I recently purchased a F-550 to use as a horse hauler in the Rockies. She definitely needs some work but I have 12 months to do as much of an overhaul as I can.
1. I have the cab gutted and some serious rust removal to do inside the cab. It doesn't look like much has rusted...
1999 F250 7.3 with 4R100 Transmission
Hard shift from 1-2 when warm and slowly accelerating.
No issue when cold, accelerating, or towing.
Truck has 290,000 km and is in very good mechanical shape.
Please provide some direction on improving this shift.
