The Automatic Transmission - talk shit thread

that is interesting Patto. it does sound exactly like my problem. if that is the case a bigger cooler would even be worse. i wonder if there is a way of beefing up the pump?

who were you speaking with - they seem to have a bit of an idea and if this is true Mits obviously had an idea of the issue, but i dont want them ripping out my cooler to fix it!!!!!

He is a diesel mech, and we were having a yarn about this new scania 630 (auto) he was driving... left me for dead off the line (with out a load) and i dont have the chip in at the moment.

This is some great info starting to happen

So instead of solving a pressure problem in the auto box someone, in their infinite wisdom, decided to delete the cooler as a solution.... retards....

thx patto! thats awesome work mate

Aaaaarh Mitsubishi you've done it again with another "QUICK FIX " solution .

[Storm Trooper]

I was speaking yesterday with a bloke yesterday about the Mitsubishi Auto and i told him that the later MLs they had dropped the Trans cooler.

He seems to recall hearing that this was done for a reason and believed that it was They were not getting enough fluid pressure to the torque convertor, eliminating the coller has lead to less fluid movement within the transmission producing a greater pressure and allowing the G-Box to do what it has to do.

Kind of makes sense.

This thread is working PERFECTLY.

I have just looked at mine and it seems to have the tranny cooler. 08 build MY09 model

Daryn, next time we are together you, BG and myself should swap cars for a few minutes with this test in mind. does your car feel mushy in the auto (SB off of course). again maybe the SB is an option for me but it only masks another problem. you can't fix everything by just throwing more power at it.

i think the same applies when you go a smaller diameter TC... less fluid more pressure...
i am usually suspect of my cousin, he is a bit of a motor head, so when i asked him about more performance in the auto he suggested stage 2 kits and smaller TC, now how can i argue with him when has a 9.58sec calais in AUTO.

Maybe the issue is the compliance of the system, removal of the cooler would have the auto react faster to pressure changes. As the cooler would expand slightly at the pressure increase and conversely contract when the pressure is lowered?

[patto]

Have asked a few more people last night, and they agree with with the truck mech. They seem to think that mitsubishi dropped the cooler to increase the fluid pressure in the box.

Interesting though they bought up what about the petrol autos, did they drop the cooler on them? Having a higher RPM throughput in the petrol auto may not be as affected as the diesel as it can turn out higher RPM creating more fluid pressure for the box to work properly. and can handle the circulation of the fluid upto the cooler and back.

Where as the diesel turning out less RPM, creating less pressure therefore struggling to circulate the pressure through to the cooler creating the sluggishness we seem to experience.

does that make sense???


Alright you petrol owners, does your auto box have a cooler and what are the build dates.

Im thinking i might drop the cooler they swapped over on my Tritons and see what happens. Anyone have a garage i can borrow for the day.

[borngeek]

YES patto! PM sent, be a interesting test this one

On a v6 note I could be bold and say they all have them given it looks like they dropped the cooler for around my production date onwards... (steve is JAN09 and has one.. mine MAR09 and not....)

Not much input form the MN guys but thinking none of them have a cooler???

[Quinny]

Alright you petrol owners, does your auto box have a cooler and what are the build dates.

My March 07 V6 has one ...

Q

[Cowboy Dave]

I think my MN might have a cooler. Guess I'll have to check now.

[Homer]

My V6 build date Aug '08 has one...

[marashkar]

my feb 2010 5 speed does not have one. cooler in radiator only steve

[borngeek]

thx MN guys as suspected recon they have deleted permanant...

anyone pull a AT light on a MN yet????

//i have had 4 (tow hard or sand going mental it isnt easy....)

[Cowboy Dave]

Geek my MN has 3 coolers stuck on the front of the radiator. Intercooler, transmission cooler? and, um, dunno - didn't have time to trace the pipes and stuff.

[snowman]

A/C

[fridgie]

[Cowboy Dave]

yeah that'd do it.

[borngeek]

you are a 09 build date CD? you had yours a bit longer from memory..

marashkar- thx Is that a FEB10 build? or compliance...


//will endeavour to stop at a dealer and have a sticky at their floor stock to see if I can see one...

[marashkar]

jan build feb compliance on mine there is another funny looking cooler does not appear to be connected to tranny. eng oil cooler maybe?? steve

[Cowboy Dave]

yeah 09 can't recall how early it was. second half a safe bet.

[snowman]

jan build feb compliance on mine there is another funny looking cooler does not appear to be connected to tranny. eng oil cooler maybe?? steve

the tranny cooler is black in all the ones i have seen. whereas the radiator, intercooler and air con all have silver cores.

[chaser]

spoke to my mate about the autos in these, he wont touch them because if something was to go wrong its too costly for him to offer a warrenty of some sort if you know what i mean... He is only a one man shed job kind of guy and dont want to risk it... Sorry fellas

[borngeek]

Had a look over a dealer demo MN GLX-R. (JUN10 build date)

HAS A COOLER FOR AUTO!!!

So looks like they retained them for the 5 speed auto's....


//Thx for asking Chaser

[gregned]

mine has a cooler too 5 sp auto nov 09 build date

[chaser]

u guys could try one of these kits if you are having cooling issues...

[Homer]

To be honest I can't remember if I've had "the light" in this one
Used to happen in the MK all the time when slogging through soft sand, so don't know if I'm remembering the right car

I just like having a cooler...although not if it is the cause of the mushy box
