I am going to install an aftermarket transmission cooler. Could someone provide me with rough measurements of the factory cooler, and possibly a picture?

Thanks,
Rob

I don't have one but the following are instructions for installing the PAS and ATF cooler. There are also several installs posted here with pictures

Thanks, I tried all kinds of search terms, but didn't come up with anything useful. But, the .pdf you liked did show what it looked like, which is nothing like I imagined.

I found one that bypasses the cooler until the trans is warmed up, as I understand, too much cooling can be bad also.

I was on here a couple years ago, and posted my door lock 452T mod, and fog light stuff. Still a good board. I replaced the cabin filter ($12 ebay) and the instructions on here made it even easier.

The factory cooler from Honda was designed for a load up to 3500 lbs and doesn't use any sort of bypass for warmup. Are you hauling more than that and want more cooling for the transmission? Or are you trying to save money by using an aftermarket cooler? Remember that a larger cooler will block more airflow and may affect the cooling efficiency of the radiator.

IMHO, stick with the Honda engineered cooler. It bolts right up, no custom fitting or drilling. No running lines and having to worry about leaks. It doesn't void your warranty, so if your transmission (or engine cooling system) fails, the dealer can't blame it on the aftermarket cooler. I'm a big fan of aftermarket parts when the OEM is more expensive for no reason, or if there is significant benefit, but in this case, I think there's more piece of mind when sticking to the original design.
