The car was driving just fine,no shifting issues,no problems at all before getting to work. Then I got back in it after work and put it in 1st and went to 1500rpm and it made a rattling noise in the front left axel area, checked it and it was fine. Tryed to drive it again and couldn't move it at all. Turned it off and let it sit for 10min and it drove but drove like sh*t. Parked it and then the next day I tryed to drive it again and it whines real LOUD from the transmission in every gear but I can't go past 2k rpm in 1st gear without it poping out if gear everytime. But I can go into 2nd,3rd, I hate to put it into 4th, 5th is extremely dangerous to put in... I'm so confused, it was driving just fine before work then I come out to junk!. I don't mind taking anything apart but I don't wanna waste time doing something not needed.
Also it starts up just fine and I hear no rattling anywhere while at idle.

I put a new fx400 6puck clutch in it and it has 945 miles on it.

It sounds like you have a number of issues, a bad transmission will rarely if ever stop the motor from revving. Is the CEL on and have you checked it for code? What car is this?

No CEL, I'm Srry my car is a 98 Audi a4 1.8tqm.

I don't know about the noise a defective coil can cause the lack of revving & missing and many tuners code out missing so you can have a coil pack it in and not get a flashing CEL or any stored codes. Pull the engine cover and make sure the wiring to the coil packs is good and the older cars have a control module for the ignition if I am not mistaken and these line to fail as well. You can run the test in the manual on the coils and control module to make sure they are working properly which is fairly easy.

my first transmission went out like this. parked it, with no problems, started it later and first gear was out, followed by 2 and 3 after 10 mins of driving. although i had a gt3071 on mine, i cant imagine a k04 would destroy it like that

I'm BT know, I've got 1k miles on the entire setup. BUT I haven't been able to do any type of launches or anything just daily drove it.

Sorry, it wasn't really clear until I re-read and saw the part about it popping out of gear so I would say transmission. Usually it will pop out of gear if there is too much slop such as worn bearings or bad syncros so I would try draining the transmission and see what comes out. Check the level first to see how close it is and then drain it and look to see what comes out with the fluid. You don't hear of many that work great when parked and then have problems on the next start up but there is a first for everything. Because it is popping out of gear I would say the clutch is fine as long as it is not slipping the issue is internal to the transmission. Unless you pull it apart you won't know where the problem and it is hard to say whether it is worth even changing the gear oil at the point but there is always a chance if crap doesn't pour out when you drain the fluid.

^Ill do that bright and early in the morning I'm hoping for worst case of a bad trans so I have to get it rebuilt... Is there a place to buy upgraded syncros? Or anything upgraded on the internal of the trans?

welcome to first world a4 problems. dont bother rebuilding it, just get a new one with as low miles as possible. a 01E is your best bet, but of course they arent cheap. i went through 3 trannys in mine, none of which even broke from launching. try to find a 6 speed b6 a4 tranny if you can, or the tranny from a 3.0 b6 a4.

jovak0423
02-18-2013, 02:14 PM
Yea I'm not worried about the problems I can fix anything I'm trying to figure this out as easy as possible. I was also gonna ask if i could do a 6spd. To have it checked out it'll be 400$(take it apart and put it back together) parts are extra, not bad so if I spend 1300 on a rebuilt tranny I'm happy with that instead of pulling it out every 2 months to get a new one. So ill find out in a few days.

colony7
02-18-2013, 02:18 PM
what im saying is, no company makes UPGRADED gears for these trannys. when you have power, they cant take it. itll be a waste of money to simply have it rebuilt with factory stuff. i found a local tranny for mine with 40k miles on it for $200 back when i blew my first one. that tranny, even with low miles off a STOCK 01 a4, only lasted about 10k more miles. you could spend that 1300 on most of an s4 swap, then never have to worry about it again. since your a4 is older though, youd need the entire drive train. a 6 speed from a b6 though however bolts right up, job done.

So a a4 b6 6 speed transmission mounts are a direct bolt up to the car, so the drive shaft/rear diff all bolt up like stock?

colony7
02-18-2013, 04:20 PM
correct. its not so easy for a 01E tranny though. those b6 6 speeds are extremely hard to find though, good luck

you could pull the pan after draining the pan. there is a magnet that should catch most of the metal if there is any. and if not you can just seal it back up with some high temp RTV like right stuff.

There is no pan on the standard transmission.

Advanced automotion sells some great rebuilt/upgraded 01e's.

The rebuilt units they have I believe have shot peened, cryo treated first and second gears as well as the mainshaft.

Also has upgraded collars and syncros.


Also, if you are just revving the engine in neutral how does it respond?

You mentioned a rattling noise by the left front axle, are you sure your cv joint did not come apart?

I have had two fwd a4s that have had the inner joint come apart under load.
The first instance the joint did not completely come apart and I was able to limp it back to the garage(albeit very slowly), not recommending doing this as it can damage the transmission.

The second instance it completely came apart and the car popped out of gear and obviously would not move forward any longer. Also with engagement of the clutch it made quite a bit of noise.

Great info thanks^
I found a trans from a 2.8 with 120k for 300$ nothing's wrong with it... Will it bolt right up? How about the rear diff? I read this info before but I don't have time to look stuff up I think it bolts up but 5th gear is a low gear so better gas milage?

yes, its a direct bolt up http://www.audiforums.com/forum/b5-models-69/2-8l-trans-1-8t-150813/page2/

also, i didnt think of this earlier, but does your car make the noise with the tranny in nuetral? porbably yes, but does it make it if you put the clutch in?

Here's a video of my car I just took, you can hear the whining when it's around 3krpm. I took the video because just incase someone has the sane sound or problems they know what it sounds like. http://youtu.be/_agknemTU78

colony7
02-20-2013, 01:36 PM
well, for starters it sounds like you have one hell of a misfire, atleast at first start. it doesnt sound like any blown tranny ive ever heard, but if you cant get it into 2nd then theres obviously something wrong with it. either a bent fork or something

We do not have enough information to tell exactly what it is.

Before replacing the trans:

Try bleeding the clutch
To eliminate the linkage disconnect it from the trans, can you manually move the selector shaft?

Depending on the results from above the next step is to remove the trans.

either way, if he can put it in first, and all other gears, the clutch isnt the problem. and since he CAn put it in first, the linkage isnt binded to the left, and when you put it into first, its pulling the selector back, so there shouldnt be anything stopping it from moving forward in to 2nd. he's BT, if its anything other than rounded teeth ill be suprised. mine were so round it looked like thry went through a pass on the lathe

I am sure you are correct.

My reasoning was it would only take 30-60 minutes to do those things, and then you know beyond a reasonable doubt it is the gearbox.

Again, I am certain you are correct. [wrench]

I jacked the car in the air really high so I could get a clear look at everything, I checked the linkage again(nice and tight), I had the car off and tryed to go they the gears 1st was ok, 2nd no way!,3,4,5 ok not smooth but ok. I checked the fluid again and nice and full. So I already bought the 2.8 trans and a new clutch fork. So tomorrow morning the trans will be out and ill post wat I found out.
I also talked to Aptuning(vw/Audi specialist) they have never heard of our cars transmissions whining... So I'm different I guess lol ill post up once I figure it out.

02-22-2013, 12:53 PM
dont ever go to aptuning, those guys are a fucking joke. i bought my audi from one of the mechanics there, and when i test drove it the fucking thing was shaking like crazy. he told me the driveshaft needed replaced, and that would fix it. the fucking thing was missfiring on all 4 cylinders, it just needed new coils. dumbasses dont even know what a misfire is. all i ever used them for was buying parts so i didnt have to wait on the mail

That's wat I also do is get parts from them so I don't gotta wait for shipping, I'm like 5 blocks from them. They seem like they wat there doing. All I know is the parts are good and they usually have everything In stock

02-22-2013, 01:21 PM
ehh, i wouldnt have ever let them work on my car. they all act like know it alls, and if you correct them, they just make shit up. i think the most knowlegable one is the cashier, i cant think of his name right now. the bigger guy

Ok!!!! I took of the transmission and everything seemed to be ok so I starred at it for a good 10 min trying to figure out if something I'm not seeing, so then I went to the clutch and looked around and it seemed fine. So I put my fingers in the center of the clutch and wat the f*** do I feel?? My pilot bearing is just laying in there!!! Yea I was playing with it,just twearling it around, the pressure plate was nice a tight it was just the pilot bearing. Now I'm stumped how do I make that stay in there and not come out again? FYI my car was an automatic I swapped it out to a 5spd..... It only have 900 miles on it.

Nvm I found out that wen I took out the trans it may have fell out with it so it maybe just a bad trans idk yet

If the transmission has failed internally you wont see anything until you take it apart...

Is that worth the time?

Is wat worth time? Is taking apart the trans worth the time? Well ill take the experience. Or is changing the trans worth it? I am just about done and I have about 3 hrs into it and I've got 2 hrs left till its all bolted up and driving. I think it's well worth it, so idk I guess I'm defferent then most ppl. I like saving money and earning knowledge over anything. But I'm deffently going to put the 2.8 trans in if this one fails too. I think it's a good and snart upgrade.

I wanted to mention something that is weird between trans missions. I turned the shaft with my hand to see if they felt the same and (the 1.8 trans) it felt like there was a rubbing on the shaft while I was turning it, it just didn't feel right. The 2.8 trans felt nice smooth no rubbing

Of course its worth the time to put your new one in!

I understand I'm just curious to see if I can Pull it apart. How much could I sell my old trans for, knowing that it's bad? 100 bucks? I'd rather not waste my time with all that waiting and just take it apart and see what's inside. I'm curious.
