TH350/Cooler Plumbing?
 

Which line is feed and which is return on a TH350? (It makes sense the bottom would be feed and the top return?) and on a cooler that has vertical lines, which would be feed/return?

Why does it matter?

Run an aftermarket cooler without the radiator part. Simple.

Okay I kinda though that would be okay. Not a serious converter (think it's advertised 2,200-2,400 or 2,400-2,800).

A trans cooler upgrade is a good idea regardless of your stall size. It just becomes more of a necessity with the higher stall speeds that generate more heat

Or crappy smaller converters that have bad efficiency ratings cause their re-stalled cavalier 'verters. :rofl:

I have an aftermarket cooler on the truck. Is it necessary to plumb into the radiator's cooler or can I just run the lines from the trans strait to the aftermarket cooler?

I've always done like this: http://bmracing.com/wp-bnmcont/uploa...er_techdoc.pdf

I use the stock radiator cooler also i forget without looking at my truck. I believe i go into the bottom of radiator from the trans, out the top into to cooler, then back to the trans

thanks guys.

Pending engine thermostat and cooling setup, you can easily be heating your trans fluid by using that setup. Which is why is used in stock setups, keeps your trans fluid temps stable in hot or cold, but if its a race oriented setup, I would ditch the stock cooler all together.

If you drive it in way cold temps, just be wary that your trans may take a while to warm up, but again, race car. Its also less fittings,and hose to leak. Makes taking out your radiator etc. a lot easier.

:shrugs:

Yeah, too cold can be a bad thing in a non-race only vehicle.

Well right now I have the radiator cooler bypassed. I'll see how it goes but I didn't want to hook it up cause I didn't feel like re-plumbing it after I saw Bonzo's diagram. I guess I'll see how it does for now.

Just let things get warmed up before you nail it, simple enough, and most likely the trans will be warm once the engine is at temp.

I don't run mine through the radiator and it doesn't go into lockup until there is some temp in the trans when its cooler out.

No lock up... no worries?

Maybe it will lock up... worries?

Hopefully not. No wires running to my trans :lol:
