On a turbo 350 trannie, how do the cooling lines normally connect - top line from the trannie to the top fitting on the radiator/transmission cooler?  Lower line to the lower fitting?

ive been told its not a big deal to mix them up, especially if your using an aftermarket cooler.

  using the principal of a coolant system,...hot fluid goes up,...then cools and goes down,.......you could start it for a second and see what line shoots out fluid.   that would be the line i would put on the top.

I don't know where I have the picture stored but...
The pressure line goes on the bottom. To make sense of this I have come to assume that the pressure line pushing fluid through the system will eliminate air pockets that would come about if the fluid was allowed to free fall from the top of the cooler to the bottom...factory or aftermarket cooler.

Thanks

There is a bunch of stuff floating around. I had to do plenty of research on my own to retro-fit the 700r4 into my 67 C20 and then into the Monte. Both applications used the cooler-in-radiator and an aftermarket cooler. I used NPT to -6 fittings in the transmission and ran braided line for the coolers. I had to use steel tubing in & out of the radiator then use tube to -6 adapters for the braided line.

Bigee2:

  The best way to cool an automatic trans. is to install a seperate trans cooler. The bigger the better. Either way you hook it up make sure you flush the crap from the trans lines and if reusing the radiator cooler. You may want to install a trans inline filter. Scott has the correct set-up illustrated. Grin  Cool
