Quick Aux Trans cooler question

Just installed my trans cooler Hayden 404
I downloaded the b&m instructions just to use as a go by. B&M suggests flow from bottom to top when mounting on its side. Does it matter either way? Is top to bottom better?

NOPE-bottom to top allows the tranny fluid pressure to force the fluid thru the cooler--

If you go top to bottom, airpockets form and cause tranny TRAUMA !

Good luck

the reason you do bottom to top is to push the air out of the cooler on start up. if you went from top to bottom, it will make a air pocket in the cooler.

Thanks again to both of you. I did it as per B&M instructions. I'm just glad to be on the winning side of a 50/50 chance for once! I'm no mechanic and it took me less than two hours including a trip to oriely for better hose clamps than Hayden supplied. Easy and inexpensive upgrade.

Sounds good-

Mine is a little more involved, I have a frame mounted (racing) finned aluminum cooler that feeds in the B&M type in front of the radiator-

My tranny has never got over 200 F, even on slow hill climbs/w trailer



Chryslers auto tranny cooling system is actually a tranny warmer

So anything you can do to help the cooling is great-

Good luck

I'd like to put a tranny oil temp gauge in like yours. Was that difficult DIY?

If you've never wired temp transmitters and low voltage receivers before--it's difficult-

SunPro makes the tranny temp gauges 0 to 250 Degree 12VDC and also includes thermal/temp senders that you've gotta insert into either the tranny pan, or one of the coolant hoses-

It's not easy-

most guys nowadays use the superchip/phoneapp--whatever-
