If you did the conversion yourself, you need to go to Bow Tie Overdrives on the web and get their advice ASAP. Those transmissions can be burned up very quickly if the trottle cable isn't set up properly and it can't be done "by ear", must use a pressure gauge. It isn't loke a 350 or 400 that can be set up by feel.

Now that I scared you to death, a lock up converter has a clutch in it that literally locks the fluid coupling so there is no slip when the car is cruising in 4th gear. Since all fluid couplings must slip a percent or two in normal operation, the clutch improves efficiency and gas mileage. Again, to use this feature in a non computer car, you must get a modification kit, and again Bow Tie Overdrives can supply that. The conveter should lockup and unlock automatically depending on transmission demand and you can't do that manually.

Yep -

Go to <a href="http://www.700r4.com" target="_blank">www.700r4.com</a> and get the lock up kit. You also need to get the TV cable dialed in right also. BowTieOD's also has a nice kit for that.."TV Made Easy". I also recommend installing the manual overide switch as directed in their wiring diagram. It is nice to be able to switch the systme completely off around town at low speeds. Espcially in a lighter car, or one with rather low rear end gearing. The converter locked up in OD with a 3.70+ gear feels like you are trying to drive a manual tranny in 5th gear at speeds aroud 30-40mph.

Good Luck.
