I have a 1982 f-350 with a c-6 transmission that has only reverse gears no foward gears at all any ideas??

 

Did this happen suddenly, or did it slowly get worse over time (as in, taking a long time to engage forward when cold)?
Sounds like a rebuild is needed. If the delay when cold was present before the total loss of forward gears, it's likely from a rubber seal inside the trans. $2 part, but total trans disassembly required to get to it, might as well have it rebuilt and go another 150K or so.

 

it was sudden just happend will not shift to any gear other than reverse

 

fluids are good every gear but reverse still acts like nuetral

 

you probably broke a band in the trans.

 

My C6 was doing the same thing, I rebuilt it and found the forward clutches were completely worn down.
