Transmission Crossmembers

A transmission crossmember is the frame-mounted support that holds up the rear of the transmission. It carries the transmission mount, sets the gearbox position and angle, and helps keep the driveline in line. People replace it when they swap in a different transmission or engine, when the factory piece will not clear new parts, or when they want a sturdier support for hard driving.

We currently have 2 transmission crossmembers in stock, one from BMR Suspension and one from ISR Performance. The BMR 1st Gen F-Body Transmission Conversion Crossmember in red is listed for T56, TR6060, TH400 and 4L80E transmissions, with fitment for the Chevrolet Camaro and Pontiac Firebird. The ISR Performance Manual Transmission Crossmember is listed for SR and KA setups in the Nissan 240SX (S13 and S14).

When choosing a crossmember, check these points:

  • It matches your chassis and model years.
  • It is designed for the specific transmission you are running.
  • It works with your mount, exhaust routing and driveshaft angle.
  • Your build does not need other parts to go with it.

To see what fits your car, pick your vehicle in the fitment tool.
