Transmission cooler

Post by mickeytopher » Fri Aug 09, 2013 10:01 am

I just noticed that on the wife's 02 Neon that the previous owner completely bypassed the transmission cooler on the radiator and hooked it up to an aftermarket tranny cooler :banghead: Are there replacement lines out there or would a couple of lengths of rubber fuel line work.

...assuming that the original transmission cooler on the radiator even works

the aftermarket one should be fine honestly, even better off if one decides to burst. if the factory one bursts internally the two fluids can mix resulting in a ruined transmission. if they're separate like they are now, that wont happen. but if you're dead set on puting it back to stock, yes rubber fuel line will work.

IMO the previous owner just did you a favor :thumbup:

The only thing you may consider is an oil thermostat if you live where it gets cold. (Below 60ºF)

The 41te does not like the fluid to be too cold.

I have used those t'stats a couple of times, and they have worked flawlessly. Since the cooler is there, you might only need to spend for the perma cool unit and some hose barbs to make it better overall.

The ATX will get up to temp faster, and maintain a good 180º operating range. It will keep it from overheating, and from sludging up.

Justin is correct in that they did you a favor. It is cheap insurance against a $1500, or more, transmission repair.


As far as the rubber line, just tell them what you are buying it for. They will hopefully sell you the proper stuff. You will need to get a little extra if you install the t'stat.

I would keep the aftermarket cooler regardless if the one in the radiator is leaking or not - just for extra cooling capacity.

However, like Occasional and r/tguy have pointed out, the factory radiator has a known issue in that the built-in trans cooler is prone to failure and internal leakage - Causing antifreeze to contaminate the transmission.

If you don't like the looks of the aftermarket cooler, or the previous owner did a 'hinkey-looking' or sloppy installation, consider getting another auxiliary trans cooler, and / or re-mounting it, the "right" way. :thumbup:
I've tried to mount mine, so that it looks 'clean', and not sloppy.
