Fit my 2003 Silverado 2500 HD with the 6.6 Duramax diesel option with the Allison 1000 transmission. Sealed off a leak I had it coming from the dipstick tube seal in the transmission

This part was OEM part number as I checked with Chevy before installation. If you have upgraded your downpipe, it's a bear to install but can be done. Remove RF tire and splash guard and be ready to get deep into the back of the motor. I did it by myself with no lift. BE PATIENT, as you try to get the pipe to re-seat into top of Allison, it will slip up over the lip on the tube. Keep wiggling it will go into tranny.
