2009 V. I've been trying to quicken the 3-4 shift. As it is, it is 0.6 seconds long at WOT, and the timing barely drops for it. I will attach a scan file and my tune. Look at timestamps 346 and 708 for 3-4 shift points at WOT. I've tried a number of things, including the 2010 mod file trans changes for shift times and pressure times, but it doesn't seem to change it. I haven't changed everything from that 2010 mod file, but I matched the things that I thought would affect it. My tune file is also attached.
Can you provide some guideance on how to properly shorten the 3-4 shift and to firm it up? Your help is much appreciated.
Thanks!
