I just got a 85 crown vic with 50k on it . onnce i stepd on the gas and i got to about 40 i noticed it wasnot shifting, it never went into overdrive. then i mashed my foot to the floor then it went intoover drive and was cruising beautifly. then at the next light it wouldn go into overdrive again only 1st and 2nd. what could cause this? some one was telling me the tv cable ot something??
