Could be cable or linkage out of adjustment. Verify from underneath is actually in drive before you do anything else (with a helper)
truck will only go forward not in reverse does this mean the transmission is gone
No it will not. Sounds like the transmission has a major problem.
No there is not. Whats the problem no heat ?? If so try this, reverse the heater hoses on the heater core and then go drive the truck and see if you get heat.
The transmission
a transmission problem
No, the first motor truck was built in 1896 by the German automotive pioneer Gottlieb Daimler. Daimler's truck had a four-horsepower engine and a belt drive with two forward speeds and one reverse. It was the first pickup truck. Ford built his first truck in 1900.
because xavier is in the way so they cant go forward!!!!
1996 gmc 1500 truck will not go in reverse
(Obviously) release the handle. Then "force" the truck in a drive gear; reverse or forward until it releases. Then in the future do not set it as tightly.
you messed your truck up
Yes
You are probably low on transmission fluids
