Hey, i just started getting gear flare again.
I had it before so i got the gearbox flushed and new fluid put it since I heard on here that it helps to fix it.
It fixed it and it was good as new.
I got my subs installed and straight away it started flaring bad again. It flares when it goes into 3rd bad,and a little bit going into 5th.
Why would it start all over again?
Does it mean the gearbox needs to be rebuilt? It was only flushed around 2.500 kms ago, so would flushing it again fix it again?
I just thought it was all the extra weight, it does weight in excess of 250kg that is new to the new..
It is just about to hit 162kms if that helps.

Hope someone can be of help since I am stuck at the moment thinking what else it can be.

If you disconnected the battery when you installed the subs that would be why. The TCM resets itself when the battery is disconnected, and a re-learn procedure needs to be undertaken to alleviate the flaring.

Sidenote, what did you make your sub-box out of? Lead? Dark matter? Is it an armoured subwoofer box? Does your sub have a 200kg magnet? 250kg seems a bit excessive... Did you hide a body in it too? lol

Does it matter that his is a TJ?

How was the gearbox flushed? By a pro mechanic with genuine fluid or at least done at home, according the proper procedure?

While 250kg's extra weight due to a sub (:nuts:) is quite a steep increase for a 1500kg car, I doubt it would cause that much strain on the transmission, unless it was coupled with a continuous heavy foot driving. I've carried more than that weight when I had the 4sp auto in my car and I had no problems. I've gone camping many times for long trips with more weight in the car (boot + 3 good sized blokes) without any transmission problems. I'm wondering if the electrical drain could be causing problems for the TCU (apart of ECU). Does any of the lighting dim when the sub is running ?

I would remove the sub-box out (get a crane or whatever you used to lift such incredibly heavy sub) and see the problem goes away.

Either way - an external transmission cooler should be on the cards. If I didn't convert to manual, I'd have fitted one up as well.

Random question - have you checked the passenger side footwell for any signs of a coolant/water? Sometimes, I've seen cases where the heater core gives way and the coolant leaks onto the ecu, causing transmission shifting issues.

Does it matter that his is a TJ?

The procedure should be the same with all 3rd gen autos (4 and 5 speed). I have done it in my TJ 4-speed without issue.
Someone please correct me if I'm wrong.

My money's on this. Your gearbox will flare like anything once the battery's been disconnected. Happened to me all the time.

Mine was disconnected when the heater was replaced early last week. I did the procedure and its sorted the issue for the most part, still flares from 3rd to 4th under acceleration though, but should sort itself out in time.

Two 12" woofers, box weights around 50+
I tried that procedure thing, had to do it in tip tronic as my car is in fifth at 50. Still flares going into third
It was flushed by Paul wakeling so I don't have a clue if they did it properly. All I know is when they flushed it, it didn't flare anymore so I guessed they did it right.
Anyone know of a good mechanic in Sydney to flush it if it needs doing Gain?

Tiptronic won't do anything for your car. Tiptronic does not make the transmission learn. You need to follow the procedure to a T, and just drive the car quietly until it learns how to shift properly, again.

Yup, like MYKHVERADA said, you need to do it in Drive.

Personally, I've never bothered with the relearning procedure. The worst of the flaring will go away after 2-3 days, and will be completely gone within a week or two.

The hardest thing with the relearn procedure is finding a nice stretch of road where it can be done without interfering with traffic, and without looking stupid stop/starting :)

So I have to be going 55-60 and make it kick down to 2nd?
If I do nothing will it go away by itself or is the relearning a must?

Like I said, just one post above... yes, it will eventually go away by itself...

Have you read the procedure? Read it again. You're not making it kickdown (downshift) from 3rd to 2nd; you are accelerating steadily - from a stop - to cause a upshift from 2nd gear to 3rd gear at 55-60kph, then slowing steadily to a stop. Repeat.

Oh sorry, I didn't understand it.
Thanks for clearing it up :)
