Hey Thealmeidas!
Yep, there's a good chance some part of the exhaust system has come loose and is rattling at certain RPM's. Start fault-tracing by checking if any part of the exhaust seems loose to come in contact with anything, or if there's any loose clamps or similar parts hanging onto it. Another quite common reason for rattle is that some part of the exhaust manifold, such as a bolt or hose/pipe has loosened (often due to rust and/or corrosion).
Another possibility is that it's somehow related to the transmission (since you mention putting it into gear). If so that would be another subject.
Good luck!

It sounds as if your automatic transmission clutch pack is slipping. You could try changing transmission fluid, but sometimes that may make it worse. You're likely in line for a new transmission. It will continue to get worse until your car will not go at all, or it may only be worse in certain gears, depending on which clutch disk is slipping.

I have a 1994 standered nissan altima... when I turn on the car and rev the engine there's no noise... The minute I put the car in first gear and take off there's a rattling noise that increas


Could be a long list of things.
A mechanic would take a test drive and listen under different conditions.
Causes could include transaxle problems, exhaust rattles, worn motor mounts, even valves in the engine.
The difference in idle and moving is a load on the engine and transaxle and the engine shifting position.

Transmission issues revving up and not going in gear smoothly


I sounds like you may be low on transmission fluid. Its hard to say with the limited information yuo have given. If you put it into drive and the vehicle sits there and you give it gas and the engine revs up and then slowly starts moving, it is a transmission problem. If it is low you may have already done irreversible damage. The problem will get worse very quickly. Check your trans fluid immediately.

Engine knocking


Hi,
Good news is - I don't think you need a new engine.

As there are many moving parts that could create a knocking sound, it usually needs careful inspection to identify where it is from.
I will give a list of some of the causes and remedies. Yours will probably be one of them, but unless I was there - it could be any.

Loose exhaust component (causes rattles and thumps) - replace parts or joints.
Loose Engine mounts - Engine will move about a lot more than normal - Replacement of mounts.
Fraying Belts - causes continual ticking or slapping - Replace belts and check tension.
Timing is off - bad running, lack of power, pre ignition or knocking at low revs. Check timing belt - Replace, Tune engine.
Cracked valve - slight misfire worse at low revs - Replacement valves.
Clutch Problems - Broken spring or loose bolt - Check clutch plate - replace clutch plates.
Older engines - often accompanying smoke -
Broken Piston ring - continual ticking or occasional misfire - Replace Piston rings
Worn Piston bearings - Piston Slap - Replacement of all piston bearings.

Transmission Problems (only heard when in gear or with clutch out) - Broken gear teeth or worn bearings - Replacement of Transmission or rebuild.

Some of these remedies require engine removal and strip down, others are a simpler fix.

the rattling from the cat. is from a plate inside cat. there has been some recalls for this. check with dealer. i had mine replaced twice. As for the engine racing, sounds like clutch or linkage might be bad. take it to a trans shop and have them do a test.
