ERROR CODE - Engine/Transmission problems - Help?

Postby Trouble » Sun Aug 30, 2015 6:39 pm

Hey all,

Just got my car modded up to a evo x turbo from a ralliart turbo - also got the transmission oil changed plus super sport flash + tune

Had no issues for the first week or so

Then it started having some issues in the mornings on cold starts - first couple gear changes were really clunky and would rev high between 1-2 and 2-3 - couple little pops and random things happening too

Then i was driving the other day and it basically wigged out and spat out an error code - then wouldnt change into even gears only wanted to do 1, 3 and 5

Took it to sam's and he read the error code as P1833: Shift Solenoid 1 short (further research says: Shift Fork position sensor 4 system (Output range out))


I was just reading this thread (http://clubcj.net/viewtopic.php?t=15278 ... 33&start=0) and someone wrote that changing the transmission oil after it hadnt been changed in ages can actually do more damage than good

I had the car from 120k-130k the guy before had it up till 120k and for some reason they dont mark in what they changed when in the log book just that it happened

I had mitsu official service centre do my 120k major service so I thought everything should be sweet

Anyway sam has mentioned he think it could be a mechatronics unit failure - does anyone have any insight before i go spending $1000s on something - i just spent so much on the car and now its not even working properly so i cant spend any more unecessary $

PLEASE HELP!! :(

Sorry to hear about this.
I think you might have to bite the bullet on this one.

unfortunately the fluid is only changed at the 95,000kms as per Mitsubishi standards.
which most on here can agree is far too late.

im going to assume warranty is out the window?

At a 120,000kms they don't touch the transmission at all.
A completed service doesn't guarantee that the vehicle is healthy either just that the maintenance was allegedly done.

There are not that many specialist transmission shops out there that deal with these kinds of units. they are very expensive and still quite exotic compared to the regular slushboxes out there. A lot of shops would be reluctant to dive deep into the internals of the unit.

This really sucks because your looking at quite a lot of money for new parts + labor + new fluid. and then changing the fluid and filter religiously every 45,000 or earlier depending on how hard its driven...

these performance transmissions are not cheap.

Yes this is what i've been fearing

The service manual says its needs an entire new transmission but im trying to find if theres a cheaper way

As i mentioned when the error is up it wont shift 2,4,6

However when the car hasnt been driven for a while it shifts 1,2,3,4,5,6 no problems - drove it tonight without a problem

Then whilst going around a roundabout it seemed to pop up again whilst in 5th gear

So does anyone have any clue what i need to sort of look into besides replacing the entire gearbox?

From my understanding from reading other threads/info - basically the fluid hadnt been changed in a LONG time and had grown thick/gluggy - and now that its freshly changed its thinner and heats up easier and picks up all the loose metal pieces - which is in turn affecting the forks some how?

As if it was actually screwed shouldnt it not work at all? It seems to work fine temporarily but then just goes haywire when the error message comes up again

You mentioned places that know these SST are rare - surely there would be one in sydney?

Holy crap, what a thing to have happen. That really sucks.

Good luck with it - I hope you get the SST sorted out.

Mitsubishi head office believes there are zero serviceable components inside the SST.

There is only one way really to find out. and that is to crack it open and start troubleshooting.
you try could getting someone to reprogram the unit back into a learn mode whilst clearing the codes.

the logic behind this is that the new fluid would be more viscous than fluid that has been cooked for 120,000 kms +.
Most modern TCU\'s take into account aging fluid and adjust pressures within the unit (hydraulic pressure is basically what drives the actual unit.)
other than that your options are either to pay someone who has the knowledge and experience to troubleshoot or rip, replace or rebuild.

all of which cost $$$$.

P1833 is only one of two things.

1) The magnet has come off shift fork 4 or is loose on the end of it and wobbling around.

2) the Mech unit is failing.

So in regards to both the only real way to diagnose is to pull the mech unit out and look through the holes. Then stick a screwdriver in there and latch on to the shift fork 4 magnet. If it is loose it will wobble around and that is your problem. If it's not loose then the mech unit is your problem.

Either way its not cheap but it's fixable.

Just a heads up I'm speaking from experience as I'm in the same boat. My car has been off the road since Jan this year.

I've been waiting for this fix to be developed and it's just about there.

Get in touch with MNA in South Australia and speak to Damien. He will be able to sort you out with a fork when they are available.

Not good to hear at all!

Perhaps speak to some tuners, they should be able to point you in the right direction.

Thanks for that - I hit up Adam from Beeble a facebook message and he mentioned Dodson as well

I think definitely purchase this when its ready and just need to find someone in SYD who is confident with taking apart the unit

Just such a fuck around since i only just spent all my money upgrading my car haha :(

Hopefully its the fork and not the mech unit - since it can actually change gears 1,2,3,4,5,6 fine but only for a limited amount of time - then it just errors up and is 1,3,5

Does this make you lean one way or the other?

I think you're spot on re: the pressure - I unfortunately dont think the driver before me replaced the fluid - so the pressure wouldve built up quite high

Semi regretting changing it - i thought i was doing it a favour since i had all these new parts going in :(

u too Jarryd, not good :(
good luck guys.

i guess if its the mechatronic or the fork magnet it would have eventually gone anyway?

Yeah its hard to say as there isnt much info on these

But seems to not like the oil change after a certain amount of time thats for sure

most likely the fault was there for quite some time. just the symptoms became more evident with fresh fluid.
It's impossible to tell when it happened.

but if the fluid was not replaced, eventually it would have led to a total failure of the unit

Okay so right now regardless:

1. Have to pay for someone to take apart the engine and have a look into the gearbox
2. Either have to pay for a new fork (cheaper) or a new mechatronics unit (expensive)
3. Put it all back together and hope for the best

This doesnt sound fun - is there any way i can claim this on insurance or anything to some how get out of paying $2k+++

Hi,

I'm just going to pipe up here and have a bit of something to say, given the following.

1 ) The shift fork repair was originally designed by me, then modified by Dodson to get what we have today (you guys are welcome) :)
Without us doing this, everyone who broke the sensor would be looking for a second hand box.

2 ) I have been working on the SST for quite a number of years, so, if you have any questions... hit me up.
I don't tend to frequent the forms all that much (hence my user name), so best to catch me on my fb page. https://www.facebook.com/mnautos

3 ) The approach that Jarryd mentioned... Pull mech unit and look in the hole and see if in fact the shift fork sensor has broken,is your first step.

4 ) I would be very surprised if an oil change has caused this issue, the reason being is that 90% of the boxes with a broken sensor I see,
have all had clamping forces of the clutches ramped up by 'tuners' who are unaware of the shared line pressure.

5 ) Ramping of the line pressure to makes the clutches hold tighter, inadvertently increases the speed at which the shift fork moves.
How do I know this??..... I have the oil flow diagrams :)
Think of it like this, you can close a door with a window all day long and not incur any issues, SLAM that door and you may just break that window.

6 ) Jarryd has been one of the most patient clients I have ever had, he had one of the original forks that wasn't up to scratch
Jarryd has been more that helpful with assisting us.

7 ) We work closely with Beeble, and Dodson to bring you guys rectifications and a safety margin when tuning these cars and the SST box.

8 ) I am the specialist, that the 'specialists' come to for SST assistance.
You can confirm this with AK Racing, RTR, Agostino Mitsubishi, and most of the Ford dealers down here given the 6DCT450 and 250 are used in the Ford range of products.

These are the facts.
Forget the internet pseudo mechanic nonsense.

Unfortunately, Elliot - Trouble... you need to pull the mech (as Jarryd suggested) inspect the fork. Take the next step from there.

If the car had the SST recently tuned, then you may have a recourse of action there. (most of the time, it's a.... too bad, not my problem)

We can assist in the rectification of your box, contact me via my fb page for more info.

I hope this doesn't come across in a bad tone or me talking myself up.
I have spent a lot of time trying to determine the causes of some of the issues and the rectifications for you guys who have the SST.

I wish you all the best what ever way you decide to go.

Damien.

p.s Stay tuned for some other goodies for the SST.

Thanks for the great insight Damian. So from these two comments I am taking away the fact that the S-sport/LC flash upgrade is slowly killing our transmission..... Is that right.

Just asking as I've been reading Daniel Gieger who is an SST guru as well(Kozmic Motorsports) comment that driving the car in normal mode is not good either when driving in a "spirited" fashion and s-sport is better for longevity.

I'm confused and sorry to hijack the post.
