BUILD THE ULTIMATE, TOUGHEST TORQUEFLITE
WITH A&A TRANSMISSION COMPONENTS, YOUR TORQUEFLITE CAN BE BUILT TO HANDLE MASSIVE AMOUNTS OF HORSEPOWER.
With A&A Transmission components, your Torqueflite can be built to handle massive amounts of horsepower.
When we began searching for an A-727 Torqueflite to hold up to the 825hp Ray Barton–built Street Hemi going in our ’65 Coronet, we found most transmission companies claimed their units could only support up to 650 naturally aspirated horsepower. These same companies do offer transmissions and components for Brand X folks that can handle over 1,000 hp. What’s a Mopar guy to do?
We called A&A Transmission. It offers the kind of hard-core components that’ll enable the Torqueflite to withstand power level ratings of up to 1,600 hp. Enter Rick Allison (proprietor of A&A Trans). We know of no man on earth who has dedicated the years of research and development to produce the parts to toughen-up the Torqueflite transmission. In today’s world of race- and street-driven, high-horsepower buildups, it’s now possible to construct a Torqueflite with A&A Trans components that’ll take the abuse and stay together. And should you decide to go on the HOT ROD Power Tour or Drag Week, an A&A fortified Torqueflite with a Gear Vendors overdrive unit would lower engine rpm for nice highway cruising on that dream road trip.
With naturally aspirated high-horsepower commonplace and others with power adders (nitrous, turbo, or supercharger), a serious transmission upgrade is critical. Let’s be thankful a real Mopar guy like Rick Allison has devoted years of R&D to produce the strongest components available for us to continue using our beloved Torqueflite. Now that you’re reading this, you’re aware there are no excuses for us Mopar faithful to use a Brand X auto trans in our Mopar muscle car.
Whether you’re running a 904 or 727, and whatever the power level of your combination, A&A has the parts to keep your T-flite together without the fear of failure. In our situation, we wanted to preserve our ’65 A-727 cable-shift, slipyoke Torqueflite for our bench seat, column-shifted “Cool Blue” Coronet project car. Here we’ll mention some of A&A’S Ultimate components (300M steel-hardened input and output shafts, lighten billet steel drums, lightweight sunshell, rear roller bearing support, A&A’S ultimate boltin sprag, modified front pump and support with hardened front pump gears, billet servos, billet five-pinion front and fourpinion rear planetary gears, machined for Torrington bearings, Kevlar bands and clutches, with many more components you can read about in the captions) that’ll fortify our unit so there’s “no worries” about destroying our transmission case with a catastrophic explosion.
Once we complete the buildup of our B-body, it’ll see chassis dyno testing followed with foot-brake strip testing. We’re confident our well-built, super-tough A&A Torqueflite will be up to the task. Before starting the build, we asked Rick if we could use an auto shift, or a forward pattern instead of a manual reverse shift-pattern valvebody. Rick let us know that an auto shift or manual forward shift-pattern valvebody would only flow enough fluid and pressure to hold the high gear clutches without slippage to about 550 and 650 hp, respectively. That’s the reason why we see the high-horsepower combinations use a manual reverse shiftpattern valvebody, which has much more fluid flow and pressure to firmly apply the Third gear clutch pack.
Preferring a forward pattern for shifting a street-driven car, I asked Rick if he could develop a manual forward shift-pattern valvebody for our street driver. Thankfully, Rick went ahead and put in a bunch of late nights to develop and build us a manual forward shift-pattern valvebody. This special-built valvebody will deliver 66 percent more fluid flow of holding power for the high-gear clutches. Rick assured us that the added fluid flow was
enough to handle our Street Hemi’s 825 hp. After all of the R&D, this high-horsepower manual-shift forward pattern valvebody is now available for any Mopar maniac interested (are you Slap Stick folks listening?). Rest assured, we’ll have plenty of confidence knowing there’s a bulletproof A&A Torqueflite behind our high-horsepower Street Hemi. Follow along and check out how a seriously strong and reliable Torqueflite is built using the toughest components.
At Chryslers at Carlisle we brought our ’65 A-727 Torqueflite to Rick Allison of A&A Transmission for a full high-horsepower buildup. Rick will fortify our trans with super-duty components he designs and manufactures to easily handle anything our 825hp Street Hemi can dish out. Here you’ll see what goes into an A&A Ultimate Transmission.
Our A-727 was built with A&A Ultimate components rated at over 1,600 hp. The trans was safely packaged, crated, and delivered a few months after we dropped it off at Carlisle.
Here are a slew of the super-strong billet steel and aluminum components that’ll be going into our A-727. Thankfully, A&A has developed and produces these tough hard-core parts to make the Torqueflite capable of withstanding the kind of abuse from today’s high-horsepower buildups, including nitrous or blown applications.
The Oem-sintered iron/powered metal front drum has been known to explode and destroy many Torqueflites. Here are A&A’S Ultimate billet 4140 steel front/high clutch drums, which are far superior in strength. Our 727 trans will employ the lightened big piston drum (right) for better clamping force, Third gear shift, less rotational weight for more power to the rear wheels, and no fear of drum explosion.
