that is a suzuki SPORT. 1.8L (wide frame) J18 engine-
the understroked J20 engine.
and is a very rare car, even new was rare......!!!
for stores selling wrong parts, that will never fit a Sport.
all 5sp boxes M/T
the transmission uses GL4,fluid, gear lube 4 (API spec)
first make sure the right side plug (front never touch rear bolt)
is loose. 10mm square drive it is (all parts on car are metric)
then the books are free, need links.
the bottom has a matching plug, that drains.
as does the transfer case if 4wd, is car 4wd?
here is the stuck side plug, photo.
last goon used 3/8" drive wrench, and stripped it. its 10mm only
so the mech here had to weld on the bolt .
also when car was new the plug was factory caulked.
after 20 years and not serviced, (common)
that caulk is like diamond hard.
so we heat it up. with a torch first if hard to turn CCW.
the 5speed is convered here in the FSM
the operators guide covers it , Lost yours?)(
the opr guide chapter 9 page 10 covered that. if lost here it is
the 89-98 are all same box. same words in all operators guide in print. 5 speed.
keep a copy.
finding good GL4 is hard, many stores dont sell it.
or only sell axle lube. GL5.
