I may have missed it but in the beginning you said you had it wired for a one wire lockup.do you lock it up with a dash switch?doesw it only lock in 4th gear?if its locked does it drop out by itself when it automatically goes into a lower gear or will it stall when you come to a stop?

There's a small pressure switch threaded into the 4th gear apply circuit on the valve body, so yes, it only locks up in 4th. I run the 12v through a toggle switch to turn it off. It will drop out of lock-up when I slow down, but only when it downshifts out of 4th.

I only use 4th gear when I'm on the freeway, and leave it in 3rd for around town driving. I run a 3800rpm stall converter from Precision of New Hampton that has a strong 3 carbon fiber disc lock-up clutch. The combination of high stall & lock-up affords the best of both worlds. It's like having a 5 speed automatic, as it drops the rpms between 300 & 400rpm when engaged.
