GMC Sierra 2500HD 2006

I am considering selling my 2006 GMC Sierra 2500HD. It is a great truck and It has a bunch of really good parts, some are BRAND NEW as I was planning on rebuilding it. Unfortunately the transmission is fried and it has no reverse. I have way too many vehicles at the moment and I need to free up some parking space. The truck will absolutely need a new transmission and if you purchase it I wouldn’t recommend driving it home. Work that has been done in the past 2 years - Brand new front hubs Brand new brake calipers on both front wheels Brand new cv axle Front brakes 3 months old Inner and outer tie rods done last summer Sway bar links done last summer Controls arms done last summer Rear hubs done 2 years ago (these were the only parts that weren’t purchased brand new out of this list) Shock absorbers done in front and back 2 years ago Radiator Water pump Alternator Starter Coolant lines Blower motor and blower motor resistor Very strong 6.0 engine that has never let me down. Oil changes every 5k , filter every 10k. It has a small oil leak so I keep a jug handy to keep it leveled off at all times. This truck would be a great donor truck or if you have the means to replace the transmission, it would a great work truck or daily. I am asking 1500 or best offer.
