raker79 Posted December 30, 2008 Report Share Posted December 30, 2008 i just finished installing a magnacharger system on my truck. the truck wont shift out of first gear unless i let off the gas and the same for second and third. Im not sure if it shifts into 4th at all. i do know that the toruque convertor is not locking up on the highway. everything else seems to be working good. the shifts, when they do happen, are smooth and there are no CEL's. when i accelerate in 2nd gear it will shift into neuatral it seems and shoot all the way up to the redline. any ideas? what acctualy tells the trans when to be in what gear. or any good shops in metro detroit i can get a hold of.

raker79 Posted December 30, 2008 Author Report Share Posted December 30, 2008 never got on it. just never worked form the get go. the gears and TC feel fine. only thing i can figure is it is a sensor of some sort that is telling the trans it needs to be in first for some reason.

Fireman31 Posted December 30, 2008 Report Share Posted December 30, 2008 Did you tune for the Maggie? If so what kind of tune are you using? Quote Link to comment Share on other sites More sharing options...
raker79 Posted December 30, 2008 Author Report Share Posted December 30, 2008 tune from magnacharger. (superchips tuner) i have contacted them and they have no idea what the issue is. had me put the stock tune back in and the problem is still there with the stock tune. i have since put the supplied tune back in so i dont rune lean.

DAVECS2 Posted December 31, 2008 Report Share Posted December 31, 2008 (edited) I have seen issues were the calculated torque is way beyond the table and the trans will not shift until the torque returns to a value listed in the table that will allow it to shift. You may need to clear the memory on your PCM. I am not sure how to do that with a hand held. There may be some values that are throwing out some odd calcs on torque. On a cold day I can outrun my torque tables and my PCM cuts engine power for a brief second. I would warn though that if your trans is stock it will not live long behind a supercharged 6.0L.

raker79 Posted December 31, 2008 Author Report Share Posted December 31, 2008 let me start off by saying i do not know to much about auto trans's, always have been a manual guy. but the trans and the TC both feel very solid to me. the shifts are firm and the TC never slips. it just doesnt want to shift gears when the pedal is beyond about 10%. now im not saying it might not be broken but it was fine before the SC install and as i was pulling out onto the street (before the super charger ever even engaged) i could feel something was wrong. my intentions were to bring it in and have the trnas upgradded some yesterday. but i would prefer to get a better grasp on my issue before i take it to a trans shop or performance shop and have them start throwing parts at things that dont have issues. also im not to sure about the shops in the area, i have never had luck with the shops understanding techincal problems, they seem to be more mechanicaly inclined.

raker79 Posted January 6, 2009 Author Report Share Posted January 6, 2009 well guys just thought i would shoot an update. unfortunatly everyone is correct. the 2-4 band is shot, the drum is crushed, all the clutchs are gone the TC needs to be replaced and some other stuff. i will have a better idea on wed when it is all completed. the good news is nothing to bad was broken and it will all be replaced with upgraded parts ontop of vette servos and a a shift kit and some other upgrades. ill shot over a complete list when i have one.
