Name that problem! (I think TC)

**Jimmy** · August 15th, 2012, 19:51

Based on what you've said Brav...I also wager it could be a control module or the valve body....since it shifts OK, then all goes bad, then its OK again.

I've had this thought before:

If you have an mtm or other tcu chip, does it put extra stress on the solenoids and cause them to fail prematurely?

Tozo says that the solenoids rarely fail.

Well for all I know, I am on the original trans. But 2nd TC. I think 160k miles is "fair" life expectancy. I will test the 5th gear pull to see if its my clutch pack "A" and report.

OK- another road test. Got ballsy after driving it around my office and took her home (12 miles). Tried various gear pulls on highway. No issues. My house is in a hilly area so I got a bit nervous. No hiccups all the way home. I got my gym clothes, and as I started to come back, it slipped right away within 1 minute of turning the car back on (this is consistent with how it first happened. quick off, then back on). Then came the hill.. and she behaved. Slipped on and off the rest of the way. Several times I would feel it engage better right after slip, then I would hammer it and it would TAKE OFF! what the hell.. Actually none of the times I did a hard pull, did it screw up. Just sometimes after coming to a stop and trying to go again. Not sure if this sheds any more light.

In tip mode while slipping, it would jump in RPM, then drop into the next gear without telling it to, all the way to 4th.

No codes. No red PRNDS.

If it were a bad clutch pack, wouldnt it consistently slip during a hard pull? My knowledge of auto transmissions leaves a bit to be desired. Still smells like electronic issue to me. Or.. crud stuck in valves?

Good luck but as the former resident tranny replacement king I will say that my second one went just as you are describing from your sister's experience on. Took the TC with it but not sure what exactly failed within as under warranty I did not care back in '05 to ask. It started simple on a trip then progressively worse in 500 miles to barely holding low gears to limp it to dealer. My other ones failed a little differently.

Intermittent problems are the worst. Personally I would think clutch packs vs. electrical. Might be the VB. Certainly not the TC. If you can duplicate the problem you can solve the problem. Try the stall test and see if it jumps out of gear.

Have you done this current driving without getting the fluid checked, are you crazy man?

My mechanic is experienced with other Audi's, and believed my trans was filled after some work, following all instructions. Months later, occasional slip, top gears, heavy load, no codes though, it happened three times. I went in and was 2 quarts low, I think it holds 12 or so with the TC?

**Brav** · August 16th, 2012, 18:24

Ya I'm crazy. No way to check it until I drive it to a friends lift. I highly doubt its low on fluid after so long. But I hate being wrong...

**ttboost** · August 17th, 2012, 21:22

Yeah...I thought I was wrong once...crappy feeling...

A: Your trans leaked 2 quarts

B: Your mechanic didn't fill it right

BRAV,
$300 card, $3000 trany drop to replace card on top of trans, $100 platinum co-pay,
beating to hell thier S4 for two weeks, priceless.

Yes this is what I had.
Why is it I always get the wierd stuff first!
leaking fuel tank, smell gass off and on
Vacuum leak under manifold so brakes go bad,off and on
card on top of trans. wierd trans, again off and on.

**Brav** · August 18th, 2012, 05:51

was the trans control card what cause the problems?

**AUDI5000CSTQ** · August 18th, 2012, 06:04

Too much Dentist's laughing gas, John. There are support groups for that type of thing...

**AUDI5000CSTQ** · August 18th, 2012, 06:19

Sorry, read it as " what caused the problem"
My answer is always, just like, "why does it cost so much?"
Has 'AUDI" writen on it.
A toyota would never have had this problem.
An RS6 owner askes a Toyota owner " want to race?"
Toyota owner answers, " sure, how far?"

**Brav** · August 18th, 2012, 06:57

hittin the sauce, LOL? The question was simply if the control module is the problem leading trans failure..

If I wanted a Toyota, I would get a bowl cut, stock up on mock turtle necks, and divide my personality in half. pay to play..

**kilian tuning** · August 18th, 2012, 10:22

mine is slipping to , but only when i accelerate very slow...about 200-300 rpm rise after gearchange...prob normal...

**AUDI5000CSTQ** · August 18th, 2012, 16:47

It doesn't cause the trans to fail. Just makes it act badly.
Do you have any insurance?
I have lots of cars for different purposes.
