Do you have other locomotives that work fine with your TMCC equipment?

Well, the fact that it takes off when you're attempting command mode, and you can't program it, I suspect you have an issue with either the antenna connection (handrails) or the RCDR TMCC receiver.  The RCDR is not available, so hope it's an antenna issue.

Yes my Legacy 0-6-0 connected up, but it was a bit finicky to get it to connect aswell but I eventually got it to work.

It was only taking off here at home so may be just my 40” piece of track on the floor. I could put it in program mode at the train store and it stayed in neutral but still taking my Cab 1 setup up there wouldn’t acknowledge the remote. Also in program mode shouldn’t the engine not fire up with sounds? Or does it fire up with sounds. I know when I programmed my new Legacy 0-6-0 it was silent in program mode till the whistle blew when I added it.
I’m hoping for an antennae issue aswell but we will see. I ended up having him take it to his Lionel repairmen so we shall see.

You're throwing different symptoms around rather loosely, and changing environments as well.  It's very difficult to keep up with all the twists and turns.

You need to clearly define an environment and then do some diagnostics to start narrowing down possibilities.

Hard to do when I currently don't have a physical layout at the moment which is currently under construction. I am just working with my test track section. Only reason it went up to the store was because I was told by someone else to try it in conventional mode and I don't currently have a way to test conventional and the store did.

There shouldn't be anything "finicky" when programming.

You slide the run/pgm switch to pgm, power up the track and push ENG 18 set. The whistle will blow and you'll get idle steam sounds.

( I'm using 18 as an example, it can be whatever number you choose. Most people use the first 2 or Last 2 digits on the cab)

Then remove power and slide the run/pgm switch to run. Power up the track and address the loco. I.E. ENG 18, and it should operate as designed from the remote.
