727 2-3 upshift VERY harsh

If they didn’t install a 5.0 lever for the front servo, then that’s part of ur problem. U will need to adjust the front band to 2 1/2 turns from snug with short wrench if u don’t have an inch pound torque wrench. Torque is 72 inch pounds then back off band 2 1/2 turns the tighten lock nut. Kim

My ex partner built our transmissions back in the day, he used to adjust our 727 front band to snug, and back it off 2 turns. I am not a trans man, but I don`t think I`d back the band adjustment off to try to soften the shift for any reason.
On a side note, my currant 727 is fully automatic, and slams the 3 rd gear shift so hard and fast it makes me think its going to break something. I adjusted the aftermarket kickdown looser almost an 1/8', but was afraid to go any further. It helped a small amount, and isn`t bad if I`m accelerating some, but still slams too hard if not accelerating, like in traffic. Will probly be fine at wot .
