Is anyone have the TKX installed and driving? How do you like it? Does it shift as advertised? Can you power shift it and beat on it? Two reasons that I may want one, don't like repairing my small bearing retainer 833 when something happens. Two, overdrive. Have read DC's thread on his install, and others. I would still do something with the cross member, even though I have a GERST front suspension.
What kind of RPM change 4-5th?
I have seen some TKX reviews on youtube where guys swapped into Fox Mustangs and show test driving and providing impressions of how it shifts. Not a Mopar but same trans and seems to be highly praised in terms of shift quality.
