I have a 2004 jeep wrangler with a manual trans rattle in nutral

either solenoid is not holding or transfer case is not engaging completely..also check transmission fluid level.. if low..fill to full..

po733- gear 3 ratio incorrect
this is how to fix. You can try replacing the shift solenoids inside the transmission as long as the trans fluid is nice and clean looking it will be nice red color . If the trans fluid is dark or burnt looking , it maybe time for a new ******

is the transfercase in nuetral ? check that as that is the only thing that could stop a manual trans from moving trk unless the output shaft in trans broke but that only you will know.

The above is just an example found on Ebay, $399

Rember when you press the clutch in, the pressure plate releices the clutch disc and input shaft in the transmission. If you still have noise, It can only be either a broken spring on the pressure plate or the throw out berring. Neither can be serviced. There is a fill plug on the side, It takes ATF

A rattling noise from the transmission is never a normal condition no matter what anyone says, and the first thing to do is to check the transmission fluid level, but it sounds to me like the throw-out/release bearing is riding the clutch pressure plate, and when the clutch pedal is in the up position the throw-out/release bearing and the clutch pressure plate should not be touching each other, and the only time that they should make contact is to release the clutch disk in order to shift the transmission into gear. There should be about 1 to 2 inches of free play in the clutch pedal, and the clutch should start to grab within 1 to 2 inches of letting the clutch pedal up off of the floor, and if this is not the case you might need to have the clutch properly adjusted especially if the clutch does not start to grab until the clutch pedal is half way up from the floor. Also, the main bearing in the transmission could be going out due to low fluid, or a damaged pilot bearing that is allowing the transmission input shaft to wobble just enough to cause a rattle from the main bearing or even a vibration in the transmission.

did you change the transmission fluid

synchronizers are going bad a used trans would be cheaper than a rebuild due to the labor involved

That transmission drum is gone, no other alternative to dismantle and repair.

Hello grega1967, your Jeep Wrangler came from the factory with gear oil in the axles and manual transmission, but the transfer case uses transmission fluid. It is a NP231 and your axles are Dana 30 in the front and Dana 35 in the rear. They should have a 4.10 gear ratio due to you having a 2.5 liter 4 cylinder.

I hope this helps,
