1996 a6 front drive auto transmission. engine is revving 4000 rpm at 60 mph on the freeway so I changed the fluid as the Bentley manual says but it still does the same exact thing with the new filter and fluid. By the way I got the fluid and filter as a kit from blauparts.com. The only reason that this concerns me is because I was reading the forum and noticed that people where saying that their cars where revving 3000 rpm at 60 mph. that was the only reason that I changed the fluid other wise it shifts and feels fine. Any help someone could give me would be greatly appreciated.
Re: Is all the transmission settings in the dash display lit? SOunds like your tranny might be in
i dont know what you mean by "transmission settings in the dash display lit" if you mean some sort of warning lights, than therir is nothing. when the trany is in limp mode dose the "OK" in the dash message still light up or would it be repliced by a transmission falt indication. becuase every thing on the dash looks good. during start up i still get the "ok".
When you serviced the transmission did you fill it according to tempurature?
If you're feeling the shifts, then I think it's probably not in "Limp Home" mode. I think in limp home mode it just stays in 3rd all the time (right guys?).
I'm still learning about these transmissions, so I don't know if the torque converter has a lock-up mode for each shift. If it does, you might just be feeling it shift out of first, then go into 2nd unlocked, 2nd locked, 3rd unlocked and then 3 locked. (I could be wrong there though).
If it were getting to 4th gear, you'd be doing 80mph at 3,900rpm...that's what mine does anyway.
You definately don't want to screw around with this though. Get it in and get it properly diagnosed. That transmission would be umpteen thousand to replace.
By the way, did you drain and fill the rear diff in the trans, and check the fluid level in the front diff? Neither will affect shifting but both are critical.
Re: When you serviced the transmission did you fill it according to tempurature?
stays in third all the time!!! then my tyranny cant be in limp mode right. yes did fill according to temp. it was doing this before and after the fluid change.
when a converter changes the engine speed it only changes like 400 rpm and dose not fell like a shift. Correct me if I am wrong. but that is good thinking and I truly know nothing about these cars. it was a free bee and I am starting to regret it.
do you know if any of those problems should put the tyranny in limp mode. have you experienced any of these problems that you listed. you are right I have no choice but to throw down some coin and take it in. i just hate the idea of some one else working on my car. I cant belive that this has never haped to some one on here befor.
First off newbie don't start calling people stuipd on this forum. You're the one asking for
help and it appears that if you don't like what people are telling you, you get offended.
"yes it is going into fourth i can count the shifts. and if it was not going into fourth wouldn't the trany be at alot higher rpms than than 4000 at 60 mph"
If it was in 4th gear then the engine wouldn't be running at 4000 at 60 mph. So there are only two choices left to choose from
1. you are not going 60mph or
2. the engine is not at 4000rpm. If your car was in 4th gear as you believed.
Base on your remarks "if it was not going into fourth wouldn't the trany be at alot higher rpms than than 4000 at 60 mph" what would you calculate the rpm to be?
If it was in 4th gear I calculate that the rpm should be around 2750 at 60mph.
And if you show 4000 rpm and you are in 4th gear then I calculated that your car should be traveling at about 75mph based on 195/65/15 tire.
My 92 100S PRND123 display all lit up and stayed in 1st...
I didn't go outside and look but the display in the instrument cluster that shows you what gear your in will normally light up D if it is in drive, R if it is in reverse, etc. I think it has the characters PRND123. Anyway, from what others are saying, if all of the characters are lit up, then the car is in "Limp Home" mode.
However, last week, I was driving my wife's 100S which is basically the same as my 96 A6. After stopping at a store, I started the car, left the parking lot, and then noticed that the car wouldn't shift out of first gear. It was then that I noticed that all of the characters in the drive display were lit up which I had never seen before. I pulled into a parking lot and tried shifting to reverse, drive, etc. but nothing changed. I could only drive in first or reverse. Then, I turned off the ignition and then started the car again. The display returned to normal and the car drove normally.
I can only guess that some sort of sensor or electrical connection shorted or opened up causing the computer to put the trans into safe mode. I don't know why it was stuck in first since all of the posts mention that the transmission stays in third when in Limp mode. When it happened to me, it was definitly in first.
I don't know if there are any kind of 'latching' OBD codes for the tranny that won't go away unless you clear the codes. It might be possible that the OBD detected a problem and put the tranny in Limp mode. My A6 gets a latching EGR error if I drive the car at high speeds for over 8 hours. There is nothing wrong with the EGR valve, there is just some sensor somewhere that thinks there is. The latching code for the EGR valve causes the Check Engine light to stay on until it is reset.
I think that some auto parts supply houses will check codes but I don't know if they will clear them. I think Autozone is one of them.
You might be able to resolve the problem as easily as clearing the code if there is one.
I can see you being mad about a car you purchased being unreliable, that would make anyone mad; but complaining about a car that was free seems pretty shallow.
What I meant was even if you have to put $500 (estimate) into the car to get it going its still only a $500 car. People on here have actually paid money for cars knowing they were going to have to perform work on them and complained less.
There is a lot of people here who can help you, but first you need to learn how
your car works. Take notes, read the manual ( you need to know where the transmission display is).If you don't describe your problem accurate, we can't help you.
