Check for a stuck lock-up valve in the valve body.
• Set the idle rpm in gear to the specified idle speed. If it
doesn't fix the problem, adjust the engine and
transmission mounts.
• Check the ATF level, and check the ATF cooler lines for
leakage and loose connections. If necessary, flush the
ATF cooler lines.
• Check the ATF level, and drain the ATF if it is over filled.
• Inspect the clutch piston, clutch piston check valve, 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 or damaged, replace them as a set. If they are
OK, adjust the clutch end plate clearance.
Check all clutch pressures.
