A BIG congrats to the Guys from WA that put in a ton of effort to go all the way to race in Brisbane at Jamboree 2025.
Adrians amazing HG needs no explanation and his work of art ran solid low 7s all weekend!.... and hows Lundys mustang - brand new combo first time outing and boom straight into the 7s first past and then made it all the way to the final! Unreal and credit to all the people and crew involved. When you see the level of detail and amount of work that goes into these cars, it becomes very apparent that we have the easy part in taking care of the transmissions!
Also congrats to DSRACINGs Pro Mod which was another WA car to make the trek over and run 6.0 to the 1/4! OL Jimmy J would have been a busy man keeping all this mechanical mayhem running spot on as usual with God knows how many cars to log and tune over the weekend!

We were very pleased to hear that one of our 4L60e transmissions we built for this VZ a couple of years back is still going strong, even after 1000+HP, 3 different owners and multiple 9 second quarter miles.
Recently the car has been returned to 98 fuel and thanks to Jeff Johnson from Power Management Solutions, it still makes real good power! Our 4L60e build along with Jeffs spot on Holley trans cal and Circle D Specialties lock up converter all combine to help this 4l60e keep taking all thats been thrown at it..

Where time permits we prefer to perform the trans installation to eliminate basic common overlooked problems, particularly with the electronic units that we tune to suit - even the 6l80/90 transmissions that we ship away with a recalibration, the customers are advised to bring the car back once running so we can complete the tune, as there are so many different engine torque profiles/tables depending on mods - that make it impossible to have the trans dialed in nicely independant of the car. 6l80/90 owners will know theres nothing worse than going for a drive and having your trans behave like its over in the corner just doing its own thing making its story up as you go😅
Included in pics are some of the parts needed if you want a 1000hp capable 6speed...

Some SFI gear built up and gone recently, along with some 4L80e units that vary in configuration, including a REID super 80 to suit some serious 4x4 use. All of our 4L80e transmissions have mods to solve and prevent known 4l80e problems.

We built this Pro Mod Lockup TH400 with billet bolt together converter for a one of a kind drag car a while back now, and its so cool to see this unique build developing. This car is none other than Neds unreal Billet Duramax diesel camaro!
Ned has created a seriously crazy "one of" build with some talented helpers - so much so, that the camaro is now seeing some track time all the way over in the U.S where the combo is being further developed. Top work to all involved - cant wait to see it race back in oz!

Harrop Engineering FDFI 2650 supplying the goods on top of Nicks 427cui Maloo. 1000hp+ delivered to the hubs all of which is though a TH400 trans and IRS 9inch rear.
It was some years ago we built and tuned Nicks Engine and Trans and fitted the Harrop 2650 supercharger - all which has been fine but was running the factory serp belt, low boost and 98 fuel. The Maloo still had more than enough pwr but we all know how it goes.... Finally the time was made to fit the Harrop LSA drive kit, increase boost and get some E85 into the mix, and then thanks to Shannon from Tune Corp, we were able get it on hubs and use all the throttle to the tune of 1005 RWHP Thank you Nick for your support, patience and legendary humour over years. Congrats, you have one serious Holden Ute!

Quick lil 4l60e update... Cory has managed MULTIPLE faster and faster 9sec passes to a best so far of 9.661 on a 235 radial! Awesome! and job done i reckon! Might have to get the old test rig out again in attempt to keep Cory at bay! Just in time before we change over to a 6L80e platform with much more ponies up front... stay tuned..

1000+RWHP/9.94@153.57MPH/4L60E TRANS! - Traditionally these three would not all get along ok (and pls dont try this one ...

1000+RWHP/[email protected]/4L60E TRANS! - Traditionally these three would not all get along ok (and pls dont try this one at home😂). In this case Cory wanted to add some serious power to his street car, retain as much factory gear as possible (full weight a/c etc) and see how far that idea could go.
Thankfully, Cory got the right people involved and it was all made possible. Cory had Jeff Johnson take control of the Holley power management which in this case also included full customised control over the 4L60e trans that worked hand in hand with the 4L60e we had the pleasure to build for Cory using the knowledge gained from our own 9sec 4L60e test rig. Like the 4L60E build, the trans calibration is critical and if either are not up to scratch, a combo like this wont even make it off the dyno, let alone drive multiple 70km trips to and from the track, then drive home after running a 9sec pass, as Cory did on wednessday night!
Well done Cory and nice pedal on that 9sec run!, Keep it up and we might have to get our 9 sec 4l60e parts getter back down the track!

These days, a gearbox in a fast well setup car, is not - just - a gearbox, and a torque converter, not -just - a converter.
When you find a tuner that understands what they require from the car, and has the data, knowledge and experience in this area combined with loads of other data from hours on and off the track, chances are your transmission will need specific mechanical mods that will allow the tuner to take control over the trans and get the car down the track. We are grateful to work with some of the best in this regard!
And speaking of tuning, Congrats to some of our W.A guys who managed to grab a couple of wins over the weekend against the Street Outlaws that came all the way from the U.S! No surprise in these cases here (and many others) that the man behind the tuning and power management was none other than Jeff Johnson!!
Awesome work.

Anyway, in between building transmissions. We have been able to provide/build some new supercharged engine combinations for some great customers that have made the job more enjoyable, they know who they are... so thanks again! Here are a just a few...
