BELL HOUSING IDENTIFICATION
There are currently three different bell housing
configurations, as shown in Figure 36. The is first is
the Corvette version, in which the transmission is
mounted in the rear of the vehicle, as it was with the
4L60E, and requires the torque tube from the engine
to the rear of the vehicle. The second is the Cadillac
STSV/XLRV version with the 4.4L engine, as shown
in Figure 36. The third is the standard Chevrolet bell
scheduled for trucks in 2007, as shown in Figure 36.
The converter housing also contains the pocket for the
13 vane rotor and slide assembly, with the pump cover
bolting onto the back side of the converter housing, as
shown in Figure 36. All three of the converter
housings bolt to a 6L80 case and the 13 vane rotor and
slide are common parts. The pump cover is also
common, except for the calibration differences
between the different 6L80 models.
CONVERTER HOUSING IDENTIFICATION
This manual will use the Corvette version to
illustrate and reference all procedures.
