Have torque converter issues
GM knows this.
It's called in Time the torque converter could be swapped out without rebuilding the transmission.
Unfortunately I did not catch you sometime had to have a complete transmission rebuild which cost me thousands of dollars.
The transmission shop I went to know this and upgraded to a bullet torque converter and rebuilt it.
I've been a proud Chevy owner with trucks getting well over 300,000 miles with no problems.
Will not buy another Chevy 3/4 ton until GM builds a better truck along with being more conscientious to their customers.
