Use of GM 4L60 Transmissions require SIGNIFICANT modifications to transmission tunnel!
The amount of modifications varies depending on which 4L60 you decide to run. The earlier transmissions with the integrated bellhousing require less work than the later transmissions with the removable bellhousing.
No fabrication is required for the install and all of the structure under the dash can be retained. The dash does not need to be removed. The trans tunnel requires hammering in the transition area where the tunnel area meets the bellhousing area and where the bellhousing area meets the firewall. This is the area where the amount of denting will vary on which trans used. Additionally, the trans tunnel will need hammering along the sides around the bottom for clearing the sides of the trans pan. Lastly, the actual mounting point on the car will need to be cut on the passenger side. Please look at our 4L60 trans mount, and you will see that the passenger side of the mount only uses 2 of the three mounting holes. The mount location interferes with the trans pan which is why it needs to be cut out.
