91 ford thunderbird transmission probs
i own a 91 ford thunderbird sport coupe 2door 5.0 v8 and lately i've been having some serious transmission probs.. heres how things have gone in the past month..
bout last month, i noticed that when gaining speed at a reasonable rate, it would sputter just a bit and not have that much power, so i decided to get an oil change and i also put in some botch platinum +4 plugs.. ran great, had more pickup and go.. then just recently it started to not want to shift to 2nd and 3rd, like it would hesitate and now it doesn't wanna shift at all from 1st (mind you, this is an automatic).. fluids were at correct levels when checked too..
well, a friend of mine said that i should maybe change my transmission filter, so did so.. (how much trans fluid does this car hold?) we put 8 quarts in and its still reads low on the stick.. also, there were no metal shavings in the pan or oil but there were 4 lil shavings of some yellow hard peices that looked like fiberglass that was in the pan.. what was that? hmm.. but anyway.. after we did all this, we tried it out, still doesn't shift from 1st.. hmm..
what is wrong?! i love this car and i just don't know what happened.. it ran great for a good time and just out of the blue this started.. please, any help would be appreciated..
