Hello this is my first ever forum that I have joined. I discovered GM Square Body two weeks ago when I Google search for information regarding my 87 GMC P-20 Step Van fuel gauge issues. This is my first GMC truck. I am a Ford Truck man But I came across this Step Van six years ago and bought it as my future project . I have owned other half and 3/4-ton vans and pick ups in the past but this is my first Step Van. It has the 6.2L V/8 Diesel (non Turbo) and two months ago I began to put this vehicle to use. It has the large heavy duty automatic transmission which I will ID the exact model soon. The trans has a few shifting issues. The Vehicle Chassis and drive train etc is all GMC but the truck body built by Boyertown (no longer is business) is all steel. I have been able to confirm the previous owner was U.S. Air force. And it was limited to "General Use only" on the base. Which may not mean a lot but the odometer reads just over 40,000 miles. I am looking forward to learning more about it as I began the restoration. My primary purpose for the truck is to use in my Handyman business which means for the most part hauling my tools etc. all local use. The engine seems to have governors on it and the gear shifting seems to be in the low range. Not able to go over 50 MPH it sound like it wants to explode it does shift at high RPM but obviously delayed shifting and seems to be in the low gear range. Any help out there with these issues.? I look forward to learning more about this forum and interacting with other Garage Mechanics who like fixing and restoring their own vehicles.
