94 t-bird trans

I have a 94 bird that down shifts and shifts up on it's own.Someone told me it could be the shift selector on the side of the trans.Is this possible?Any other ideas?ANY help will be greatly appreciated! Thanks,Ken

Ken, Just bought a 94 SC had this searching/jump to neutral problem..... 4 trans shops on phone, 2 in person ( test drive ) have to look ,pull pan etc. $50 to look and up to $1600 to rebuild.Went On SCCA.com ( super coupe of club of amer.) FORUMS and found the MLPS = Manual Lever Selection Sensor aka ( neutral saftey switch ) $ 32.95 Plus Tax @ parts store Takes about an hour,2 bolts, little tight space to work in ,located on trans side ( driver). Shifts Like Butter and bangs in when you get on it, OPPPSSSSSS... SC version anyway.These guys at SCCA are really into SC ( as well as t-bird LX ) all use same 4R70W electronic Trans.and this is common on early versions ( new one will have red rubber gasket showing that won't be on your old one.) Hope It Works as easy for you as me. Anything i can help with, drop a line. Roger
