700R4 Trans Modifications - Required?

[Driver_WT]

I am putting a 700R4 trans in my 53 Chevy Truck (S10 frame, 350 SBC). The 350 SBC will have 350 to 400 lb-ft of torque. My research seems to indicate that this kit will make getting the TV cable adjusted properly easier http://www.bowtieoverdrives.com/cata...php?ITEMID=217

What about the TCI constant pressure valve body kit - is this required or desired? https://www.summitracing.com/search/...ion-type/700r4

Truck will be used for cruising and the odd bit of abuse of the rear tires

I did a search, but could not an answer to this.

Thanks.
