When you changed the tranny, you also changed the speedo drive gear
(which is now in the overdrive). Some possibilities to correct the
problem :
1) Find the right speedo drive gear. There's some chance the one from
the old tranny will fit.
2) Find a speedo with the right calibration
3) Many speedo shops (look for "speedometer calibration" in the yellow
pages) can build a ratio adapter. I was recently quoted $60-75.
4) Change the rear end and/or rear tires.

I've heard the J-type solenoid adjustment can be used to smooth the
engagement. Personally, I just de-clutch.
