Here is what the guide that came with my B+M rebuild kit for a TH700R4
said.........drive along in high gear at a steady 45 mph, if you just barely
touch the brake (without removing your foot for the gas) and you should see
the tach shoot up 200-300 rpms as the converter unlocks. It worked with that
tranny (83 s-10 blazer) and also works in my 93 explorer. I never tried it
in the 2000 Dakota though.

I would think any trans made in the last 15 years or so are all have lock-up
torque converters due to gas mileage requirements. The lock up causes a
no-slip condition in the torque converter and so there is no power loss due
to slippage.
