1988 Ford e350 transmission dip stick part numer
 

Picked up a 1988 Ford e350 with 7.5 engine assuming C6 transmission and it doesn’t have the transmission dipstick. Dealership can’t look up a part number so I turn to you all for help. If anyone has the same setup or know where I can find the part number so I can search for one that would be awesome. Plus non of the junkyards have a 1988-1991 e350 so no help there either

You might have some luck with one of these :
Vintage Parts Inc
Beaver Dam, Wisc. or,,,,,,,,,,,,,,,,, Trans shops always have some old trans hanging around and they just might have an old case with a tube in
good condition with dipstick and all. Shop around could be worth the effort.

Being an 88 with a C6, I seriously doubt a dealer would have it anymore.Likely discontinued long ago..Try

I have requested a current catalog from a company that supplies dip stick tubes and related parts. As soon as I get it I will pass it on to all.
