My wife's car has been a pain in the ass since we got it, and I hate to keep bitching about her car but it's a wonder I haven't set it on fire. My car used to be an auto before I installed a five speed in it and I don't ever remember losing boost between shifts. I just had her transmission rebuilt with Raybestos blue clutches and had the valve body rebuilt by IPT. $1640.00 later, it loses boost between every shift. Is this normal? It has a Tial blow off valve on it and no vacuum leaks or boost leaks that I can detect. I haven't checked the transmission codes yet, but I'm going to go outside and check them in a second. I wanted to post this first. I did search for similar problems on here but didn't find any. Thanks, Jay
