Hey just installed a rebuilt 48re transmission with a triple disk billet converter. I'm just trying to figure out some issues. The truck will manuall go into reverse 2nd and 1st with no issues. Though it will not go into drive, the dash recognizes it but not the transmission. Also park will work but the dash will not notice it? Can anyone please help??

 

check linkage first then get the solenoids scanned.if you start having reverse issues it will have to come out
