2002 Kia Rio Transmission Internals

[zoom zoom]

So, after alot of debate and headaches, I have an early 2002 Kia Rio transmission, I have it on my kitchen table, and I have it apart. Can someone help me determine wether it's a remake of an E, F, or G series transmission, and if there are ANY aftermarket LSD's that will bolt to the ring gear?

I'll post a how-to along with this so you know what's been done.

Tools Needed:
10, 12, 14mm sockets
1 1/4" socket
3/8" ratchet & extention
Electric impact wrench
Prybar -or- rubber mallet
flathead screwdriver (punch is nice too)
Hammer
Marker
Egg Crate for storing pieces

The transmission..


Step One:
Remove the 5th Gear Cover by removing the 8 10mm bolts..




Step Two:
Remove both 1 1/4" nuts holding the 5th gear gears in place, and drive the pin from the shaft.






Step Three:
Remove 4 bolts from the housing, 1-12mm bolt 3-14mm bolts. The 14mm bolts all have springs and detent balls behind them, remove those with a magnet, don't mix them up.
This pic is of the 12mm bolt, right below the clutch linkage bracket. The other 3 are on the opposite side clustered together.



Step Four:
Remove the 14 Cover bolts & remove cover. 11-12mm, 3-14mm

Step Five:
Remove Cover






















I already went thru the entire album and resized them all, but only a few ACTUALLY resized...I'll go thru and do it again.

I have a picture of the bolt pattern for the ring gear on the way as well, it looks like it's 1.9"x8 -or- 49mmx8

I'm also looking for advice on how to pull the gearsets, this isn't the same as the G series transmission write up I was looking at and I don't want to start pulling on stuff and break it.

[FestYboy]

a bolt patern will be from one bolt to another 180* from it (just like on wheels).

ah hah, well in that case, it would be 5"

epic writeup.. thx!

It appears that this is NOT a G-series transmission, they have a 10 bolt ring gear which are riveted to the differential.

The question still remains as to what type of transmission this is.. they used this on 1.5 and 1.6L engines from 00-06 I think then switched to a hyundai beta motor and transmission.

I don't know what I'm going to do with this, if I can figure out a way of making it work I will, otherwise I'm looking at a new transmission, I'm not tearing it down any more, I see how to get the gearsets off, but I'm not going to unless I have to, there's a pin holding a pin that pushes in from the outside of the case by the front motor mount, pull those two out and the shift lever will come off. Remove the 3 12mm bolts from the shift gate and twist it off and the gearsets should pull out as one piece.

F series maybe?
I know the later proteges with the 1.5 and 1.6 engines used an f25mr trans.

It may be, I can't seem to find an up close and personal picture of an F series transmission anywhere and I've been searching 4 forum sites for the last couple weeks for any info I can get. Even if it was, quaife is the only company that I know of that makes an LSD for it, and it costs 1200+$+shipping...so it would still be cheaper for me to locate a G series and get either an mfactory differential or mazdaspeed LSD, and it would be a better transmission I think. It's a shame too, I was really hoping to have the higher gear ratio transmission on my car :[

[shadetree]

Search my posts i was told the rio trans was a g series . Why are the axle splines the same ? And as for high gear ratio ,thats incorrect its def low gear . I was running 3450 at 70 mph with mine , but it pulled like a mule .

[Damkid]

I'm wondering if it's design is based on the G series, it'd explain the similarities

[zoom zoom]

I really don't know.. lol who knows what they did.. but I won't be able to make an mfactory differential bolt to the big gear, and I can't get any measurements from a G series gear myself unless I buy a g series transmission, which at that point would not be worth swapping parts...to find out if I could even swap in the g series gear into this to make something work. I guess I'm going to have to get the capri b6t transmission and try to put a diff in that. It really sucks because that's an extra 300$ I don't have but I need to come up with. Maybe if I stand on the corner long enough.....?

Anyone need a KIA tranny?

[Damkid]

Dude I have spare diff's kickin around, I'll send you one for shipping costs

It's a 28 spline diff, so useless for a festiva application, but it's physical size is the same as a 26 spline so it'd be perfect for measuring/comparing

[zoom zoom]

I really do appreciate the offer, but I'm probably not going to do anything with this transmission. As a bolt in(fab brackets..) and go for a stock motor it would probably do fine, but it looks like it'll be too much hassle for me to do anything with it right now. I'll let it sit until I figure out what to do with it or someone else wants it. It's still a good tranny so I'm not trading it as a core charge for the new one.

It might not all be a waste yet, I may still be able to use the axels and I'll be able to determine wether the Rio hubs will work in an aspire or not....and this saves me the headache of re-wiring the instrument cluster.

This has pics of a F & G series

It may be, I can't seem to find an up close and personal picture of an F series transmission anywhere and I've been searching 4 forum sites for the last couple weeks for any info I can get.:[

It def has dif webbing on the hat than an F series....

[zoom zoom]

Yea, the 94-97 Kia Sephia G series transmissions had different webbing on the case too, but they were/are g series transmissions, and half of the guys on cp.com have been using them.
