Hey does anyone have any experience running 4.11s in an auto vf ss? Curious to know how the 6l80e pairs up with 4.11s on the freeway in terms of revs haha. The car is a not my daily so I’m not looking for sublime drivability here, but I’m also not looking to fully throw it away either. Cheers

Decided i'd take my ZB RS V6 (75,000km on the clock) to the [formerly known as] Holden Service Centre near me for a final service before the warranty drops dead (i think the warranty expires in Nov 2023) And thank f*#k I did.... When I dropped the car off I let them know about a couple of...

Hi I’ve got a VE Omega Ute 2012 and it only does one peggers so I assume it’s got an open-diff. I had come across a listing for a VE Sv6 sedan lsd diff and I was wondering if it is compatible with my vehicle so I can do fun stuff?

Just looking for a tip on diff upgrade options and price ranges for an Automatic Series 1 2015 VF SS Commodore Sedan I’ve already done brakes, interior/sound system/security upgrades, basic engine and exhaust with tune, etc. I’m going to start saving up for the one BIG go at the engine, but...

Recently found out my VE shitbox has an open diff. Was wondering if I could just swap a truetrac Zf into the open diff housing or if I have to get a new diff housing? Thanks fellas.

Hey all, read a lot of arrivals and Havant had a confirmed answer, am I able to put a VY SS commodore diff in a VS V6 commodore, I know I’ll have to change the yoke but will it bolt up and use the same axles, the reason I want to do this is because the VY diff I have has an lsd in it

Hey all i’m gonna get my diff reshimed , wondering how much it costs for a 3.46 diff and how long it lasts? roughly ... would be a rare skidded maybe 1 a month

Hi everyone, just a question for the Adelaide people. I have a vs statesman v8 ,does anyone recommend a good diff rebuilder? Wanting to get some gears and lsd done.

Hey guys I got a 2009 ssv commodore, with what seems is open diff, I’ve always been told that v8s are lsd standard but mine doesn’t seem to be lsd. Even tho on the diff it says (LSD Y) Could it be broken? It’s just a little confusing as I’d rather a lsd. Thanks guys :)

Hi all, done an hour or so of research with no luck. trying to find what diff my vx ss series 2 has. is it a m78 housing or a m80. cheers

Hey guys Me diffs gone, Need a truetrac, but only thing That’s got me confused is that when the workshop guy quoted me originally for a truetrac $3.2k drive away, then a week later when u called too confirm if parts come in he asked me if my diff was banging and slipping, told him yes then he...

Hey all, I'm building a m80 diff with a torque lock LSD centre with 3.46 gears for my VT S2 Calais that has the V6. Currrently has been manual converted, full MCA coilovers and cammed (just the main mods). The driveshaft is the M78 4 bolt flange, and the M80 also has a 4 bolt flange but they are...

I was just wondering how can I tell whether the diff in my VX series 1 V6 commodore auto is a m78 or m80 as I’m getting an Eaton TruTrac and need to know which one to get. In another forum post detailing diffs, it isn’t specified whether the VX V6 continued with the m78 like the VT series 2.

Hey guys, I’m having talks about who and where to get my diff upgrade done, and to keep costs low on both the labour and parts the guy I’m likely to go through suggested sourcing my own new/better diff housing for its intended use and to prevent a housing blowout should I end up doing what I...

Hey guys just wondering if someone could help me out with a problem I’m having. I have a 2004 vy commodore which I’ve just recently found out the diff is needed to be replaced and I think the right side drive shaft?After finally working out this problem I now have a new one. When coming to a...

Hi. mom looking at getting a 3.75 or 3.9 Harrop TrueTrac LSD conversion/rebuild on my 2014 Series 1 VF SS Commodore Sedan (auto), but I’m having a lot of trouble finding reputable places to facilitate this in Adelaide for any reasonable price. I know I can buy them off eBay, but all the...

Hello all, I recently broke the spider gears in my diff (Most likely) and my mechanic said that it’s cheaper to find a new diff from a wreckers than to repair the gears.? So I was wondering exactly what diff is in the series 1 VX Berlina V6 Auto’s? On another note what is a stronger diff that...

Wanting to buy a diff it’s just gonna get welded up but I’ve got a vy 3.8 and was wondering what models can I buy a diff out of and it will bolt straight up not. Don’t know much about cars so just looking for tips and advice

Fellas i got a m80 live on the vx and will be pulling diff out to spool it and been told that you have to align the diff in straight when you put it back and apparently it’s hard is this true or not ?

Hi, ive got a v6 vz one tonner, im looking at putting an LSD and 3.9:1 gears in it but im having trouble finding anything about it or even getting a straight answer. My diff is old i assume as the sticker with the details has faded to white, and theres no information on/in the car about it. Ive...

I'm in the market for a new diff for my 07 sv6 manual. I assume the only difference between the series 1 and 2 is the different ratio. I'm here to make sure I don't have any weird issues with coupling to the drive shaft ect. Cheers

Hey guys I just changed the diff in VE SS manual, from 3.45 lsd to 3.7 LSD cause we though the diff was f**ked, anyway put it all together and put it down and there’s still no power to the wheels the tail shaft gearbox and clutch are all good and the diff I just put in only done 25,000k, when...

I have a series 1 Vf SS. its pushing 315rwkw, Its a stock diff and stock drive train. I recently noticed a noise and shake coming from the rear end of the ute when I would aggressively accelerate, I can feel it through the whole car as its very excessive and is getting worse. It does only do it...

Hey guys, Ive recently changed the diff ratio in my vx commodore (ls1) from the standard 3.08 to 3.73, so now my speedos out by 18 percent or so and the shift points aren't right. Just wondering if anyone here could suggest a good place to get the speedo sensor ratio retuned to suit the new...

Pretty certain it’s diff related but it only started happening yesterday, at low speeds a clunk in the rear occurs when turning sharp both left/right, when turning right up a hill it felt like both were about to lock up but just shuddered. No whine or anything driving or any clunks 20kmh+ Drives...

Hey guys, a few days ago i noticed my 2004 vz wagon has a bit of a vibrating/shaking when under load or at about 4000+rpm that feels like its coming from the rear of the car, I thightend my tans mount to the factory torque setting and the shaking from the rear seems a bit worse now, any ideas?

hey guys, I bought 3 bottles of GM#92184900 diff oil from my local dealer as the Castrol website said it would take 2.3L, but the diff only took 1.3L. Is this normal!?? edit: i have 15k on my car and the fluid was fair grey, with a light metallic (but could just be carbon from the clutches)...

Hi all, I have a VY SS ute which I'm turning into a skidpig :D whats the best option on locking the diff ? I've seen the diff spools online but not sure if they work with LSD ? Id get the welder out but she's no banjo o_O
