Solve this argument about a torqueflite 727
So my dad and I are rebuilding a 69 Cuda. It has a 360 bored to a 410 with a 727.
He's trying to tell me you cannot drive the car around in drive, you must shift to first 2nd then d, at every stop. Is this true? I have knowledge about autos and how they work, but this is before my time.
The only reason I can think of it being that way is if D is just 3rd.
So who's right internet people? Just throw it in drive and leave it, or always start by sweeping through the gears

Kind of depends on how you built the transmission ?

If the trans has a manual valvebody only using 3rd will be hard on the converter forcing it to slip and building heat.

Doubt if your "bored" it to 410, you probably stroked (and bored) it.
If the trans has a manual valve body (and therefore a reverse shift pattern, P, R, N, 1, 2, 3, and won't shift on it's own), no, you should not down shift while moving, except possibly at VERY low speed. As Iowan said, driving in 3rd/D with a manual valve body will stress the converter, but if you do it once in while, it's not the end of the world. Just don't make a habit of it. When stuck in moderate traffic (very slow moving, but not stopped), I'll keep mine in 2nd gear. If it's stop and go, then 1st.
If it's a std valve body, (P, R, N, 3, 2, 1 and will shift on it's own), leave it in 3rd and have run.

Thanks for the replies. You are correct it is stroked and bored. Just didn't post full details.
As soon as the first replier said manual valve body it all came back to me. I had a major brain **** on that one. Thanks for proving me wrong ;p. I'd rather be wrong then damage stuff to prove a point lol.
