you said , it wont shift to 4th gear, OD.
but will i bet on flat ground, and you back of the throttle with right foot, right?
the transmisson and the TCM are both setup to not shift , up, at huge throttle angles, the TCM and the TV both do that. (in some secret combination)
the TV and the TCM are both TUNED (calibrated / programmed) to shift with a NORMAL 95HP engine
if the engine is weak, then both fail.
only testing in manual mode can prove that case... drive with the TCM unplugged.
if it dont slip and power is weak then the engine is in fact weak, and all else is useless, worrying about a/t.....
this transmission is tuned for 95hp, not 50.
see?
a shop would find out that first...... (engine issues are first)
the newer Vitara/s 97+ the TCM is inside the ECU(Now called a PCM)
and you cant unplug tcm (ecu) or engine dies...
so they unplug the trans side connector (left)
starting in 1997,
which connector is more easy, I dont know. (depends on the person doing it) crawl under car, or under dash (panels off to gain access, TCM is way up high)
see?
they dont make cars easy to fix. its not in the list of goals...
unplugging the tcm , forces the transmission to only use ITS internal manual valve. for all gears. 1,3,4, rev.
