trans cooler on a 6MT

[funkytown]

Hey some of the 6mts run external transmission coolers right..?

Where about do they plumb into on the gearbox...?

[Tony]

There is a metal tubular line which links the front and middle casings on the gearbox. On the cooler equipped ones there will be break in this line which has hoses on it that lead to the radiator bottom tank where the trans fluid is cooled (same as how it is done on auto trans in some cars) rather than a seperate external cooler. This is on the Spec C's I have seen - not sure if any of the models actually had external coolers as such? Maybe someone else can chime in about that....

On the non cooler equipped cars the line has no breaks and just goes from front to the middle. To fit a cooler you need to remove the line, cut it and braze some fittings on each end and then run the lines to an external cooler. Easy.

Its probably a good idea to use an auto radiator and utilise the "cooler" part of that as it will keep the gearbox fluid at a consistant temp rather than possibly cooling it down too much. Same idea as using a thermostat for an external engine oil cooler.

where is this...

ok i found a picture of a box -

point to me where "a line" runs to and from on the gearbox side... ignoring what the lines connect to in terms of coolers.

[Koom]

Wrong side.

Can see it in this pic;

right perfect thats what i want to konw.. it is that bango and metal pipe on the braket between front and middle sectoins... just behind the axle stub?

Should be. I'd braize a weld nipple onto the banjo piece, after cutting the pipe off, and then use AN fittings from there.

Or if using a factory auto radiator, I'd just cut the pipe and put hose straight onto it (we've got the tool that makes the wee raised "bump" (technical terms elude me right now) on the end so they don't come off though).

[funkytown]

thankyou sir.. .

you have a pm regarding other such matters.

why weld a fitting onto the pipe from banjo? you could just buy a banjo part, thats ready for An fittings. thats all i did for my turbos.

unless they dont go big enough lol

it's just the spec c boxes that have a cooler, i believe they also have an internal pump???

All the 6MTs have an internal pump I'm sure. I know mine does as when it got rebuilt last time Anton said the pump was still in good condition and had no issues...

Local speedway shops didn't have the correct thread when I was doing a similar job and was going to take me about 4 fittings to get it to do the same thing. Only reason I chose to do it that way.

[funkytown]

right to revive this thread -

I need the part circled:

1) to hold the gear linkage

2) a line to link the rear to middle sections in lieu of a trans cooler line

Also -

a) what does the tube on the top of the box do near the bell housing?

b) i cant seem to find where the speedo cable input is.

c) what goes in the bolt hole above the main selector shaft? (looks like a neutral indicator)..

edit - ok so c is that sensor - i dont have one - what is it? and where will i find one?

speed sensor screws into same place like a 5 speed box nad youl need to run your 5speed sensor as well

there is no where for it to screw into ... ???

Il go have a look for that sensor on my 5mt

[nt_a_foz]

its just behind the bellhousing part of the gbox on the drivers side..

theres a 20-30mm odd hole that will either have a sensor in it already or a thread for your 5 speed one

[funkytown]

Arrr!!! so i found a electrical switch thing in the speedo hole.. took that out and my 5mt one goes in the hole nicely, as did the 5mt neutral switch thingy, including the plug to the harness

Whats this pipe nipple thing for?

[funkytown]

this pipe.. where does this go / what does it do?

Probably not my place to say funky, I'd say it's a breather like on the auto box's

thats what im thinking - next is to figure otu where it goes..

[nt_a_foz]

Dont think mine had one of those??? cant remember to be honest

[wrx_lou]

didnt you pay someone to put yours in though mr muny bags? ;D

[funkytown]

go look now and tell me where yours goes.. you should be able to see on the firewall.. its the bell housing end that i need to trace now

[Guest boostcut]

im sure its just rubber hose that traces up the firewall and has a hook shape on the end of it...

[Tony]

It doesnt go anywhere, it just ends at the top of the bell housing. It is a breather.
