LPEZR1 Posted July 29, 2003 Report Share Posted July 29, 2003 Just noticed that if you put it in 2nd while stopped, truck will start off in 2nd. Cool feature, next time it snows down here in central Texas I will use it. Link to comment Share on other sites More sharing options...

56chevywagon Posted July 29, 2003 Report Share Posted July 29, 2003 My 99 Z71 had the same function. Didn't realize it until I had to replace the ECU due to a JET Chip Module burning it up Link to comment Share on other sites More sharing options...
ledfootss Posted July 30, 2003 Report Share Posted July 30, 2003 found that out on my 01 z71 i quess there is a reason for it Link to comment Share on other sites More sharing options...
rmcswain Posted July 31, 2003 Report Share Posted July 31, 2003 Yeah, wonder what reason Link to comment Share on other sites More sharing options...
BenKey Posted July 31, 2003 Report Share Posted July 31, 2003 Correct me if I'm wrong here, but it's an automatic, meaning you can start in second or third, but it will still start from first and then go no higher than the gear you have selected???

SinisterSS Posted July 31, 2003 Report Share Posted July 31, 2003 Highest torque to the rear wheels occurs in first gear due to the higher numerical ratio than second gear. First gear = 3.06:1 Second gear = 1.63:1 Dividing the two gears to find the "ratio" between them gives - 1.63:1 / 3.06:1 = 0.53 = 53% Therefore starting out from a stop in second gear in a slippery road situation such as water, ice or snow will send 47% less torque to the wheels than first gear. This limits wheel spin in low traction conditions because there is nearly half the power being delivered to the wheels. Speaking of 3.06:1 first gear ratios - I just love how the SS leaps off the line. Torque multiplication rules! Link to comment Share on other sites More sharing options...

jwest1975 Posted August 5, 2003 Report Share Posted August 5, 2003 Thanks for the heads up. If I need it, I will try and remember that this winter when the snow hits the ground! Justin Link to comment Share on other sites More sharing options...
