* Fit-all refers to a bellhousing configured to accept either a Chevy or BOP engine.
(BOP = Buick, Olds, Pontiac, Cadillac)
Both the 4L60E/4L65E and 4L80E/4L85E have Chevy bellhousing bolt patterns. TCI® has a full line
of adapters to allow these transmissions to be bolted up to Buick, Olds, Pontiac engines as well as
popular engines from Ford and Chrysler as well.
Additional 4L60E/4L65E Notes
Header / Exhaust Clearance
There are several different bellhousing configurations for the 4L60E/4L65E transmission. The earlier
models (1993-1996) have an integral bellhousing identical to the 700R4. In some cases, the dust cover
mounting ears will have to be cut off to accommodate header collectors. This can easily be
accomplished with a hacksaw. The later models (1996-later) have a fully circumferential, bolt-on
bellhousing. It is important to use the correct bellhousing for your application. The LS1-style
4L60E/4L65E transmissions have a unique bellhousing and input shaft. These types are not direct
replacements for the non-LS1 applications.
Some headers will interfere with the starter hump on the bolt-on bellhousings. It may be necessary to
either dimple the header or cut off the starter hump.
