I was thinking of buying a transgo shiftkit for my 89 formula 350 (T74171). Is there a better shiftkit? I was also going to buy the Transgo Performance 7-2P Servo Piston Assembly Corvette and putting a bigger trans cooler on the car. I have never realy messed with the 700r before except filter and fluit changes so any feed back would be nice. The tranny is in great shape buy the way.

yes, go ahead and install all of that, no worries.
TransGo is the best to start with, and I modify them to do even more. I have the boost valves that are needed and the Corvette servo, etc. Go to https://www.700r4l60e.com/store/home.php?cat=65 Call me (909 795-1876) with your setup, and I will match it to what you are using and how you drive. Dana
