Im having an issue. With a trans shudder but im hesitant to belive its the trans. Everything is as u see in sig. Trans has about 60k and regularly serviced. With xzt on power mode. Around 45-50mph light on throttle I get a shudder( like somebody shaking you not lock unlock). If I flip xzt down a notch it goes 95-100% away. Or if I push throttle little further it will clear up. Seems to just be at that 1250 1300 rpm mark. This problem just came on all of a sudden after truck sat around for about a month while getting painted. I've towed about 4klbs with it and problem was no worse just the same. Thanks for any input on what to try.

Sounds like my truck is doing the same thing but I have the 6spd. We have the same chip and mine will act the same when I flip the clip down. I have tried all the APPS voltage and stuff and it just wont get rid of it. I just ordered a new Timbo APPS last nite and hope it will fix my problem.

Lemme know how that works out for u please. Starting to drive me crazy. At this point I don't careif its the engine taking a crap I just want to know so I can fix it lol. Don't feel safe towing 18k not knowing if im gonna make it home. Thanks

My 94 did the same thing, found out the line pressure was running low, the higher rpm helped the shudder until it able to adjusted, only did it in lockup at 42-454hp mph

Definitely interested in ideas/fixes anyone has. Just put the old school Xzillaraider box on my truck and sounds exactly like what is happening to mine too now...

Not sure if you are experiencing the same thing as I have , but my problems started the same way you described and the truck has steadily declined. At first I thought it was transmission issues, but I now think it is my IP. Hope you get it figured out. Good luck!

Good When I turn the xzillaraider off and just run the superchips it instantly goes away. Possible wire tap that maybe isn't so good :confused013: any other ideas????
