Transmission line question.
While reading another post on transmission lines (talking about smoke coming from the transmission dip stick) I also have the same problem, so I checked how mine were installed (from the steel lines to the rubber hoses). From this picture, it appears that the bottom cooler line on the transmission goes to the top of the radiator (Right?). Its a stock 82 with original transmission. Looking at mine they were on backwards. It appears that the lines were installed incorrectly at one time or another. The steel line on the top of the transmission ends below the radiator with a 90 degree bend toward the passenger side fender. The bottom transmission line ends below the radiator with a 90 degree bend upward toward the hood, the upward bend goes to the top of the radiator and the other 90 degree line pointing at the passenger side fender goes to the bottom (Right?). If that's the case mine were reversed at the transmission.

Usually the rad connections are rubber hose at the rad so swapping them there is a lot easier then from under the car , and if they are hard connected you can cut and use rubber hose. You can also go under car where the lines are straight cut and cross and then use 2 brass compression fittings.
However as it is a cooler the direction of the flow should not matter , we use to always delete that cooling system in favor of a remote oil cooler on all the rebuilds we did. The reason ar 2 fold one it is better cooled remotely and 2 you can have a bad internal rad cooler leak antifreeze in to the tranny.

From the AIM drawing, it appears that the lower connection on the tranny is going to the upper connection on the radiator. There is probably a 'preferred' hook-up that maximizes cooling to the trans, but I don't think there is a lot of difference, either way you connect it.
The coolest spot on the radiator is at the bottom (hottest engine coolant is exiting the pump and sent to the top of the radiator); so having the "Converter OUT" line going in at the bottom might provide the most cooling for the trans. Again, probably not a lot of difference, either way.

Trans out goes too upper cooler, so gravity works for yah as the fluid goes thru the cooler. Like all fluids in an engine transmission fluid is just something else to be pumped and you try to min the losses. Plus the harder to pump the more heat.

It looks like the transmission lines were at one time switched around at the transmission because at the radiator end, the bends on the steel lines were backwards. I don't think the lines are factory because it just doesn't look as clean as it should (routing wise). Along that line, how many Qts. of transmission fluid are in the tranny? I went to a few places to find Dextron 3 fluid but could only find Valvoline Dex/Merc, that states will work for Dextron 3.

its the little white thing about 8-10 inches above the gear selector. some have a tube there some just that little plastic cover. its hard to get to in the car,but you can blow it out with an air hose.

My 2003 corvette transmission line which had a fitting installed few years ago, is now leaking. I have been told to replace the line. Anyone knows of a corvette mechanic to take care of this task? I live in Los Angeles, California.

Anaheim. IIRC it's Frank's Transmission. Not a "Corvette" specialty shop, just a really good trans guy.

It does take more effort to force liquid "in-up-out" compared to "in-down-out......and according to my infra-red gun, like another member said--the bottom of the radiator is "cooler" than the upper part of the radiator.
All of that combined makes a difference/maybe not a big difference...but everything helps...."kinda like" reverse flow water pumps, aluminum radiators, and electric cooling fans.
