Best Shifter for 700r4

[ssx]

I have a B&M Hammer in my 67' Nova. It has a 4L60e in it, not a 700R4...its hard to explain but the shifter feels "sticky" I'd rather the shifts be a little "notchy"...the shop that did the install tried multiple times to adjust it to shift easier...no luck, I tried after I got it home, re-routed the cable a couple times...still the same. I'm looking to change it out as soon as I find something better...
