| | Auto not downshifting/ No burnout (LT1/4l60e)
around town the trans up shifts just fine..breaks the tires loose very hard on the 1-2 with no problem...however..occasionally ill come to a stop and attemp to power brake the car. It wont even come close to spinning the tires over. Other times it will. Most of the time it wont though. Trans was rebuilt around 50K miles ago and has a tune, stock stall speed, servo and billit trans pan. Also if it could be the same thing. On the interstate there is no "5th" gear..obviously im referring to the convertor locking up. Could this be the lock up soliniod? i was told it also controls down shifting. Around town the trans seems to downshift properly. i can feel it go into first when rolling slow and whatnot.
Also if i powerbrake the car (and the tires wont spin) if i release the brake the car doesntly powerfully excelerate immediatly..it takes a few feet then wakes up...im about to set it on fire
