Would the term "flare" apply to the 2/3 shift where the transmission hunts for third gear a couple of times before actually engaging?

If so, might the K1 spring kit help? (Anyone have the instructions and pics? Lots of hits in the archives, but none of the links to the graphics are working. I have absolutely no transmission work experience, so I'd like to have a look before I decide whether to open it up.)

Thanks to all,

Charlie
