It seems the pin at the base of the shift lever is more than resistant to being pushed out.

After many days of applying penetrating oil and various attempts at twisting and pressing the pin out with less than ideal tools I started to risk heat.

At first I went the safe route of inserting a soldering iron into the set screw hole and letting it set for 6 hours. Though hot enough to burn myself the heat of a soldering iron just does not expand steel much.

Then I used a long reach butane lighter with as much results. Or maybe I needed to let it burn for several minutes. Hotter than a soldering iron it still had no effect.

Yesterday I built a heat shield to cover the top, sides and ends of the base of the shifter lever and clevis. After wetting the foam above liberally, I put a hose on misting and inserted it above the heat shield. Then I applied my propane torch for a good portion of a minute and applied more penetrating oil.

I am suspect that even if I got the base of the shift lever hot enough to get penetrating oil into the gaps, I still would not have the leverage to twist or push the pin out.

I am looking at the connection of the clevis rod to the transmission so I might disconnect it and pull the assembly out (?) and get access to work on the pin with substantial force. But I can not even see all of the connection much less get to it.

Has anyone ever used Muriatic Acid to dissolve rust?
