I am in the middle of installing my trans go reprogramming kit and came across a couple issues. Which range did you guys go with for your street cars? It will see the strip rarely. Street Rod (Range 2) or Hot Rodm Firm(Range 3). I know I am definitely not going with Range 4 full on comp. Also, I removed the 2-3 piston and a new one wasn't provided, is this normal in these kits?
