This is a follow-up to my question about which trailer hitch I should buy; I've got a '99 EXV6 Accord and will be moving across the country next month. I'll be towing a trailer with some furniture in it, and knowing the issues that transmission has had, I've been seriously considering installing an auxiliary transmission cooler. I've been looking at this one in particular: http://www.autocarparts.com/part/937/3/

Is this much bigger/better than the stock cooler? Is there another one I should get instead that'd be better for my needs?

Any thoughts?

Thanks!

the original transmission cooler is located on the bottom of the radiator ... in other words its a part of the radiator ... the aftermarket cooler is bigger but i dont know if it will help ... i have seen small cars pulling smaller trailers i guess it all depends on the size but the v6's are notorious for transmission problems ...

yea, it's there all right...

I went and ordered the Comptech cooler (which I suspect is a B&M cooler with some cool bracketry to make integration awesome) and eagerly await its arrival.

What I'm thinking now is whether I should completely bypass the stock cooler (as the Comptech directions instruct) or should I run them in series? I'm thinking I'd have the fluid flow first through the stock cooler and then again through the Comptech cooler before it returns to the transmission. The only problem is that I don't know which tube is the send and which tube is the return from the trans and my Haynes manual doesn't help much with regard to that.

Anyone have any thoughts about running both coolers in series? I know that on the Odyssey using the Honda cooler that is installed for towing packages, it runs in series so it can't be a terrible thing.

Anyone know which tube is which?

Thanks!

I say that you should go talk to some guys at UHAUL, with a hitch installation center. I know it is possible to over-cool your your transmission as well. You do not want it to be below operating temperature. It is better to over-cool than to over-heat it though. I do not know. Do some research into it. I would imagine, that ideally, you would want one that you are able to turn off the flow when you are not towing. I am not sure. I am just thinking.

if you are going through any mountains, get a cooler...... those transmissions are WEAK to begin with

quadrinary

definitely. ordered the cooler, should have it in a week. I just need to figure out which tube feeding the stock cooler is the send and which is the return, and then i can hook these bad boys up in series and get more cooling than either on their own!

one final thing -

Just to keep tabs on all this, i'm considering getting a transmission fluid temperature gauge. Anyone have any suggestions for what might integrate nicely into my car?

Thanks!

The return line.

There are two. One line goes all the way to the left side of the radiator (you are facing the car) the other starts off a soft line which goes into a hard line connected by a butterfly clip.

This is the return line. Remove the butterfly clip, ATF will come out a bit.

quadrinary

fantastic. so the short soft line is the sending line _from_ the transmission?

Short soft goes back to the trans.
