Attention: TDR Forum Junkies I have had a problem with my torque converter unlocking between 45- 50 mph, some times if I cleaned all connection to grounds it works better for a while. I have a isolated ground wire to my PCM that seemed to work for a couple of years. I did check ad clean it. Check for codes none found. In speaking to a fellow TDR member whose motorhome was in my shop, I found out about HAPPIBOX. (also an advertiser on this site) I checked out the site and ordered the device last Sunday. It came wednesday, I promptly installed it and test drove. OH-NO 
. Problem is worse, locking an unlocking all the tome up through 65 mph. I came back home and checked all connections, found on connection at PCM not quite right, repaired and drove again, still same problem. Have any of you tried this box? Do you think I may have a bad box? Just before i logged on a fired off an e-mail to their tech. I waited because I was hoping it was something I did and I haven't been out much this week to try it. I need some help this is very annoying. Also does anyone know what wire i can tap to add a switch in for torque converter control. I don't believe it is the ones I tapped I think they are the signal wires not output. TIA Jim.

Reset tps/ apps. Performed reset and drove yesterday and this morning nothing abnormal so far. Lets hope it stays that way. Chris From HAPPIBOX called me sat morning, and was helpful for what to check and look for, I was a pleasure to do business with him.
