Reality check - Part II

[Charlie Chops 1940]

Finished plugging the 4th gear pressure tap on the side of the 700R4 yesterday and lacking the parts to do the lockup inside the tranny as some have suggested I rigged another microswitch on my B&M shifter to lock up the convertor when the shifter selects 4th gear. Works just fine although I now have to manually select 3rd to unlock the convertor. I'll drive it that way for a bit and see how much of a PITA it is and go to the other mods if I don't like it.

The best part is that the leak fix campaign is done. After I took it out for a 10 mile run this afternoon I parked it on a fresh hunk of cardboard and there wasn't drip one after a couple hours. One thing for sure, I'll never use an external pressure switch for convertor lockup again. I can't tell whether the brass reducer was cracked before I broke it off or if the pressure switch sprung a leak, or both.  

So, time to move on to more motoring pleasure.

If you are going to have to manually select between 3rd and 4th why not replace the microswitch with a toggle or push on-push off?

Not as much work as rowing the shifter back and forth.

Point taken Sum. I'll give it a little time and see.
