I took a good working t5 out of a 85 gt to put into a 91 4cyc project the tranny sat for about a month with fluid in it, finally got aorund to finishing the project drained and put redline fluid in the tranny, and it wont go into 2nd now??????? i drove the car for months and it was fine before but now from just letting the tranny sit it dont go into 2nd??? its like it hits a wall or somthing just pops out, ive tried other shifters also what could have happened
