Hey guys I have a 2001 silverado 1500 with tranny problems and need your help. I had the 4l60e tranny rebuilt 15 months ago after the sunshield failed and put around 8000 miles on the odm since. Over the past month a very slight shudder could be felt while running in od. This happened maybe 6 or 7 times. Last week I pulled out of my driveway and the tranny shifted late and hard from 1st to 2nd but not into 3rd only high engine rev. Parked it for 2 days and now it has no gears forward or reverse. Checked fluid level started engine but no change in level. Fluid looks and smells like new. What are your thoughts? Thanks
