3 torqueflite questions...

sorry- I had ground in the middle- WRONG
I have a centrifugal switch in the spedo cable (I use the one found in 73 400 used to control the EGR but there are others)
I use this to control relays for electric fan but it could be used to disconnect OD and lockup when coming to a stop
others use the brake light switch
Factory has the converter unlock during shifts
early 85 converters unlocked when throttle was closed (switch on carb)
I do not like coasting unlocked cus I tow and you get less compression braking
anyway you do not want to go slow or stop with the converter locked
there are several relay kits available- do some research
