The achilles heel of the Evora and Exige V6 Gearbox is the inner gearing. Specially the 4th/5th gearwheel at the input shaft. The gearwheel get´s some clearance at the input shaft and if it becomes some load, the inner gearing breaks out and you lose your 4th/5th gear.
We can repair this issue at each gear for small money. Original Toyota gears aren´t working then they havn´t the correct ratio.
