This is what I installed in JagZilla when she still had the Turbo400 in her.

I had firm shifts when I wanted them, and soft shifts when I was just cruising. I was also able to upshift and downshift at will, and hold 1st & 2nd gear past redline.

I'm having a hard time finding the shift kit I want.
Why you ask?
Because I want the shifts to be softer, not harder. I want the shifts to be completely unnoticeable. I don't want to feel the transmission shifting at all, just smooth acceleration.
Does such a kit exist?

its called an original Jaguar spec GM400 box
if yours is shifting and your noticing it, then it probably wants a strip and rebuild replacing all bushings and any other worn parts, and all 7 ( yes 7 ) flow ball bearings need to be installed , i have reduced mine to 4 bearings, from memory a minimum of two are required for the box to still work , i also installed the adjustable vacuum , it now hangs on for higher revs for longer ,
in the UK a full strip and refurb at a gearbox socialist will cost £2k , they will also warrantee the box for that
i rebuilt my own ( see thread ) for under £500.....
