilot bearing which is another $60. $290 for fitting as I can't be stuffed doing it and we arrived at pretty much a cool $3500.

All in all a far better deal than what Mal could do for a box with better ratios than the MM6 anyway.

[SV8007]

All,
Ive called HSV today and they confirm that all E series cars built from Sept 2008 (MY09) have the TR6060 in them.

[Jarhead]

All FG XR6/8, F6 and GTs run the TR6060 gearbox.

All HSV manuals are using the same box as well, although the linkages are slightly different.

The first 3 gears have triple sincros and the remaining 3 have 2 syncros (so does reverse).

The trick is finding a clutch to suit. Mal Woods modifications are worth the money - no question. From the factory the Fords use a new 290mm slef adjusting single plate clutch. On a recent track day at QR these all managed to last the day without any problems at all. I clearly remember a John Bowe drive day a couple of years ago when the F6 was first released - they used T-56 boxes with a twin plate clutch. There were 2 parked before lunch was served due to clutch failure.

[BlownLS7]

the answer to this is YES, as i have done it.

cheers paul



Is the tr6060 a straight swap for the t56 in the VE?

[Blown 454 AWD]

Both the T56 (5 Litres) and the TR6060 (3.8 Litres) come out with ATF, both have notchy changes and both like the new Mainlube 154 Synthetic Solid Boundary E P Gear Oil SAE 75w90 cold flow formulation.

We have lost count with the T56's we have the Mainlube Gear oil in and between Holden and Ford we have around 30 x TR6060 on the Mainlube 154 gear oil. (we had the 154 in Fords TR6060 longer than Holdens)

Feed back with our new formulation with changes are much smoother.

Both these boxes need the oil up grading and a bung magnet if you expect longevity out of the box, the TR6060 is suffering similar wear to the T56 because of the ATF and loading when checking with Filtergram.

Although the TR6060 is basically an upgrade to the T56, reducing the oil by 1 litre is not a great idea to a heavily loaded gearbox.

Cheers

Has anyone worked out why they tend to lock you out of third on the 2 - 3 shift at high revs unless you do a granny shift?

Does the mainlude oil stop this?

[AndrewR8]

Mate maybe you can shed some light on something. My T56 rattles like a little b1tch, really detracts from the sound of the car; it's quite loud. This is normal in the T56 I've been told.

Does the "new" box have this issue?

My old SSV rattled, hated the T56 because of it, however worked out it was the clutch and not the box. When engaging the clutch the rattle would stop. Finally got a decent clutch installed and the rattle was no more!

I used mainlube in my old SSV manual and it made the shifts much nicer and did assist the 2nd to third but was still locking out on occasions.
