are there anything you can do to improve high rpm shifting with a TL short of removing it or swapping for something different.when i wind up past 6000 my trans gets harder to shift.it makes me lose a lot of et with the slower shifts.trans is fresh,new shifter,clutch,flywheel.if i stay below 5500 its shifts great
I've experienced the same high rpm shift problem in the past. I have a David Kee aluminum case Toploader. 5 years ago when replacing some internals of the TL, I spoke with David Kee and described my high rpm shifting issue. One of his suggestions was to use 400 grit sandpaper and uniformly work the entire cone of the blocker rings. He advised holding the sandpaper wrapped against the blocker ring, and rotate the blocker ring in one direction. I did that and I feel it definitely helped.
I re-assembled the TL. I ditched the McLeod twin disc clutch, and replaced it with a Ram long-style PP and single clutch disc. The TL now shifts as well at 7,000 rpm as it does at 3,000 rpm.
