Need new torque converter

Recommended Posts

I have a 2015 GMC Sierra 1500 6.2. 71000 miles   I need a new torque converter.  I know there is no science to how long before it damages the transmission or totally blows up.   What is the average best guess on miles I can drive before I’m SOL.   I need to get 500-600 miles out of it.   

Thanks in advance.

usually if you need a converter, your gonna need the Pump too , your parts cost is already over $1000 for pump and converter, the more you drive it the worse it gets..


try just pumping out all the trashy fluid via cooler line, i would run 3 gallons of fluid thru it

i had the tcc go out on mine and i guess i was lucky because they were able to flush the trans and there was no damage to it. just a new TCC and good to go.
