What is normal trans operation like?
Hello, forgive me for such a generic question, but this is my first 4R100, my first 7.3, and my first truck with an auto. So, I have some questions.
First, what speed will this transmission shift into OD? It seems like mine flat out won't do it under 45mph. If I'm cruising around that speed, it will act like it 'wants' to but it won't actually kick up untill I pass 45mph.
Also, in what gears will the TC lock? It seems like sometimes it like to coast, and other times it will be locked and I can't quite figure it out. I'm so used to driving a standard transmission that this TC lock/unlock thing is weird to me. Its especially weird to be coasting at 30 mph with the engine idleing and then go to get back on it and watch/hear the rpms have to 'catch back up' to the driveline.
One last thing, how accurate is the trans temp indicator on the factory dash. I understand that its nowhere near as acurate as an aftermarket gauge (i mean it doesnt even have numbers) but in general if it never excedes half way up on the scale, am I still safe?
Are there any major signs or clues that this transmission might be failing, or anything to watch out for that would be a sign? The fluid is a good color and smells like good clean trans fluid.
I can't imagine we'd be welcome at hooters very long if there was a bunch of half drunk guys in the back sitting around whistling and humming trying to make the perfect 7.3 turbo noise...
