Dead Transmission - 4EAT?
Posted: Tue Nov 10, 2009 6:02 am
Just bought a '92 Legacy L sedan to fix and put back on the road.....it has tranny issues.
Car won't move @ all in 1st.
Moves in 2, 3 & D, but has only one gear - 3rd- Doesn't shift up or down - Hey, it's a CVT!
Reverse works, but car is slow to engage.
I drove it home on back roads @ up to 45 mph, and started to whine the longer I drove it (just like the ol' 4EAT in my '90 except all its gears still worked 'til I swapped in the turbo 4EAT).
Once up to speed (30+) it would accelerate up to 50, and it climbed the previous owner's steep 1/4-mile long driveway w/out too much complaint.
Tranny fluid doesn't look too bad, but does smell 'crispy'.
NO TCU codes stored, either.
Just wanted to confirm it's beyond a flush/refill/pray?
And what does a bad torque converter act like?
I've got an extra tranny waiting for deployment (Thanks Lee!), so I'm covered either way.
Thanks

Edit: Found this from the USMB site - endwrench LINK:
"If shift solenoids #1 or #2 malfunction, the TCU
deactivates the other. This results in either 3rd gear or
Reverse (when selected).
If duty solenoid A fails, line pressure goes to maximum.
If duty solenoid B fails, the torque converter lock-up
will not occur.
If shift solenoid #3 malfunctions, the overrunning
clutch is always ON and there will be engine braking
during deceleration.
If duty solenoid C should fail, the AWD control will
be set to maximum and the rear wheels will always
be powered."
But it should throw a code??!
