a) Check gear oil level/condition. b) or you have a worn synchronizer. Verify that your clutch linkage is adjusted, if this is a cable linkage vehicle. Hydraulic units are not suppose to be adjustable. Your difficulty with getting the vehicle into first gear could be a result of the throw-out fork not fully releasing the clutch disk; hence the above suggestion to verify that the clutch mechanism is adjusted properly for full travel of the throw-out fork.
Cable too slack.
My 1997 would not shift out of first gear, was 'throttle position sensor'.
From the neutral position, pull the shift lever toward you then down, this would be frist greer, aka first gear.

Shift linkages not put in the correct spots.

bog down in first gear and then it strtes to shift
To fix a gear shift light, the first thing that needs to be done is checking the fuse box to make sure that all fuses are intact. The reason you would fix a gear shift light is, so you know what gear you are in. Driving in the wrong gear can cause transmission problems.
It is probably a linkage problem
If your turbo 350 won't shift out of first gear, it could indicate a frozen transmission gear. You should first check to ensure the fluid levels are in the right place.
