Low ATF level

of adjustment
Shift cable worn
ATF pump worn or
binding
Regulator valve stuck or
spring worn
ATF strainer clogged
Mainshaft worn or
damaged
Final gears worn or

Transmission-to-engine
assembly error
Axle disengaged Check the ATF level and check the ATF cooler lines for
leakage and loose connections. If necessary, flush the
ATF cooler lines.
Check for a loose shift cable at the shift lever and the
transmission control shaft.
Improper alignment of ATF pump and torque converter
housing may cause ATF pump seizure. The symptoms
are mostly an rpm-related ticking noise or a high
pitched squeak.
Check the line pressure.
Check the ATF strainer for debris. If the strainer is
clogged, find the damaged components that caused
debris.
Inspect the differential pinion gears for wear. If the
differential pinion gears are worn, replace the
differential assembly, replace the ATF strainer,
thoroughly clean the transmission, and flush the cooler
and lines. Replace the torque converter.
Be careful not to damage the torque converter housing
when replacing the main ball bearing. You may also
damage the ATF pump when you torque down the main
valve body. This will result in ATF pump seizure if not
detected. Use the proper tools.
Install the main seal flush with the torque converter
housing. If you push it into the torque converter
housing until it bottoms out, it will block the fluid return
passage and result in damage.
Vehicle moves in R,
but not in D, D3, or

Inspect the secondary shaft and 1st/1st-hold/2nd clutch
assembly for wear and damage.
Inspect the clutch piston and O-rings. Check the spring
retainer for wear and damage. Inspect the clutch end
plate-to-top disc clearance. If the clearance is out of
tolerance, inspect the clutch discs and plates for wear
and damage. If the discs and plates are worn and
damaged, replace them as a set. If they are OK, adjust
the clutch end plate clearance.

tolerance, inspect the clutch discs and plates for wear
and damage. If the discs and plates are worn or
damaged, replace them as a set. If they are OK, adjust
the clutch end plate clearance.
