You really don't want the 98-99 tranny. It has no LSD. If you want a new tranny try finding one from a 95-97 200sx with low milage and, it very easy to swap out the speedo sensor. You basically just pop out the electronis one and pop in the cable one. Very easy to do.91REDSE-R said:What year transmission works best for my sentra? I have heard that the 98-99 transmission works well (no 5th gear popout). Is this a direct bolt in also how do I convert the speed sensor to the cable like I have?
