The problem is shifting out of 1st and 2nd gear. It starts happening once the fluid is warm and thin. When i leave from a stop it wont shift out of first until it reaches about 3500 or more rpms and the same for second but around 3200 rpms and sometimes it wont shift out of second. The previous owner brought it to a shop and the took the pan off and took the filter apart and they said they found metal shavings and clutch material in the filter. My dad told me that metal shavings is common but clutch material isnt. The shop said that the problem was the pump inside the tranny and it needed to be rebuilt. When it doesnt shift out of 2nd i have to shift into neutral then back into drive for it to shift. If anybody knows a way to fix it without rebuilding it please let me know. Thanks
I don't believe at all that it could be the pump, the mechanic that checked it sounds like a quack. I did have a problem very similar to yours, and it happened to be the transmission speed sensor. The part is cheap and easy to replace, it's on the drivers side of the tranny.
I would just replace that as a precautionary measure.
