7 speed auto with 3.69 differential rpm question

I am looking for someone to post what their rpm drops to between each gear when shifting at approx 7400-7500 rpm.

With 3.35 rear on 26.7" tires my shifts are the following
1st to 2nd drops from 7500 to about 6000
2nd to 3rd drops from 7500 to about 5500
3rd to 4th drops from 7500 to about 5500

Anyone with a stock rear auto can chime in if they want to help verify my rpm drops. I am trying to see how the powerband will be impacted with the gearing change to 3.69. Thanks for any help ahead of time!

With 3.691 rear on 26.9" tires my shifts are around almost the exact same as your's according to the tach. I can try to do data logging to get you exacts, but expect a 10% difference depending on the condition of your tranny getting into gear.

Yeah funny thing is right after I posted this a video came up on my youtube app that showed someone's speedo with the 3.69 gears. Looks like they are exactly the same
