So fired my truck up after work and started driving home. Got up to about 50mph and the convertor banged into lock up pretty hard. And that was with accelerating up to 50mph with about 1/4 throttle. It seemed fine after that since I stayed above 50mph most of the eay home. Got off the highway and slowed down to around 30mph andd the convertor started going in and out of lock up. To make sure it wasnt up shifting and down shifting I turned the o.d. off and it continued to do it. Made it home shut the truck off. Came out an hr later to run somewhere and now its working fine. What would be some of the stuff that would cause this? Second time out I logged the tps and everthing looked normal
