Changing auto trans hard lines

02 v6, auto. Northeast car.

Rearmost (on trans) hard line leaking at the union fitting. Bought both hard lines,"adaptors" and orings online.

Typical struggles with rusty fittings on a NE car. Short story, rear one is loose, and off the adapter (elbow). I am going to try not changing the elbows as it looks pretty dicey threading them in without hitting the pan.

Had to use heat on the rear union (think BIG brake line fitting) which worked out, I think, buy using a think copper heat shield (for TIG welding) to keep heat from the wires behind it. Hopefully I managed to keep the adapter cool enough to not damage the oring. We shall see.

With that out of the way, physically too, I was very unhappy to find the front line is VERY close to a sensor and cable. So close I am not sure I can keep from damaging it with the torch. I guess this is where one of those "induction" heater deals would fit in?

Suggestions? Looks like removing the sensor might be a real PITA.

 

Ordered a cheaper model of an induction heater thinking it would only head the union nut, pipe and fitting. However, since it works by creating intense magnetic field, of unknow "size", gotta wonder if the sensor has any magnetic/ferrous bits in it that could be damaged.

Thinking creating a U shaped "shield" out of steel to put between the coil and the sensor which should (?), deflect the field away from the sensor.

Yes, no, maybe so?

A picture or two would be nice.

I have taken a small dremel with 1" diameter cutoff discs and split the female side of various pressure fittings over the years, you slice it enough to get a screwdriver blade in and twist it and relieve the pressure/rust to allow the male part to unthread. Fortunatly for me the female portion of the line set was the easiest line to take out. Went through lots of those dremel cutoff blades, lots of them.

 

I've done that as well. Problem here is the female part is an "adapter" that fits into the side of the trans. If I cut that, I have to replace it and the "physics" of the parts makes that problematic without removing the pan and maybe other stuff.

I ordered an induction heater and will fashion a steel shield an get an aerosol "Cooler" can to spray on the sensor. Hoping for the best.

 

These are the problems that take the fun out of tinkering, I hope this isnt your daily driver.

 

No, but it would help if it were running.

So far the induction heater has not done the job. It certainly gets hot and smokey, but even with the shield I am being wimpy about getting the sensor/switch too hot. Letting it soak overnight again in acetone/ATF mix.

Mean time, I was taking the rubber hose of the radiator tank cooler, which had been off cleanly before and stuck back on to not drip on me, when the metal tube it attaches to on the tank, broke off, for "no reason".

Anyone know if they are available or do I have to spring for a new radiator?

 

Maybe...
