1994 sho atx shifting issues

[crashman89]

Have a 94 sho atx I picked up last month and I've heard that the auto was weak but this one seems like it grabs fine most times but sometimes it can't decide what gear to be in. If I go bout 20 then go wot when second gear hits it feels like it pauses for a sec at about 4k. I'm hoping for an inexpensive way to fix it so any suggestions ????

Vehicle speed sensor mounted on the transmission provides the speed input and tells the tranny when to shift. Could be faulty. Ford still carries this part for about $45.
