Transfer Case


The model 207 (early vehicles) and 231 (late vehicles) transfer cases are equipped with an identification tag which is attached to the rear half of the case; the tag gives the model number, the low range reduction ratio and the assembly part number. If for some reason it becomes dislodged or removed, reattach it with an adhesive sealant. Late model vehicles may be equipped with an electronic shift transfer case, the 233 model. The MFI-Turbo is equipped with the Borg Warner 4472 transfer case.
