E4OD TC Lock up

Unread postby snowman429 » Mon May 08, 2017 4:24 pm

Ok so I finally got my bronco back on the road. Yesterday while driving down the hwy I noticed my TC would unlock on the flats/light load but as soon as i started up a overpass or gave it a little throttle the TC would lock up. Can somebody help me out with this? I'm new to all this tuning stuff. Thanks

in all stock tunes the tcc is set to unlock at closed throttle

check all the torque converter unlock parameters you have access too, one of them is most likely causing it to unlock

Well after hours of messing with stuff trying to get the tc to lock up correctly I finally figured it out. All it was, was a burnt out 3rd brake light bulb. Replaced the bulb and all is good.

that should have been obvious in the log, your brake switch bit would have shown on
