I have a noise that occurs from start and only in first gear that sounds like metal on metal noises. If you hold the truck in 1st you can notice the noise throughout the rpm range. Once it shifts to 2nd, nothing. You would almost think it was a heat shield rattle noise, but I have pretty much ruled that out. Also, in park or neutral, if you rev the engine, no noises whatsoever.

It's also worth noting that this transmission shifts exceptionally well, no slipping, etc. This is a 2000 4.0 SE with only 45K miles. I've read some posts here and there, but couldn't come up with anything.

When was the last time you changed you transmission fluid? Mine made a grinding noise at acceleration, because it had the wrong type of transmission fluid.

I recently bought the rover, so I don't know. It only has 45K, so I wouldn't be surprised if it was either the wrong fluid or just old/contaminated.

A fluid change is first on my list, but I also wanted to get some direction from other owners as I've seen this issue posted elsewhere.

Was yours only making noise in 1st?

Made the noise under acceleration in any gear, but was most noticeable in 1st and 2nd. Have you checked the fluid level? that would be the first thing to check.

Well, I just completed a full transmission and transfer case service including filter. That appears to have solved the issue. Thanks for your help!

A couple of years ago I went to a garage that is knowledgeable about transmissions. They had a computer program like most of them do now days and the computer said that hooking up a rover ( 99 se) to a transmission machine that pumps out all the old and puts in new ATF was NOT RECOMMENED, Any one know about this? :?:

I have heard of this done. Many of my friends do it to their vehicles and do not have a problem, I could not imagine why a 99+ rr would have an issue, but computers don't like .

Well, now I'm hearing that noise again. I'm starting to think it might be planetary gears. Does anyone here have noisy planetaries?
