I got a 2004 Chevy Avalanche1500 4L60E, fresh rebuilt trans. Problem is trans has no 2nd or 3rd gear. Trans has no miles on it, well maybe 3miles. No codes in system. Reverse engages good and strong as does 1st gear. When taking off in OD scan tool shows its requesting 2nd and 3rd with no rpm changes, flaring or slipping, trans holds 1st gear till approx. 40mph and when 4th is requested shifts straight to 4th from 1st. There is no change if attempt to shift manually thru the gears. Shift solenoids are clicking when actuated with scan tool and ohm out at 21 ohms.
Any insight here is greatly appreciated.
