1998,auto,161,000kms. First started when truck was cold, it would stall when I put it in reverse. Had to wait a bit for it to warm up. Then even while driving it wouldn't shift until it warmed up more. Now when I went to shift to reverse this metal type rattle/grinding??? Even stays when I put it in park. Shift to D and it takes some time to kick in??? What do you think? Speed sensor, pcm-tcm, tranny pump, bands slipping or tranny pooched!!!!
thanks for your help.
