The 4L60 designation, while the identical for the 4L60 and 4L60E represents the fact the transmissions are 4 gears, Longitudinally positioned, The engine is able to supporting a 6,000-lb Gross Vehicle Weight Score (GVWR). Manufacture date and rear output housings are the important thing identifiers of the early 4L60 transmission and the 4L60E transmissions not indicating the E designation. This pan is bolted onto the transmission by several bolts around the lip of the pan that needs to be visible. If the pan blends in and sits relatively even with the rest of the components on the undercarriage, it's a shallow transmission pan. Examine whether the transmission pan hangs down beneath the remainder of the undercarriage elements.<img src='http://cdn3.volusion.com/f2ugc.h6psb/v/vspfiles/photos/300-000T1503Z-1.jpg' width='251' />

<br/>The rear output housing is configured with a six-bolt pattern in late model 4L60E transmissions. The bolt pattern just isn't a assured distinction, nevertheless, as early 4L60E transmissions, manufactured from 1992 by means of 1997, also have a four-bolt sample. A significant improve from the 4L60 transmission is the very <a href="http://www.4l60eguide.com/">4l60e transmission repair</a> fact the 4L60E transmission has a detachable bellhousing, permitting higher entry to the transmission parts. The E transmission designation may be faraway from more lately produced fashions of the 4L60E transmission, since all of the transmissions at the moment are electronically controlled.<img src='http://www.makcotransmissionparts.com/mm5/graphics/00000001/a74624a.jpg' width='253' />

<br/>One other strategy to distinguish a deep pan from a shallow pan on a 4L60e transmission is how a lot fluid the pans hold. The deep pan will maintain about two extra quarts of transmission fluid than the shallow pan. Without the torque converter, a stock 4L60e with a shallow pan can maintain about 6 quarts of fluid (see reference 2). Additionally, exterior sensors on the 4L60E and 4L80E transmissions are additionally identified to go bad and trigger erratic shifting.
