Question tune shifts?

i was driven the other day not long after id gotten into it and my shifts felt wierd. i would get into it and it seemed the top three gears shifted early or something and after it would shift while iam 3/4 or full throttle it would defuel for a long time acted like it luged the engine bad then it would take off? any answers or sugestions to my problem? it didnt seem to do it before when i got into hard and when i drive normal it doesnt do it at all.

sounds like your tranny was just adjusting to your driving. what tune were you running? i know these trannys learn quick. just drive it normal for awhile and see if it the shifting comes back to normal.

mine does it too... its because the engine was very cold. it is the tuning that makes the shifts do that. if you let her run for 5-10 at high idle before you take off it shouldnt do it. i put my chip on a lower setting for the winter anyway

oh... if it was doing it when it was warmed up then i'm not sure. when mine is cold it does it but then after a few times through the gears it stops, and that isn't letting it warm up at all either. when i let mine warm up for 10 min it usually doesnt do it then. maybe someone else can help? maybe e-mail eric?

haha i know what you mean. one of my friends was with me one morning (that hasn't a clue about diesels) and i barely pressed the gas and we flew through the first three gears and then it backed off really fast. he was like dude wtf are you doing. i was like nvm if i told you, you wouldnt understand. maybe your tranny or converter is having trouble learning since extreme race locks 2nd-5th. i am always real careful to learn my tranny b4 i go rompin on it, i would cry if it broke because of my idiocy lol

maybe its just me idk? maybe the tranny just got used to it and when it did i thought somethin was wrong? does your tranny shift like that on extreme race? in the uper gears like it defuels or kills the engine when it shifts then takes off real quick? my looney file never did feel like that just shifted hard and kept the rpms up.
