The 131/Brava 5-Spd transmission is by far the strongest transmission offered by Fiat in any of its 1970s-80s cars. It uses modern cone-style synchronizers across all gears and is the perferred choice for any 124 Spider or Coupe that is being raced or autocrossed.
Midwest-Bayless has one of the largest selections of 131 5-Spd transmission components in North America. Gearsets, synchronizers, sliding sleeves, gaskets and seals. If you are rebuilding a 131 transmission, contact us for special pricing on multiple-item purchases.
