Post Transmission Cooler

When adding a transmission cooler is it best to take the transmission lines out of the radiator and just run them to the cooler or just put the cooler in line with the radiator. Also, can anyone tell me if you get better cooling by using an engine oil cooler or/and a transmission cooler.
This question relates to a 34 Ford with chevy sb.

I wonder that myself. Either cooler is adequate to keep the trans temperature from getting too high. On the other hand, car makers put the cooler in the radiator for some reason; they could just as easily if not easier, put an air conditioning type cooler in front or behind the radiator and cool the trans just fine. I think they put it in the radiator to heat the trans as well as cool it. In otherwords, the trans runs best at an operating temperature of 160F to 200F - less wear, sludge buildup, etc. and what better source to manage the temp than the radiator. If that is the case, radiator cooler is preferable. Any other opinions out there?

Engine oil cooler is not necessary unless you are planning very high output operation. Street Rods get by just fine w/ good oil and 3000mi oil changes.

Just my opinion but most of the factory coolers installed for off-road packages have the flow going through the radiator and then the cooler.

Definetly keep the rad cooler unless your racing, the rad cooler helps the trans warm up quickly which is essential to reduce condensation buildup. Best to plumb to the rad cooler first and then the aftermarket cooler. The reason for doing this is so if the temps outside are below zero the fluid will not freeze up and restrict the flow through the cooler, mainly a consideration in the northern climates. Transmissions need to operate between 200-275 to work properly hence there will always be a temperature differential between trans and rad.
