I'm swapping in a th350 in my 95 firebird. I have a procharger on this car. The tranny needs vaccum to shift. I have only boost to offer. I was told that they sell something that does away with that part of the tranny. If I'm not mistaken, it uses a cable. I believe the part# is 40M. I found a place that knew the part#, but does'nt sell it or know where i can get it. I need to know where I can buy it and if this is what I'm looking for. I know people have done this swap before. I don't want to manual shift it all the time. Please help. Thanks.
