THM 4L60-E - PUMP INTERCHANGE

1993 -1994 MODELS:
Pump Body - All models use the 10 Vane rotor and slide assembly, and this Pump Body has the same casting and worm track configuration as the 1985-1993 models of the 700-R4 transmission. Refer to Figure 3.

Pump Cover - All models of the 4L60-E have a larger diameter filter seal bore, as shown in Figure 1 and is the easiest way to distinguish the 93-94 4L60-E Pump Cover from the 700-R4 version. The 93-94 4L60-E worm track configuration is shown in Figure 5.

1995 -1996 MODELS:
Pump Body - All models use the 10 Vane rotor and slide assembly, but this Pump Body has a different casting and worm track configuration than the 93-94 model Pump Body and will not interchange. The 95-96 Pump Body is easily identified with "PWM" cast into the front side, as shown in Figure 4. The "Bolt-On" bell housing was also introduced in 1996, which required the added "Flange" to center the bell housing. Refer to Figure 4.

Pump Cover - Has a different casting and worm track configuration than the 93-94 model Pump Cover and will not interchange. The 95-96 Pump Cover is easily identified with "PWM" cast into the back side in the location shown in Figure 6.

1997 MODELS:
Pump Body - Has the same worm track configuration as the 95-96 "PWM" Pump Body, but a 13 Vane rotor and slide assembly was introduced, as shown in Figure 7.  The 13 Vane slide has longer "Porting Slots" as shown in Figure 7.  The "PWM" is still cast into the front side of the Pump Body. Refer to Figure  7.

Pump Cover - Has the same worm track configuration as the 95-96 "PWM" Pump Cover, but the "Porting Slots" are a different configuration than the 95-96 Pump Cover, to accommodate the changes in the 13 Vane rotor and slide.  Refer to Figure 8.  The 13 Vane Pump Cover is easily identified with "13 V" cast into the back side of the Pump Cover in the location shown in Figure 8.

INTERCHANGEABILITY:
