200+ BHP and heavy foot on std box dont go very well
thats the lay shaft bearing being killed, thats caused by slowing the car down with gears ( its true as thats what i ALWAYS do and ive done prob 7 boxes,,,,,,, NON OF EM IN A TURBO POWERED CVH AND ONE IN A 1300
5th gear is caused by low gearbox oil btw, if the oil level was right then it would still go BUT usually when holding it at high revs for a long period of time,,,,,,,,,, i done 1 box like that but i held the foot to the floor from watford gap services to the leeds turn off and the car just "poped" out of gear and i could get 4th fine, just would not hold in 5th untill i slowed down a little and the box cooled down
that box actually lasted me for 10k miles after that, but never used it on a motorway since
