Silver Sport Transmissions (SST), never one to back down from an application challenge, recently shipped out their first Tremec TKX specifically-prepped for a Mopar B-body. Modifications were surprisingly minor, yet meaningful. Years of stick positioning practice have made SST somewhat of an expert, especially when paired with their STX shifters.

Where a modular shifter once stood, SST carefully machined away a pocket of aluminum on the TKX to make final fitment that much easier. The adjustment looks to be in the same shape and location as what would have been customary on the TKX’s predecessor, the TKO, so users can be sure that the mod has been trialed and tested well.

Making use of the front shifter position also proved key in kitting this 5-speed for B-body abuse. Fortunately, neither alteration will have any effect on the TKX’s 600 lb-ft of torque rating or 7,500 RPM shifting capability.

While it’s confirmed to be a no-cut fit for E-bodies, B-body tunnels will require a bit of massaging to gain the TKX’s extra gear. When it’s released, SST’s PerfectFit™ kit should handle the rest of the drivetrain details with a crossmember, driveshaft, pilot bearing, isolator mount, hardware, instructions, and more.
