it actually is a little late, Iused the brake cleaner on the lines only, I have a new converter:My drag car is sponsored by a converter company and they give me whatever I need in the way of converters as well as doing all the manual labor part of the tranny swap, they did swap in about an hour and I changed fluid cleaned lines, changed harness and refilled it, they test converters in my drag car to see what they can get from different sized converters and from different trannys---my car had a c-6 then it had a TH-400 then it finally got a powerglide so they have been testing quite a bit. I am in the process of selling the car(have buyer already) and will be turning to a newer bodystyle to generate more sponsors.(nobody wants to sponsor a dated bodystyle unless its a classic) I am also thinking about going into SCCA racing (my first Love) because Drag racing is getting tooo boring. but anyways the 1-2 is late and the 2-3 is also a little late both at WOT. and yes I did detatch the cooler lines to blow them out. I found a piece of metal in return line but instead of using the radiator cooler now I'm using a fluidyne and a B&M cooler-I autocross this car and theres no shortage of heat for tranny.also I live in florida where its not hard to get tranny up to operating temp.but I'm purchasing a chip burner and the equipment asssociated So I can stat burning the chips I need to correct this conversion and to allow me to correct for my ever-changing combinations.350 for a chip every couple of months get expensive.
