1st Gear Issues

[oldblu]

Ok, I replaced my tranny fluid with Redline MTL in about January. When the weather warmed up, I started to put my windows down and heard this strange noise everytime the clutch was released and I had the car in fist gear... It sounds kinda like an old Mercedes Diesel car from the eighties and it only happens in first gear - everytime. Now I replaced my fluid with Audi's 75-90 but the noise is still there. What could it be??

[djwimbo]

Does it only do it under light accel?
Do it turning, low RPM's, any more info.

My boss chimed in and said it's a tranny issue and Jeeps do it a lot. I don't want to jump to conclusions, but it's possible.

[oldblu]

I think it may be tranny too.. No, turning is not a factor, neither is rpm. Only that when it's fully in gear, it sounds really bad. But why is it only 1st gear?? And what kind of fix is this?

[Dietbudda]

you don't have a LWFW do you? mine chetters like a diesel.

Also, how old was your tranny fluid? alot of manufactures and repair facilities won't replace fluid if it's over 75K due to the oil being the thing holding the trans together
When you drain out that old fluid and put the new, thinner, less gungky fluid in, it makes parts move eaiser, allowing you to hear things you shouldn't have before.

At the place i used to work at we did a drain and fill on a ford with 67,XXXK on the clock and the second we started it up, it sounded like the gears were loose. put the old fluid in, no where near as bad.

just an idea for ya

[oldblu]

No LWFW and the Redline I put in in January while I just put NEW dealer fluid last night. I'm pretty sure Audi's are known to have very dependable Trans

Ask the 4th tranmission i've had in 8 months if they are dependable.

[oldblu]

lol I'm sorry to hear that but I'm hoping that it's just bad luck...

Sounds like something else in your setup is killing transmissions...

Explain to me how new oil is "thinner" than used oil.

Why does it seem that I'm the only one that doesn't have that? I know I went with the 16lb FW to avoid it, but some people get it, and others don't

I'm not sure I agree with that second part. #1 you should replace the every 30K, and #2 if it's been in there for 75K it should be replaced.
When I changed the gear lube in my Camaro's axle half came out like water, and the other half came out like hair gel. I talked to the previous owner and he said it had been 7-8yrs since it had been changed.
Basically the tiny little bits of metal that are worn off of the gears, blocking rings, dog teeth, keys, synchros, etc are all suspended in the fluid. When that fluid comes in contact with bearing surfaces and other hard parts it can work like liquid sand paper. That's a bad thing.

Audi Tranny's are dependable. IIRC Mike is running a stock-ish 1.8T trans, if that makes a difference. They're a hell of a lot better than DSM Trannys. I know that for a fact.

Basically what it sounds like you're hearing is the gears "ratcheting" inside the trans. They're essentially vibrating in the space the gear oil is supposed to take up or dampen. It may be that there's an excessive amount of clearance, but w/o taking it apart there's no way to tell for sure.

[4A Play]

I have the same exact problem. I have been told its a cracked/ chipped 1st gear.

[oldblu]

ooh... What would this cost to fix? Is it worth fixing or swapping?

[A4mative Action]

Im having a simallar problem with my avant first it started to my alot of cluncking and grinding noise every now and them. But progressively got worse just driving in every gear. Then one day it made a sh*t ton of noise turned home and keep spitting out first gear but the other gears would work put still have all that noise. So i got a used trany for LKQ for 600 with 50,000 miles on it. Also got a South Bend Stage 2 clutch. But depends on where u got for labor so places cost a grand or some places cost 700 to 800. Im getting mine done for cheap cause i kno the guy.

[oldblu]

Interesting. What did they say was the problem with it? And is the new tranny working alright?

[A4mative Action]

Notting is in yet cause i just got my 034 street densty trans mounts today. But when i was talking to the guy and told him my problem he said it sound like syncros are bad whice i figured so. But be for that i replaced my VSS sensor and i looked at the sensor when i took it out and in the fluid that was on the sensor was some metal flakes from it. But im putting it in the shop ether tomarrow or next week so ill let u kno how it gose.

Good Luck

What ended up happening? I am looking to buy an A4 and it has this same problem and I am debating on if I should buy it or not.

Let me know,

[oldblu]

Turns out it's a tranny bearing. I need a new transmission :( I'll drive it till I either have enough money for a used tranny+clutch or til it just dies on me

[GetAwayFromMe]

SEEMS LIKE ALOT OF 2.8 TRANNYS DO THIS. I bought my car with this problem and been driving it since. It really wont hurt anything else and you can drive it like that forever. Someone above said that it's a chiped 1st gear and he is right.

[amd is the best]

I wonder if you can pull it apart and fix the chip or just replace the 1st gear? I plan on rebuilding my S4's 6 speed soon, it may not be too much different from that.

[GetAwayFromMe]

I'll be doing it in a month or so. I think it's common 2.8 tranny problem.

[oldblu]

is it better to drop the tranny and fix it or replace the trans?

[amd is the best]

is it better to drop the tranny and fix it or replace the trans?

I would say that fixing it is better, because you may be swapping in an other bad or soon to be bad trans. If you fix it with a new part you know its brand new. Just my opinion.

Good point, so where do you buy just some of the gears from?
About how long would it take to complete the repair (including taking the transmission out and putting it back in)?

[DuviVr6]

I used to have a 97 2.8 and it did the same thing only in first so i would just shift very early out of 1st and good i bough it like that and sole it like that and the car is still doing good

my buddies 99 2.8 does the same thing to no problem either just the sound

[oldblu]

what would I have to fix to rid that sound? lol replace what? and where do I find internal trans parts?
