89 Subaru
Justy, Transmission Problems
Q: I have a 1989 Subaru Justy with the ECVT (Transmission). My question
is when should I have the belts in the transmission replaced? I have 150,000
miles on this car and have noticed some hesitation (loss of power) on
inclines especially in cold weather.
A: The
belt drive transmission in your Justy is an engineering marvel, yet it
will be a marvel if the engineer who designed it will ever get out of
therapy. Your description is not of a belt problem, it's more like an
engine performance problem. Due to the complexity of your vehicle's operating
system I strongly recommend checking basics first: ignition system, filters
etc. If the problem still remains, inspection of critical input switches
and sensors to the transmission's computer should follow. The electromagnetic
powder clutch makes use of a brush set that should be inspected but this
requires removal of the starter gain access. Your Subaru's ECVT transmission
requires only a qualified technician if service is needed.
