Re: 5.3 into 72
Took the truck out on its first drive today. All seems fine except the trains starts out in 3rd gear and not first. I still have to troubleshoot this as its a bit of a headache

Re: 5.3 into 72
I ended up mailing BP my ECM and TCM today. I tried to pull codes with a scan tool today and the scanner powers up but wouldn't link. Bill said the TCM is the first link up for the scan tool and he seems to think the place that sold me the setup may have just sent a non matching TCM. I hope this is the case. I had constant and switched power at the TCM connector.

Re: 5.3 into 72
What fuse/ relay center did you use.? On my 2005 5.3 , I used under hood fuse box for connecting stock harness. Unfortunately the tranny got its power from the interior fuse center on that model truck. Found out the hard way it wouldn't shift. Did some digging to find that out. God luck. Jim

Re: 5.3 into 72
Have a small update. I may have my issue figured out. There was a communication wire from the ECM into the TCM that wasn't making contact to the TCM. Just waiting to get it all hooked back up to test it. Then it's just a matter of having my exhaust system built and she should be road worthy. I have plans to take her to the rod run in gatlinburg tn this September.

Re: 5.3 into 72
Well, the communication wire was the issue. I got it all back together tonight and the trans has 1st gear now.

Re: 5.3 into 72
The connector on the tcm wasn't making contact. The connector backed out of the harness just enough so there was no contact.
On another note I just set up an appointment for my exhaust to be run. I'm going with 2 1/2" with an X pipe, spin tech mufflers and turn downs right at the rear bumper. |

Re: 5.3 into 72
I have a 6.0 in my 72. I built it to drive it. With that in mind, I'm on my 3rd set of mufflers. I found the Dynomax VT mufflers to have the period correct sound with no drown at highway speeds. Turbo mufflers and Flowmaster 40s were great as long as I kept it under 60. The flow's sounded great, but made my ears bleed at hwy speeds.
I'm using the 2 1/2" kit exhaust from Summit. Tail pipes angles behind the wheels. Good Luck, Jaime

Re: 5.3 into 72
I was going to use flowmaster 40's, but I decided I wanted something a little different. I went with spin tech as I like chambered mufflers.

Re: 5.3 into 72
Well, I have most things tightened up now and the truck is at the shop for exhaust. I had a p0300 code last night and after some troubleshooting found out I had two bad injectors. Once I pick the truck up I'm gonna run some fuel system cleaner through it just to make sure my other injectors are up to par. It will be nice to finally be able to drive her again.

Re: 5.3 into 72
I like the sound of the spin techs. I ordered them from Maryland speed and they didn't give a series, just a 9x12 measurement. They are tame at idle, but wake up at full throttle. I am happy with them.

Re: 5.3 into 72
I've seen a couple of 67-72s on post, but I haven't met them and don't know if they have LS's.

Re: 5.3 into 72
There were a couple small coolant leaks and the first trans cooler I had on wasn't up to par. That stuff seems to be worked out now though.

Re: 5.3 into 72
I've never attempted to post a video. So here's my first attempt at it. A quick exhaust sound clip
