Truck belongs to a snow removal company. This truck had over 600,000 miles on it and once a rebuilt the transmission (4l80e) this truck  drove great. I was amaze how good it ran with so many miles.

Symptoms;

The truck had no reverse and would not shift past second gear.

Issue;

The front half of the transmission was completely destroyed.

Solution;

Replace the hard parts that were damage, added a master rebuilt kit, and  new torque converter
