Shift Kit

Glad to hear it's working. It's pretty much normal for the 1-2 shift to be firmer than the 2-3. The throttle pressure rod adjustment affects not only shift speed but firmness on both shifts. Do you have it maxed out, or at least real close? If so the only thing left would be to drop the valve body again and install a blocker rod under the accumulator. It'll really firm up the 1-2 shift and help slightly with the 2-3 shift. To firm up the 2-3 shift you will have to drill out the 2-3 port in the valve body spacer plate but before you do that you need to see what ratio shift lever is on the the front band. If it's 3.8 or less you can drill out the port to the max of 3/16". If it's a 4.2 or higher don't go bigger than .150" or it may overlap going into 3rd.

BTW: what did you drill out the 2-3 shift port too? Did the accumulator have 1 spring or 2? Some only have 1 spring on the top of the accumulator (the side against the valve body) while others have one on each side. The ones with 2 springs shift the softest
