This method used to be all the rage, and the reason was simple: money. OPTION 1: Buy an LT1 T-56 and then convert it for use with your LS. Since most T-56s are fitted behind some variation of GM’s LS V8, we’ll assume that our hypothetical build is going to use one as well. To ID the particular T-56 transmission at hand, simply look at the tag bolted to the left side of the box.īut first, let’s walk through a few T-56 swap scenarios. How do you pick one? Whether you’re junkyard scrounging or ordering online, our ID chart should help you pick a transmission that will match your engine and provide the proper gear ratios. So, you’re sold on a T-56 for your next swap. It’s longer than the standard Magnum and was originally intended for the S197-chassis Ford Mustang. For greater flexibility, both versions of the Magnum feature multiple shifter locations and two different speedometer inputs. The GM box is a bolt-in replacement for the 1998–2002 F-body, while the other is designed for the 2003-’04 Ford Mustang. Here’s the CliffsNotes summary: all the benefits of the TR-6060 but designed for aftermarket customers, meaning it fits wherever a T-56 will. The T-56 evolutionary tree isn’t limited to the TR-6060, though. Unfortunately, the TR-6060 carries a relatively high cost and lacks availability on the used market.
By 2008 it had superseded the T-56 on showroom floors, and it can be found in applications like the Dodge Viper, Dodge Challenger, and every current GM muscle car except the Corvette. As a result the TR-6060 features bigger gears and bearings, better shifting hardware, and a new synchronizer arrangement. What about the TR-6060? It was designed as a T-56 successor, with the goals being smoother gear changes and the ability to handle even more torque.
No matter what you want to do with, in, on, or around a T-56, there’s somebody offering a bolt-on solution. It’s also reasonably light, features two overdrive gears, can handle a lot of torque, and easily fits today’s most commonly swapped engine, Chevy’s LS small-block V8.Īll of this adds up to another reason to love the T-56: lots of aftermarket support. Why is this transmission, out of all the gearboxes ever made, so popular? There are a few reasons: For one, the transmission was built in fairly large numbers. In a world that seems to be more and more polarized, at least Ford and Chevy fans can agree on the T-56. Aston Martin and, yes, Ford, have also used the box. Most of those variants are indeed found in GM cars, but not always. By American Powertrain’s count, there are 39 flavors of T-56 in the world, not counting its later offshoots, the TR-6060 and T-56 Magnum. In addition to GM’s F-bodies, this transmission has also made appearances in the Chevy Corvette, Pontiac GTO, Cadillac CTS-V and Chevy SSR, but that’s just the tip of the iceberg. The T-56 has been primarily associated with GM products. Despite their new mommy, internally the transmissions are identical.
T56 TRANSMISSION MANUAL
Tremec bought BorgWarner’s manual transmission business in December 1996, and since 1998 the T-56 has been built by Tremec. Initial reports? It was a tough, modern gearbox. A year later GM started using it in the Camaro Z28 and Pontiac Trans-Am. It was originally designed and built by BorgWarner for the 1992 Dodge Viper. To understand the T-56’s popularity, let’s start with its birth. The T-56 is their bread and butter, and it doesn’t hurt that they’re also the world’s largest Tremec dealer. To get to the bottom of this aluminum-cased wonder, we roped in the experts at American Powertrain. You can’t enter a forum or a salvage yard without hearing those three characters discussed with hushed awe and respect.īut not all T-56s are created equal, and what may seem like a great bargain might actually be the opposite. It’s the basic designation for the gold standard in domestic six-speed, rear-wheel-drive, manual transmissions.
