One of the more popular swaps going on lately has been the transmission swap, particularly the Tremec transmission swaps. Some factory transmissions aren’t holding up to the kind of power-adders that people are putting under the hood, and that means the first component to take the brunt of that power needs to be beefed up, too.

American Powertrain is one of those companies that can help get your street rod or musclecar beefed up, because just like engine swaps need new motor mounts, transmission swaps need new mounts as well – to the chassis and to the engine. When it comes to mating up that Tremec 5- or 6-speed transmission, American Powertrain can help you complete the job without having to do all the fabrication and running to and from parts stores all weekend.

With complete kits that include the proper shifter, bellhousing, clutch, driveshaft, trans mount, crossmember – everything you need is included. They can help your swap go a bit quicker because they’ve put everything you need into a kit. But don’t think they’re just matching up parts, because they manufacture many of the necessary parts themselves, too.Their X-Factor crossmembers for the ’68-’72 GM A-Body cars that they had on display will work for all transmissions, and is a lightweight, adjustable crossmember.

One of the more unique parts they brought to SEMA was their ISO-X Ballistic Series transmission mounts. What looked and felt more like a chunk of plastic was actually a fiberous polymer mount that can provide the type of support a solid mount provides, but has similar fluid resistance properties that polyurethane has.  They also had body mounts on display, made of the same polymer material. This stuff is typically used in ballistic armor, so you know it’s tough.

So if you’ve been thinking about a Tremec swap in your musclecar or street rod, check out the American Powertrain web site and put it in gear – because they can get you hooked up whether is for cruising or full out racing, and they have the kits to make it work.
