what would cause my car to run fine when it has first started up then after a while first gear will kinda bog down.
Your motorcycle might idle fine and bog out when in gear because of a problem with the carburetor or the bowl. If either area is dirty, it will often bog the bike when in gear.
If it's in the right gear, it sounds like a timing problem.
will the transmission causes my 1999 ford expedition to bog down & sputter when accelerating the 4.6liter engine.
It could be the carb needs to be rebuilt. I have a 1971 f100 myself is a 360 manual 4 speed and that fixed that problem. The accelerator pump on it wasn't working causing it to be way down on power and bog down when I was giving it the gas. If yours is an auto tranny then there could be something wrong with it like its skipping first gear or your torque converter isn't stalling when it should. Hope this helps you tjman oug

The transmission will shift to the appropriate gear, if it's functioning properly. Otherwise, you'll either run really high RPMs, or you'll bog down.
p275-16s are near the limit. You'll have to gear down your front and rear diff, otherwise the big tires will bog you down on the highway.
Does it always bog? Maybe you overfilled the case with oil. Have you tried a new spark plug? maybe your in the wrong gear. -need more info on what it does/when it does bog-
sounds like your only running on one cyl
The first bog body discovered dates back to 1702. It was found in a peat bog in Denmark and is known as the Tollund Man.
The most common reason is that your air/fuel mixture is inefficient or dirty. If your air filter is clogged or has a lot of dirt. It could be bogging down the engine. Consider cleaning the air filter or replacing it with an air kit to see if the problem is resolved.
