4l60E will not move
hello, thanks in advance for all comments and ideas! 2002 chevy z71 205,000 miles, I have no forward and reverse movement. i made sure transfer case was in gear, so then I checked the fluid it was a lil above full dark in color and smelled burnt. I came to this forum and read through trying to find ideas and info. then I did some tests that I read. checked o2 sensor fuse its good, unplugged mass air flow sensor no changes, unplugged test port above linkage I have a good stream of fluid [going to get a guage]. I jacked up rear put it in gear and tires started turning to idle speed, then I applied accelerator up to 2500 rpms and speedometer fell to zero no rotation of tires. I left it in gear [drive], after 5-10 minutes heard a click and tires started rotating to idle speed the immediately back to nothing. it did this several times. any ideas or suggestions would be greatly appreciated.
