SITUATION
If repairs involving the removal and installation of the engine become necessary, the transmission must always be removed first as outlined in the
repair manual.
Note:
Always support the engine and transmission using the appropriate special tools to avoid automatic transmission oil pump damage due to engine and
transmission "sagging" at the mating point (engine block to transmission bell housing) before the fastening bolts are removed.
Before reinstallation of the transmission, the dowel sleeves must be removed from the transmission bell housing and installed in the engine block as
outlined in the repair manual and shown in the illustration below.
Note:
The transmission bell housing and engine block mating surfaces must always seat flush with each other (dowels seated in holes) before the bolts are
installed and tightened to avoid damage as seen in the illustrations below.
Failure to follow the proper repair procedures will result in engine and or transmission damage due to engine/transmission misalignment.
Additional installation information can be found in "Transmission Failures Due to Incorrect Installation".
