Hay folks
I'm hoping I could ask some members to do a little test drive for me to make sure 100% that the transmission glitch i have is a problem and not just a 380 thing
what i need you to do is
on a flat road very gently accelerate maintaining 1000 rpm, at 40 kph the auto should shift into 4th gear
continue to accelerate holding 1000 rpm through to 60 klms
If needed manually select 4th at 40 klms and continue as above and let me know what happens
In advance I really appreciate anyone who can pop out and do this for me
I haven't mentioned the issue I'm having because I want to keep an open mind for the test

kindest regards Andrew

If you hold out at 1000rpm until 60km/h it'll shift into 5th

ye if you keep it at a steady rpm on a flat road it will shit to 5th if going over 60km/h and back to 4th if under 60km/h....

Same with the 3rd gen 4 speed, gets into top gear at 60, but drops back to 3rd if speed drop only slightly.

Annoying to have the box change gears all the time in city traffic, but I think it is done on purpose for best fuel economy test results at a steady 60 KPH.

Thanks for the info mine shudders in 4th at 45 to 55 its going in for a assessment at an auto transmission place its under dealer warranty I was just wondering if it was me and the way I drive it sometimes. often where I live I find myself driving very gently because of 50 zones and traffic
In another post a member suggested going to MM and getting the learned values wiped??? suggested this to the Dealer but he wants the car so he can get it looked at by his people the dealer has been pretty good but I can just feel on of those "its a torque converter no its clutches fix after fix with no resolve although Im not paying I have to borrow or hire a car each time it goes of the road I've been driving real hard trying to teach the box the last few days but the shudder still presents its self under the conditions I described
Its just odd that there are no other symptoms as a box its perfect otherwise also had it serviced and refilled with genuine fluid (saw the stuff arrive and go straight in so 100% Mitsubishi fluid
any further advice or experiences always appreciated

If you listen to what i have said you will have your problem fixed much, much sooner.

RESET THE LEARNED VALUES WITH A MUT3.

an after market diagnostic tool cannot do it.

Zilo appreciate your advice but aren't shift points are set to change into 4th at 40 5th 60 others have confirmed this is normal if the box learned and adapted to driving styles why would resetting learned values
need to be done I've been caining around for 3 days now and it still doesn't hold gears any longer does your auto change into 4th at 40 doing 1000rpm if i reset the learned values the box will still shift into 4th at 40 cause thats what its programed to do i need you to explain to me why resetting learned values will fix a physical shudder

Okay, sounds like you've got it all under control.

Hay Zilo
I haven't got it under control lol I just wanted as much info as possible
I think you find this amusing
I cancelled the auto trany booking and instead went to my local Mitsubishi dealer to book in to have the transmission ECU rest or rather the learned values they looked at my like it was an idiot they then brought out the machanic who listened to me and then rang the dealers other dealership to find out about the procedure he came back to me and proudly said just disconnect the battery for a minute then do a relearn procedure shift into this gear and that etc thats all we need to do i tried to explain that the memory is stored regardless and that this is stated in the service manual I think they got the sh*ts then so I guess I will just have to ring Mitsubishi dealers till i find one who knows what they are doing or give the service manual to the local cross my fingers

So what are you complaining about?

The low throttle shift values or the shudder?

Apparently there is an additive that can be added to the 380 transmission fluid that cures the shudder, but you will need to do a search on what that additive is.

Shift values - can be adjusted in the transmission computer, but you need to get an expert on reflashing to do that.

Why not try using a heavier foot and holding the gears in whatever gear you want manually?

Disconnecting the battery does not reset the learned values in the transmission.
The relearn procedure does not work, i have proven it.
I had exactly the same fault....and it is fixed.

Don't listen to Madmax...(he knows stuff all about 380's),
an additive will not fix it, don't waste your time or money.

I think Mal suggested an additive to stop 380 transmission shudder at one stage?
(But excuse me if I'm passing on incorrect or out of date information. :facepalm )

The 380 auto is programmed to shift to 5th at 40kph.

The 380 auto is programmed to shift to 5th at 40kph.

Which would be at about idle RPM. Could the physical shudder be engine shake rather than gearbox? (noticed this on a Commodore, the auto box changed up to top gear far too early on light throttle and hung onto it far too long slowing down, leading to a physical shudder.)

Perhaps select gears manually and keep the RPM in a range where the engine and gearbox feel happier?
Unlike manuals, automatic cars need the driver to adapt his driving style to what the engine/gearbox are happy with.

I always changed gears manually in my KW and always changed to 5th at just a tad over 40kph without any shudder/shake and yes the revs were 1100rpm or there abouts. I wish my Pajero could do that as it has way more torque but won't allow manual change to 5th unless it is doing 55kph.

I'm surprised at that because both my TJ and TL 4 speeders need at least 60 kph before they will go into top gear. A heavy foot, and the change doesn't happen until illegal speeds! lol

cheers MadMax stuff all about 380s eh lol I checked out the additive the Mal mentioned I reckon Ill buy some just in case
physical shudder is the sort of thing I was wondering about thats why I was asking other 380 drivers to try to recreate it in their car Its a funny thing It reminds me of taking off in a manual in the wrong gear anyway here is a update
about 1500 klms ago I got a transmission service well so i thought $160 for a flush and fill the bloke said the oil was filthy and dark I hung around while they did the service and made sure original fluid was used yesterday a thought occurred to me (after reading other posts about transmission flushes and one bloke had 10lt put through his to get a good flush) I think they just drained 5lt and refilled it I decided to drop the oil and have a look and it was s**t so 20lts of atf 5 of which remained in to box the shudder is gone!!!!!!!!! and the oil is red clean
so to sum up trust no one ha ha
transmission flushing was easy, I was not game to do it according to the workshop manual, each oil drop drained almost exactly 5lt, oil comes in 5lt @ $47.75 I let it drain bout half an hour 5lt back in then pour the old oil into the empty container if you put a mark on the oil container where full was you can keep track of the quantities in an out go for a drive and repeat my last drain was almost perfect I will do another flush in about 5000klms to be sure alls well I would say the transmission had never been serviced in its 160000 life fingers crossed theres no permanent damage
thanks again for everyone's input helpful as always

dead on Zilo clearly stated in the workshop manual pity Camden Mitsubishi have no clue how to clear my memory
If you had this done please give me the contact details of who did it maybe he can walk my local through the procedure even though the shudder is fixed i would like this done to check all the boxes

who cleared your learned values? maybe he can advise Mitsubishi here how to do it

I have my own Mut and did it myself.

It's not hard to find, it's in the transmission subsystem menu, the data menu, then the special function sub menu.

A generic or aftermarket OBD tool cannot see that far into the system so it has to be a MUT3.

After doing it you just drive for a few minutes, but the 4th gear transition shudder disappears instantly.

my TL had a trans shudder, even with fresh fluid and re-learn. I put in a Nulon additive, made it a bit better. I put in a tube of Shudder Fixx, Mal had it, completely fixed the problem. or you can get it at DrTranny.com

ended up buying 2 tubes off ebay got them in the spares box just in case. The 380 auto is 100% now thank goodnesss
