automatic 727 modified / shifting issue?

my factory rod with adjuster came with a shorter version of yours so I recently modified it by buying a section of rod from menards and MIG welded a section into the factory rod and gotten rid of the bolt-nut-washer. dont have a photo its been raining here for a few days . it's all properly adjusted but still having the issue of not kicking down to pass while driving Hwy speeds - 65 -70-75 ect. I stomp on the pedal and can here the 4 barrel kick in but no shift ?I'm wondering if it's the racing shift kit ? the 727 was built by a professional and since it's a racing 727 auto I have to run Type F or b&m quick shift fluid . only . thanks for the pics

I’ll say this one more time.:D
Sounds about right for a stock trans not to kick down at those speeds.
The problem with changing it may result in unwanted side affects.
Not saying it can’t be done, just saying in the end you may opt to downshift it manually and live with it.
Or, if you have the funds, time and patience you could start changing things.
Personally I opted for the part throttle kickdown valve assembly be done with it.:D
