Message: [QUOTE="gnxtc2, post: 1540622, member: 1414"] My truck does the same. If you're coasting, foot off the pedal and the truck slows down enough to drop gears, it'll lug. The converter doesn't unlock and when it shifts to next gear with the converter locked, it slams hard. I have Jelibuilt, Tyrant, DP, No Limit..they all do the same. Now trying to explain it this to the tuners, it fall upon deaf ears. I worked with Brian of JeliBuilt to straighten this out and he couldn't fix it. His transmission strategy is not the greatest. He might have a great engine side but his drivability is not up to par. He got tired of me calling and said, I'm doing any more revisions. I even sent him Tyrant's tunes. Right now, I'm running Tyrant's tunes. The transmission strategy is spot on. Now, if I can get Tyrant transmission tunes with JeliBuilt engine tune, now we're talking. I can live with the converter switching gears locked. Billy T. [email]gnxtc2@aol.com[/email] [/QUOTE]
