727 not hitting second hard enough

The linkage is for streetability so it’s not slamming every gear at low speed. Of course some ppl don’t care about that. Kim
I’ve got the TF3 in my 727, everything adjusted per the instructions (can’t recall the front lever ratio) and the kd lever wired back. Full manual, no banging or harsh shifts. Just fast immediate firm shifts at any throttle opening, on the street and strip. Always thought using the TF3 and ditching the excess was an added benefit, not having to continue fussing with linkages etc. Just an opinion is all.
