what is exactly wrong with our trannys that everyone keeps saying to get a shift kit in them and so on....?
Can anyone recommend a good flowing quiet muffler that is reasonably priced? I tow a lot and don't want to much noise in the cab of the truck.

I think most on this board as truck enthusiasts prefer a crisper shifting truck not some boulevard barge shift that you cannot feel. I modified my tranny valve body when I changed the fluid and did the tricumulator mod. This replaces one valve (with a Sonnax) and puts in some stiffer springs. Shifts very quickly and crisply. Further it does not downshift prematurely when pulling a load up a grade. For about $50 it is highly recommended. Look at the bottom of the page here.
As far as the muffler goes, one of the first mods I did was to replace the OEM muffler with a Walker Big Truck Muffler (BTM) 21470 which is 3.5" straight through. Not any louder in the cab but a little louder outside the truck. I got mine for less than $50 and it was $100 at the muffler shop for them to put it in. $100 is high but there was nobody else around who would touch some other vendors muffler other than the one they were pushing so I was over a barrel so to speak. Look here.
