A
used transmission is just that, a used transmission.
They are just guaranteed to be a used Datsun Roadster
transmission, with no broken gear teeth, nothing more.
We consider them cores to rebuild, repair or use as
is. If you want a completely good transmission,
rebuild one or repair one.
If
I was to go through any 5 speed and put my name on it
the cost would probably end up about 5-10 times
whatever prices are listed here. If I was just to tear
one completely down to note even any visible problems
it could raise the price by 50-100% just because there
are so many things pulling at me to do them these
days. And that would assume I could ever accumulate
that much fun-time i.e.sitting on a stool at my
workbench arguing with some snap rings. I miss that a
lot. I remember one time when I had about 8-9 boxes
all laid out and did them like an assembly line. When
they were all done I could have done another in my
sleep.
WHAT
WE DO: 1500/1600
Oil
pan is pulled off and a visual check is made for
broken gear teeth, broken forks or something else
obviously wrong. It is NORMAL for the reverse idler
gear to look a bit beat up. Transmission is shifted
into each gear and hand turned to check response. This
is only a simple inspection and check, MANY things can
not be apparent (bad bearing etc). Countergear is
wiggled to check for gross internal bearing wear.
Synchro's may or may not function properly, there's no
way to check them accurately without the transmission
being checked in an operable car. Sometimes we can
tell if a one or more synchros are COMPLETELY gone,
but NOT ALWAYS. Transmissions with obvious problems
are set aside or sold with a specific part number with
their own specific description, but if you want a
trans with nice synchros, put new synchros in! Oil pan
is put back on, with the OLD gasket, or remains
thereof. You should ALWAYS order a gasket and seal kit
if you don't already have one.
WHAT
YOU SHOULD DO: 1500/1600
The
biggest problem with these is the bearings and shaft
inside the countergear gets worn then the counter gear
can move away from the mainshaft. At certain times
only the tips of the gear teeth are engaging, which
leads to them shearing away. ($$$$). ALWAYS yank the
front cover and rear tailshaft housing before
intalling a transmission (or when you do a clutch job)
and check the shaft and bearings. Unless the shaft is
MINT (no visual change to surface) replace it and the
bearings. ALWAYS replace the countershaft bearings.
Servo boxes use caged needle bearings, Warner boxes
use individual needles. On the Servo boxes there are
bearing spacers inside each end of the counter gear.
Don't lose them as they are getting impossible to
find. Normally your old ones will be useable. Be sure
to order the appropriate gasket and seal
kit.

with the OLD gaskets, or remains thereof. You should
ALWAYS order a gasket and seal kit if you don't
already have one.
OPTION
2:
Rear tail housing is removed to check for VISIBLE 5th
gear problems. It STILL can be slipping in use and
feel OK with hand test; this look just determines if
it is OBVIOUSLY in sad state do to loosening etc. Tail
housing is just loosely reinstalled, with the OLD
gaskets, or remains thereof. You should ALWAYS order a
gasket and seal kit if you don't already have
one.
OPTION
3:
WHAT
YOU SHOULD DO: 2000
Always
replace the rearmost countershaft bearing with the
latest production version of the bearing (#323-02, on
2000 TRANS page hit link for BEARINGS AND BUSHINGS).
Be sure to order the appropriate gasket and seal kit
as well.
