Tyranny just went out in my 2013 chevy tahoe 4×4. I did find a used 4l80 transmission. Would you recommend a new torque converter when in install this used transmission and if so which one??

 

Your putting the same old junk trans, in again, So what do you think will happen with the new piece of Junk
Sold my new 2022 back to the dealer at 3,500 mi, Torque Converter blew after the Mobil flushes, Trans went soon after, Glad to be rid of it..

 

Usually, we try to determine what causes a problem.
What were the reasons for the flushes?
Is there something going on with the converters that we are not aware?

 

4L80 torque converters are a problem because the bearing is just a sleeve bearing. Recommend putting torque converter with needle bearings instead. I had to replace transmission at 120k miles due to this.
