Symptom
Probable cause(s) Notes
Poor
acceleration;
flares on starting
off in D, D3, and
R
1. Low ATF level
2. Shift cable broken or
out of adjustment
3. ATF p u m p w o r n or
binding
4. Regulator valve stuck
or spring w o r n
5. ATF strainer clogged
6. Torque converter check
valve defective
• Check the ATF level and check the ATF cooler lines for leakage
and loose connections. If necessary, clean the ATF cooler lines.
• Check for a loose shift cable at the shift lever and the
transmission control lever.
• Check the line pressure.
• Check the ATF strainer for debris. If the strainer is clogged,
f i n d the damaged c o m p o n e n t s that caused the debris.
• Improper alignment of ATF p u m p and torque converter
housing may cause ATF p u m p seizure. The s y m p t o m is
mostly an rpm-related ticking noise or a high pitched squeak.
• Be careful not to damage the torque converter housing w h e n
replacing the main ball bearing. You may also damage the
ATF p u m p w h e n y o u torque d o w n the main valve body. This
will result in ATF p u m p seizure if not detected. Use the proper
tools.

1. 1st accumulator
defective
2. 1st clutch defective
• Check the 1st clutch pressure.
• Inspect the clutch piston, clutch piston check valve, and 0 -
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, and inspect the clutch waved-plate height. If the
discs and flat-plates are w o r n or d a m a g e d , replace the discs
and flat-plates as a set. If the waved-plate height is out of
tolerance, replace the waved-plate. If the discs and plates are
OK, adjust the clearance w i t h the clutch end plate.
