i followed the info posted on changing juice and i assure you the driver side is out of tranny to the rad. i used it to pump mine out as the op described and it worked great. got it all. i might find the link but have no luck searching!!

 

No, your diagram labels do not agree with HUMTECH's info. The bottom line (at the trans) according to HUMTECH is the flow out of the trans (our H3s use the 4L60 trans). The top line (at the trans) is the return line. Look at your diagram where the lines actually attach to the trans (not what is drawn in the top & bottom positions within the diagram).

This also matches up to a DIY procedure listed somewhere on this site(or another) for changing the trans fluid; it says to disconnect the line at the driver side of the radiator, and run the truck as it pumps fluid out of that line.

So the driver side line (at the radiator), which attaches at the lower position at the trans, is the outlet line (going from the trans to the radiator. The passenger side is the return line, which enters the trans in the upper position.

 

so HUMTECH stated "200r4 the top connector on transmission would flow in direction towards cooler. the bottom connector returns from cooler to transmission" which is exactly what I have on the diagram, everyone agree? ...

 

No. HUMTECH was simply giving an example of how to read his table. Your transmission is not the 200-4R. Your transmission is the 4L60E. HUMTECH's table is listing multiple transmissions; go farther down in the table to the 4L60E. The BOTTOM connector on the transmission flows towards the cooler.

 

Disconnect a line at the radiator put a bucket underneath and have someone crank the engine over. As soon as the engine starts, shut it down. A little trickle of fluid should come out.
