I got a 93 f150 with 5 speed. I was on my way home and i went to downshift to stop at a light, and i grabbed ahold of the lever, and nothing, it wont move at all. I put a considerable amount of pressure on it. Its got a jasper unit in it now that was there when i bought it. Anyone got any ideas?

 

If your clutch is not disengaging fully, it can make it stick...

You might make sure no linkage is fouled up.
If you have a hydraulic clutch, check the fluid level.

 

No the clutch is working fine, the reason i know that is because i am able to drive it in 4 low
