How To: 1 mount to 3 mount Tutorial 7G.

Okay so i was told i couldn't use my 1 mount tranny, cause i need a 3 mount Tranny..

Basic tools need.
10mm socket.
12mm socket.

One mount Tranny is a 1G.
Three mount is a 7G.

Both Auto Trannys.



I'll try my best to explain, step by step.
that i did.


First i set the Trannys side by side..
i look @ both.
they look the same but there not.

This a picture of the one mount Tranny.
No Side Mount.

As you can see on the cases thier completly different.

Heres how to fix that problem.

Take out all the bolts to the one mount tranny first so you Get the feel of what your doing.

after all the bolts are out around that part of the case do the inner ones..
and that case will pop right off.

Now do the same with the 3 mount tranny.

and u'll have a 3 mount Tranny.
Now thats not the end yet..

Now its time for censor changes!

Step 1.

See the plug deal under the shifter plug in.( in RED )
its pretty small..it pulls out.
But heres the deal.
See the censor below?.. thats what the picture above is about..
after it's pulled out take off the oil pan.. u'll see this device held in by two 10mm bolts.. Switch em.. but it back on like it was with the other one.
Now thats done!

Next step.
in the picture below your gonna have to swap em out..
http://i71.photobucket.com/albums/i1...alant025-1.jpg
Theres a pin holding it in that has to be Sqeeze together to get it out..

Next step..

Now this part isn't tricky..

The picture below has two pieces highlighted in red.
now only the one mount Tranny, have censors in that place..ones missing in photo though.

The three mount tranny are in this position..but the one circled is where the one on the front Case is gonna go..

Now it's time to move onto the shifter.

Switch them around Cause plug in's are different..
held on by two 10mm bolts..and the center ones a 12mm.

After all that it's ready to be put in, pluged in.. and filled up.



I will add better pictures later with more of a Hands on thing..
i just gotta clean up the Garage some!

Thanks, 95GalantOwner!

wow, so you are swapping bell housings. Hopefully itll work out. I wonder if it works for manual trannies. cant wait this to be done! For some reason Ive always found 1g trannies in the yard, and never 2g or Galants

It does work.

thats whats in my car now.

I don't know if it'll work for Manual Tranny's.. But i'm sure it'll work..

someone correct me if i'm wrong, because this post just confused me to hell and back, but don't the manuals already have 3 mounts? i don't understand this thread because my automatic was 3 mount....

yeap MAtt! Hes swapping auto trannies from 1 mount 1g to 3 mounts 7g by exchanging the bell housings and some sensors. What hes trying to say is that the transmissions are the same, but they have different bell housings

instead of using the 2G or 7G tranny he was using the 1G

oh.....a 1G tranny...i missed that completely

1G tranny with the bellhousing of a 2G or 7G

yea yea i get it now thanks guys

Sorry for all the miss understanding i will correct the info on this!
ASAP.

I take it the axles stay the same?

Yes they stay the same..

i mean i haven't had a problem with it so far!

So the 7g axles fit in a 1g gearbox?

Yes they do..





for an update.. The transmission is still going strong.


:smt117

Gear ratios between 7g trans. I believe the 7g 5spd is similar to the 2g GS Spyder non-turbo ratios.

7G and 2G GS transmissions are identical so you are right Seth.

the axles are not. for the 2G at least

on Proto's eclipse his 7G axles wouldn't fit into the 2G trans. the hub side were ok but the tranny side the 2G is thicker.

I used to use a set of 2g raxles with no problem.

hmmmmm. he had to buy 2G axles.

i dunno maybe wierd tranny? it's built and all. maybe they made special axles for it?

Although I do remember the first set of used 2g axles I used did not fit into the 7g trans, they were thicker, so there may be two different types or spline counts for 2g axles. What year was his 2g trans from?
