This is a much needed kit when you are rebuilding the top shifter of a T90. This kit includes 2 springs and 2 poppet balls. These springs have the correct spring rate unlike other competitors out there. We highly recommend replacing both springs and both balls which is why we sell this in a kit to take the guess work out. Sometimes a failed spring can be this issue with the transmission staying in gear, especially 2nd gear. Fits:
