Built Manual Transmission

Ccarver

What I have seen on even OEM units is the clearances are all over the place. First step I take is to measure and blueprint all the parts and replace any out of Spec. I am working on a supplier of Carbon lined syncros for 5/6 gears. I have built several units with tighter clearances using shims or machining to set proper clearances. Increased detention in the shift rails, and spending the time it takes to assemble all of the parts so that the unit is tight and aligned to handle the abuse of racing or track days. All new seals, bearings are check for run out. I also have been testing with micro polishes on the gear surfaces to improve fluid flow and abrasion resistance.
