I have a 99 runner, 3.4L automatic 4wd, SR5. i have a sugnificant tranny fluid leak that seams to be coming from the bell housing area. Im assuming its a input shaft seal... ?? i have done basically everything with these trucks, but have never done much with the trans but flushes. If someone can help me diagnose this somewhat, or if you believe its the transmission input shaft seal. how much work it would be to remove the tranny (tranny t-case) or how i would go about doin this project. every bit would be helpful thanks guys.
