Date: April '88
SUBJECT: THIRD GEAR START FROM STOP OR ON INITIAL ENGAGEMENT OF FORWARD DRIVE RANGE - THM F-7
MODELS AFFECTED: 1987-1988 ALLANTES
Some 1987-1988 Allantes may exhibit a condition of third gear start from stop or upon initial engagement of forward drive range (cold or hot). Owner descriptions might also be reported as a loss of drive at stops or delayed forward engagement followed by a harsh downshift into first gear on acceleration. This condition may be caused by a sticking 2-3 shift solenoid in the transaxle.
FIGURE 1 - THM F-7 IDENTIFICATION:
A new 2-3 shift solenoid went into production on December 10, 1987 (Julian Date 344). Refer to Figure 1 for Julian Date information.

Until further notice the THM F-7 transaxle exchange program, refer to Serviceman Bulletin T-87-80, should be used to service solenoid and wiring conditions within the transaxle.
