Slow is smooth, and smooth is fast.
Shifting fast is for losers lol. Its probably the reason so many of your trannies fail kev lol.
i dont shift like that in my TD..
i can be nice to a trans, and the bearings still die..
when decelerating, the gears change directions of thrust..
when accelerating, you use the bigger set of bearings to take care of the thrust..
and when you decelerate, the other set (smaller ones) takes the thrust..
and i down shift ALOT to slow down.. thats my main means of slowing down.
my trannies all still work fine.. all 5 gears work. reverse is trashed in a couple of them, but ALL of them are extremely noisy going down the road, and at idle..
