Transmission Problems

[jack14]

Im at 81k miles and i think the transmission may be on its way out. Under full throttle the car won't let go of first gear and sometimes a little bit in second. I try and pull it from first to second but it holds the shifter in place pretty firmly and then won't go into second. Similar issues up through fourth gear. No grinding but i can pop the car out of gear no problem without the clutch. Synchros? Shifter bushings? What do you guys think? Shifts pretty well under moderate throttle.

Time for transmission service if you never had got that done. Change the trans filter and fluid. That's first step.

Has the clutch ever been replaced?

What is this transmission filter that you speak of on a RS4?

It filters out the people who seem to think RS4's came in Automatic/DSG.

[jaehoppa]

sorry to hear all these problems..i hope everything gets sorted out soon

I LOL'd.

Any clutch work done at any point on this car? Sounds like the clutch may not be disengaging to some degree, causing you to get stuck in gear until you pop it out of the gear(sort of like rev-matching). Could be a pressure plate problem, throw-out bearing issue, or even the dreaded transmission filter problem that 2001 - current RS4s have had(kidding obviously). If it was a collar or synchro problem, I think your issue would be more getting into gear without noticeable grinding, perhaps not so much getting out of gear. Hope this helps to isolate your issue somewhat. Either way, I think you have a transmission drop in your future.

LOL dead.

Clutch was just changed, should have mentioned that. Weird that it only happens at high revs which is why i think that the clutch not disengaging would be the issue. Definitely doesn't go into gear either and first is the only gear i really can't get it out of.

I'm not questionning your driving skills, but is it possible that you try to pull it out out of first gear when still at full throttle ? (big load on gears )

Dude, now you have two threads about your clutch/transmission issues.

Find out if your shop replaced your slave cylinder, if not then have them do that.

If your slave is original with 81k miles and you just upgraded to a pressure plate with 43% more clamping force you are bound to have issues.


Synchro issues usually show symptoms like mmbooost mentions or the car pops out of gears on it's own, they don't usually feel "stuck" in gear.

[daytonars4]

What you are describing is similiar to what I experienced with the first lw clutch and fw I tried. Ended up changing the setup and my problems went away. Considering this and your other thread, I'm going to say it's pretty likely you are in for another transmission pull unfortunately. You can give redline tranmission fluid a shot. You can also certainly first take a shot at the salve cylinder and a flush, but those items didn't work for me. Maybe you'll luck out and they will solve your problems.

This is precisely why I asked the question regarding your clutch being replaced recently. Knowing that you've upgraded your clutch, and not just replaced it, would also make your slave a possible culprit. I think potentially less likely, but a possibility. My money at this point would be on some type of TOB installation issue, or defective TOB of sorts.

I've seen this issue with defective clutches (it happens), but it could also be a failing slave. Which clutch did you replace it with?

Not sure who your normal shop is, but feel free to bring it by if you want us to take a look at it.

[EUROSWAGR]

The problem is he said he had the same symptoms on the OEM clutch in his other thread.

Basically he had pedal issues while OEM
So he upgraded to the 3R
He said the issue is still there but it got a little better?

That tells me something was going bad and didnt get replaced.

[Jake@JHM]

There is a possibility that the pressure plate bolts weren't torqued correctly.

First have the individual who works on your car check the slave/bleed the lines. reference this if needed: http://www.audizine.com/forum/showth...ing-101-by-JHM

If the above doesn't work, pull the trans out and make sure the pressure plate bolts are torqued evenly with red hight-temp loctite.

Alright lets forget the old thread and go off of this post right here. Simplify this a bit. Had an awful dying clutch and it finally disintegrated and was replaced. A new JHM 3R clutch and flywheel were put in. Initially I had similar clutch pedal issues which were described as inconsistent in weight however the clutch has been 100% perfect the past few days. Lets leave that issue alone for a minute. This transmission has 81k miles on it. Complete service records are unknown. What we do know is that we have a fresh clutch which now seems to be doing its job perfectly. The remaining issue is shifting under full throttle. We seem to be hooked up on the car not shifting out of first but thats really not the main problem. The MAIN issue were seeing here is the car not entering into 2nd 3rd and 4th smoothly. A hard shift at WOT out of 1st requires a little extra pull than need be. (Yes i described it as more sever earlier but the problem seems to be less prevalent now for whatever reason). Now that the car is out of first it has to be wiggled and finagled into 2nd gear. Feels kind of like its getting hooked up on a shifter bushing or something. We can't disregard whats going on with first gear but the main problem is entering gears. Also don't forget that this problem is non existent under 5k rpm and much more minimal above 5k at half or so throttle. Now lets discuss further. Mods feel free to close the rough clutch thread.

Maybe your installer messed up the shifter linkage.

Something else to think about is, if the slave is failing and not disengaging the clutch properly..that will also cause your car to not go in the other gears smoothly.

Again, if they didn't replace the slave..you should probably do that. When they do that check the linkage too.

Agreed, if your slave cylinder is original, you should really replace it, it's the most likely culprit here, and eliminating it from the equation will help simplify the process of finding the problem.

Good? Im gonna do a new linkage as well as JHMs short shift kit. If the issue persists after this, well I'm screwed aren't I?

[MMMB00ST_A4]

Slave is a 15-20 minute install. I would do that first, then move to the linkage if the issue persists.

[BenSti]

Not on an RS4, you have to remove the downpipe to swap the slave.

Not necessarily. With the proper arrangement of tools, and removal of the heat shield above and the bolts holding the halfshaft to the bellhousing flange to create a bit more room, it is a relatively easy fix. I'd say 45 minutes to be more accurate. Far less time consuming and less of a hassle than replacing linkages.

[EUROSWAGR]

Jack, do not throw more parts at the car yet.

Replace the slave and go from there. If you add to many possibilities, you'll never figure out what is wrong and you will be screwed.

[Peter1.8t]

^ Agreed change one variable at a time, that the best way to troubleshoot issues.

[jack14]

Problem is its a lot more expensive to go one at a time. Not in a place where i can do my own work on the car and don't want to wait 2 months until I have a garage to do so.

Hmm. Given those restrictions, maybe a 10 year old Audi was not the best choice.
