Won't shift in Drive

1981 Ford E250 Van.
302 and a C6 transmission
about 4,000 miles on a rebuilt engine and the tranny was serviced then.

I had noticed a few strange shifts lately.  Now the symptons are that in Drive it seems either the bands are slipping or it stays in the lowest gear and will not shift.
Neutral, Park are fine.  Reverse seems to shift in hard.
L1 and L2 seem fine.  I drove it home in L2 several miles ok.

This is a second vehicle and I don't wish to put much more $ into it.  I am wondering if the transmission is toast or if there is some hope of a lower priced repair?  I won't being doing this work myself and would like some knowledge before I go to a shop.  

Thanks in Advance for any advice.

Check your Vacume Modulator
External of your trans`look  on the passanger side where your cooling lines are  You`ll see a  Round cylinder type devise
with a Short hose attached to it,  Take the hose off with the van running and look for oil dripping out  ...  at the same time Put your finger over the tube that  goes upward to the engine and feel for a Vacume pull .
If no Vacume pull   Look for a vacume leak  upwards towards your engine
Ie.. follow the hose  it may have  become brittle and broke
If it leak`s oil out the Vacume Modulator  Replace that ...

Woot   Smile

Well I couldn't remember changing that out when doing the engine so I picked up a new one.  
There was some oil seemed to come out the line.  Also no vacuum to speak of.  
After changing the modulator I took of the cowling and found a hose problem.  

Seems to work fine now.  You have definitely saved me aggravation and ***  Thank you very much.  Actually words on the forum here don't adaquately express my thanks.  Smile
