Transmission Disassembly: Notes
NOTE:
Beginning at start of production for all 1996 models, some 4L60-E transmissions were built with a bolt-on bellhousing. Design change will make 4L60-E transmission more versatile for a wide variety of engine sizes. Bolts securing bellhousing require a Torx-Plus 50-IP bit for removal. Bolt heads will strip if incorrect tool is used during removal. Transmission case has a totally different casting design for bolt-on bellhousing. Oil pump body has a machined ring added to front of pump body to center bellhousing on installation.
