6000 V6-191 3.1L (1989)
Figure 2 - Band Apply Pin Selection Chart
ASSEMBLY COMPONENT CHANGE:
A new reverse band apply pin gage is required for all 1989 and 1990 THM 440-T4/HYDRA-MATIC 4T60 models. The 1989 and 1990 transaxle
calibrations require a longer reverse band apply selection sets. This new gage pin will make the band apply pin selection about 0.080" (2 mm) longer or
two sizes longer than if gage pin J 33382-2 is used.
SERVICE PROCEDURE:
(Figures 1 and 2)
When servicing a 1989 or 1990 model year transaxle, use the proper year band apply pin selection chart and gage pin J 33382-10. Gage pin J 33382-10
has a hex head for easy identification.
IMPORTANT:
Do not use the new gage pin J 33382-10 for selecting the proper 1-2 band apply pin. Calibrations will be affected.
Reference Figures 1 and 2 for proper 1-2 band apply pin gage.
