ISSUE:
Erratic or no 3-4 upshift or 4-3 downshift may be caused by normal levels of contamination in the transmission fluid. This causes the 3-4 shift
solenoid to stick in the open or closed position. The 3-4 shift solenoid is external of the transmission filter which makes it sensitive to normal
levels of transmission fluid contamination.
ACTION:
To correct this, install a new 3-4 shift solenoid and sleeve/screen assembly. The sleeve/screen assembly will protect the new 3-4 shift
solenoid from contamination. Both components are contained in service kit E8TZ- 7M107-A. Refer to the appropriate Shop Manual,
Section 17-08.
NOTE:
Always install the sleeve/screen assembly provided in the service kit whenever replacing the 3-4 shift solenoid. Failure to do this may cause a
repeat repair.
