I just got my trans built last Monday and it seems that when i am in the middle of 3rd gear with the converter locked my truck seems to be jumpy. All of the stats on the computer show nothing that would cause this. I feel it is just the hi stall converter. but idk? Anyone have this problem?
---This doesn't happen when i am on the throttle hard. only when i am going throw the gears slow with the converter locked.
