Default Modified my automatic shifter

I've never liked the distance you have to push the button for downshifting. Too awkward and not ergonomically friendly for precise, deft shifting. So today while I was in there verifying a sticky shift cable, I thought I'd just go ahead and remove it and see what could be done. It would have been easy enough to remove the lock altogether, problem solved! Not quite, no reverse lock out that way, NOT a good thing. Having once put a big block Cuda into reverse in the traps at 110 or so, I don't really care to experience that phenomena again. So I decided to cut the size of the step that the lock works against in half. And while I was at it, I even ground in a step to be able to downshift to second w/o overshooting and going down to first. Be forewarned though, this metal is hard. Without a die grinder and a small flat stone on the Dremel to finish it off, it'd have been nearly impossble. What minimal filing and sanding it needed was somewhat time consumming. These steps must be precise and smooth (in their gate) and allow for the shifter to "float" a bit in any given gear so the cable and shifter can always allow the transmission lever to find it's detent and be positively in the gear. Otherwise, transmission damage could occur. Just thought I'd pass this along. I think this will help with auto-Xing an automatic. I'll know in a few weeks. Oh, if anyone has the cable part number handy, I'd appreciate it. I have a thread for that too, thanks.

My '88 didn't have detents below 3rd gear so I bought a used shifter and, similar to you, cut steps into the gate.

Now I can drop from 4th to 3rd by just pulling the shifter back but must depress the button to get to 2nd or 1st. And on the up shift, there is shift feel at each indent, which was absent with the stock shifter.

I agree the gate is really tough metal. I burned through several cutoff wheels on my Dremel before the job was completed.
