I have a 1995 Ford Contour GL 2.0l 4-cyl auto that has some tranny problems........It constantly upshifts and downshifts under normal throttle pressure. Then sometimes it acts like it goes into neutral hits rev limiter then slams back into gear that alone will hurt my tranny internally very quickly does this seem like a electrical problem? Sometimes it will shift 100% fine.........for a min or two

Problems b4 hand..........
Transmission slip from drive to overdrive (suddle)
Used engine degresser got all over the engine and never covered electrical componets.......
