[Shotimes] Tranny noise

[Donald Mallinson]

The infamous SHO MTX tranny noise is only heard in first 
gear.  When you pull away from a stop and are next to a wall 
or something that can reflect noise, you will hear the gear 
rollover "rattle".  No grunch.  This rattle is standard on 
every SHO MTX ever made, and is helped slightly by running 
Redline MTX fluid, but that only mutes it slightly and 
REdline D4 is the better fluid to run in later SHO's with 
the fiber syncro material.

If you have a clicking sound in three gears(it is probably 
there in other gears, just masked by other noises at the 
higher speeds), then this could be something serious.

IF you don't have a drain plug on your tranny (they have to 
be added, they aren't there from the factory) then you 
should take out the fill plug and use some sort of pump to 
remove some fluid from near the bottom of the tranny.  Check 
for a LOT of silver (aluminum) in the fluid.  A LITTLE is 
normal.

The gear rollover is not a tick, it is a heavier rattle. 
You can tell the difference, just get next to a building in 
a fairly quiet area and do a few low speed FIRST gear 
takeoff's to about 5-10 mph.  You will hear it and get used 
to the sound.  I have not heard a SHO do this particular 
noise in any other gear including reverse.

A ticking in the tranny could be the infamous spider gear 
shaft working its way out.  or it could be something in the 
clutch.  More likely the clutch, especially if the noise is 
consistent in both first and reverse.
