In 5th gear only it seems, I am starting to hear a loud tapping from the transmission. I is loudest under hard throttle and when engine braking. Any ideas?

Loud tapping noise from transmission

First check the simple things. The propeller shaft between the t-case and transmission is a good place to start. Then check all the others. I've had several loose ones cause tapping sounds.

I checked it today It seemed fine I will check it again. I would think if it was the shaft it would happen in all gears. But weird stuff happens.

Well 5th gear is the fastest RPM the shaft will spin and the slowest RPM the engine will spin. That's why it's typically easier to hear sounds like that. Another thing to try is to put the t-case in neutral and run the transmission in 5th gear to see if you can replicate the sound again. Process of elimination when it comes to weird sounds...

also when I push in the clutch it goes away. My first thought is the short drive shaft. I will check it again tomorrow.

The shaft was fine. I pulled the top cover off the trans and found one of the 5th gear gears is missing several teeth. That is the same thing that happened to my last trans. Is this a common problem or am I driving it wrong.

My trans only seems to have a synchro on second and third. First will grind, 4th and 5th will grind. I don't even use the clutch anymore on those as they like to be dropped in at a "sweet spot" that I know of. I do know that a normal deuce is able to use the clutch when changing gears so long as the transmission is fine. I wouldn't thing a gear in the transmission would create much a vibration when missing a few teeth. After re-reading that, I once had a Honda 50 small dirt bike. The chain popped off one time and locked down the drivetrain. I suppose it lost a tooth or 2 in first gear. It would tap like crazy in first but in second or third, it was quiet as could be.

I cant feel it at all. But I sure can hear it. I would like to put a different tranny in the truck but as I have read it does not seem to easy. And the trannys that might fit are not OD so that is no good. The only option I have though about is a New Process 540 out of a chevy wrecker I have, but it is non od. The only up side is that it has two places for a pto and I would really like a rear facing pto.

the 3053 trans is very strong and will last for longer than much of the rest of your truck. problem is they are abused by people in the mil, and you can eventually break anything if you try long enough. fix what you have, take care of it, and you will never have another problem with the trans.
