[Silly Little Cars] Transmission Woes.

Tue Sep 8 10:34:27 PDT 2015

Hello,
I’ve got at 2004 and I get all my parts from:
http://www.fourgreen.com/store/Scripts/default.asp
On the right and side there is a search by part #.
I’ve never had a problem get gasket sets, rebuild kits or just common parts.
Every good prices, fast shipping and genuine Hyundai/Kia parts. 
The I3 I think is the replacement for the Atoz/Atos.
Hope this helps.

Thanks for the link Larry.

The problem is that the cooler module on the transmission IS the cooler. 
It doesn't route hot  ATF to the radiator and cooler ATF back to the transmission.. The little module is an actual heat exchanger mounted right onto the transmission housing. 
I assume they normally dont go bad, but it happens as I may have learned.

My assumption is that this issue is an old one and somewhere down the like the P/O tried to band aid it.

There is a secondary radiator and fan in my 08' mounted in the front of the rig under the hood .. 

After examining the routing of the hoses it looks like the cabin heater is first in line before everyone on that circuit. 
If it's always been this way I'm not sure but then it goes from the heater core to the secondary radiator then to the trans cooler... so the transmission appears to have plenty of cooling as far as water temp goes.

The heat exchanger on the transmission is Hyundai/KIA part # 4610002700 but the parts aren't available through Hyundai or KIA because the dealers don't have access to non US parts lookup.

Here is a site showing the module in some detail. Теплообменник АКПП JF402E JF405E 99-up 4610002700 96567484

FYI the transmission is a JATCO JF405E.
Master overhaul kits are available through Cobra transmission for about $375 but the cooler is unobtainable.

Theoretically I could go with an external cooler configuration but I'd have to machine a custom block off plate with ports to take the fluid out and back. 
I don't see any ATF in the coolant and I haven't had the cooler out yet to pressure test it. I'm hoping the contamination is caused by ingress via filler tube. that way at least the clutch material adhesive won't be attacked by ethylene glycol. But if in fact the contamination happened during my trip and hasn't been lingering I may have caught it quick enough to flush it out with minimal damage. but I still need to test the cooler. 

So I'm still putting a request out there for a replacement cooler or if anyone has a spare transmission lying about I'd like to see what you'd sell it for. Remember this is an '08 I3 and it has the 4cyl Hyundai engine 

Thanks!
jon
