Transmission Cooler question

Running a TH350 in my Dodge Truck project.

For my initial startup and engine break-in, can I just block off the cooling line ports in the trans? I won't be driving the truck...just running it for the required amount of time and RPMs.

Will this cause a load on the trans at all that would require cooling lines?

Before I put the front end back in, I'll have to remove the radiator, so I don't want to have to fill up the lines and connect them to the radiator only to have to remove them.

Hoping I can just put fluid in the trans and block off the cooling ports till it's road worthy.

 

loop them together, blocking them could cause issues.

 

yup loop em

 

Junk yard,,,,ford crown vicks used to be police cars have a nice heavy duty factory trans cooler in them,,,I run one in my 51 with no problems and no cooler in the radiator...

 

Many full size trucks have coolers also, be sure to flush it well, dont know whats been thru it.

 

Do Not Block OFF loop only also use trans hose not fuel line. good luck
