So, I just finished installing a used but in good shape t5 into my 66 mustang. when I take off in 1st, 2nd, and 3rd, it makes a whining sound like I have a supercharger. I mean loud like I have a procharger sc on it. What can cause this whining sound?
-when I press the clutch in it goes away, even at speed
-the sound gets louder not with speed but with engine rpm (i.e. 2000 rpm in 1st, 2nd, and 3rd all sound alike)
-I haven't heard anything with 4th and 5th maybe because I couldn't get enough rpm for the whining to occur.
Backlash in the input shaft? Backlash in the countershaft? I remember checking the b/l in the countershaft and it was .008 (spec is .005 max condition)
