Do you really want to powershift?

[Unit 5302]

Powershifting won't make a difference T-5 or TKO. The powershift is hard on syncronizers, not gears.

In a properly executed powershift your rpms should only climb maybe 300rpm. It should be all and done in a split second. If you do it to slow, you'll be basically dropping the tranny, which can cause the wheels to break loose easier. The longer you take, the longer you aren't accelerating as well.
