Installing a TKO into a 55-57 Chevy

This conversion will utilize the GM conversion 5sp GM TKO.  You will need to have a 26 spline clutch disk though.  And you’ll have to shorten your driveshaft, and install the C6 slip yoke onto it.

According to the majority of our customers, the trans will fit into your tunnel without modification.    I’ve had one person tell me they had to “lift” the tunnel to get it to fit.

If you have a bench seat, you will likely want the 12.56” mid-shift shifter option for $.

If you have bucket seats, and don’t mind cutting your tunnel a bit farther back, the stock shifter location at 16.75” will work.

Danchuk is selling a 5sp crossmember just for your car!  Check it out here.
