2003 chevy silverado trans in limp mode
I have a 2003 chevy Silverado 5.3 4l60e 4wd. the trans is in limp mode. its stuck in 2nd but i can shift down to 1st. also no speedo. and the odometer is going crazy , it goes through the languages on its own.
about 3 months ago i was driving home from work and i was going up a hill (at about 60-70 mph, not real sure, speedo didn't work then either) and out of nowhere the truck kicks out of gear. eventually i slowed down enough to catch 2nd gear and got it home slowly, i assumed the transmission went out completely, as it had been slipping quite a bit. well i parked it and was waiting for the time to put a new transmission in and eventually about 2 weeks ago id had enough of the waiting and sent to the transmission shop. they rebuilt and when i got it back it was doing great until i got a mile from my house. then it kicked out of gear and back to square one. i realized that second that i had spent $1100 for nothing. anybody know whats going on?
