Trans Cooler line help (1 Viewer)

[CruiserDave]

OK replaced my radiator, fan clutch, thermostat , etc recently and the other day one of my transmission cooler lines starts to leak. Well come to find out that the fan shroud had caught the line the goes from the cooler to the bottom of the driver's side radiator and pinched it.

Now I'm looking to replace it and can't tell if its part# 32943B or 32910G ?
It has 90* bends like 32943B but has a cover over the hose like 32910G.
OIL COOLER & TUBE (ATM)

So to clarify it is the hose that is under the battery box that connects to radiator by the drain plug and to the metal pipe that leads to the cooler under battery box. Can someone help me figure out which hose I need.

Thank you for your time

Picture might be helpful...

32910G is the one attached to the cooler itself.

The easiest thing I found was to use power steering or hydraulic hose(3/8 inch ??), and one of these to make that 90 degree bend unicoil | NAPA Auto Parts

Problem is Mr.T used 10mm hose. 3/8 hose is a little too small and must be forced on the nipples stretching it out some. I have never been able to find 10 mm hydraulic hose anywhere. Sure would be nice if someone found a source for some silicone 10mm. But you gotta use what you gotta use. Not many people will throw down the big $$$ for the entire transmission cooler assembly just to replace a hose or two.

So I did the exact same thing and just painted the whole block with atf. Does anybody know the which hose goes into the cooler on the driver side of the radiator? I’m having a little trouble with the diagram

The bottom hose from the air/oil cooler goes into the drivers side of the radiator.

I used Gates 3/8” transmission fluid hose when I replaced all those trans cooler hoses 4 years ago. The fit was a bit snug but they have held up well.

3.8" is ~9.5mm and it does fit as mentioned above. One way to look at it,
it might be less likely to leak at the pipe connections, but that 1/2 mm difference is not really an issue, just use a swipe of ATF on the hose and pipe to get it started.

After searching all over the net and physically going into to half a dozen different auto parts stores I was unable to find true aftermarket 10mm ID transmission cooler hose. One brand sold in Australia that stated it was 10mm on the package was actually 9.5mm, confirmed by email direct
to the company that made it.

For one of the cooler hoses (long section running from the pipes to the
right side radiator) I used two formed power steering return line hoses from non-Toyota vehicles and cut them to fit when installing a cooler line transmission filter in the circuit. They were also 3/8" ID. No issues getting
them on the pipes.

There may be true 10mm ID hose being used on another Toyota vehicle that's still available that could be made to fit?? The complication is that someone would need to buy (?or order, compare, and return) a bunch of different hoses until they find something that's close in length and shape that will work on our 80's.

In lieu of that the 3/8" bulk transmission cooler hose (or power steering return hose) is all I've found. FWIW.
