my 2000 ram 1500 runs great but transmission shifts in and out of second,going back to first then upshifts to second until vehicle speed increases. this happens only from dead stop going uphill.if shift lever is placed in 2nd from stopped position this problem does not occur.any explanation is greatly appriciated. Thank you.bilandsam@yahoo.com

 

your tranny cannot determine which gear is better for hills so it serches either hit the pedal a little more so it stays in second or alittle less so it stays in 1st
