Modern Driveline 1955-1957 Chevy Tri 5
Modern Driveline’s approach to the Tri 5 using a TKO five speed or T56 six speed transmission conversion from a 3 or 4 speed manual transmission or automatic transmission is quite simple.
When converting from a manual transmission, the original Chevy bell housing can be reused along with the 168 tooth 11” clutch pattern or 153 tooth 10.5” clutch pattern flywheel as well as the mechanical clutch linkage. Or we can convert you to Hydraulic Clutch release as an upgrade.
Cars equipped with automatic transmissions, will need a new bell housing, flywheel and clutch release.
Clutch selection is the next critical step. If your manual transmission is equipped with a 10 spline input shaft, Modern Driveline will select one of our 26 spline, in-house, handmade clutches matched to your horsepower and use up to 600 Horsepower.
Beyond 600 Horsepower or strip use, Modern Driveline will recommend and provide either a Tilton twin disk clutch and Chromoly flywheel or the Mcleod twin disk clutch. If you have a M22 transmission with the “Fine 26 Spline” input shaft, you may be able to reuse your clutch.
Modern Driveline will “flip” the shifter the TKO and locate the shifter to the forward socket in the rear shifter housing placing the shifter about 16.30” from the back of the bell housing. With the shifter in the correct location a “Hurst” Candy Cane shifter lever will be provided that will work with bench seats and give you that classic look.
Once the transmission is mounted to the back of the bell housing, you will use the crossmember provide that will locate the transmission to the correct driveline angle.
A slip yoke is included with the conversion package, or Modern Driveline can provide you with a steel, aluminum or carbon fiber drive shaft as needed.
Modern Driveline has figured out all the details for Tri 5 conversions for small block, big block and LS engines.
