Flushing clean the oil cooler
When replacing the transmission, the oil cooler must always be flushed through because there may be particles in the oil cooler. See: Oil cooler, flush cleaning .
Check that the transmission and engine mating surfaces are absolutely clean.
Also check that the guide sleeves towards the engine are in position and are free of faults.
Lubricate the holes in the transmission (for the guide pins). Use a little grease.
NOTE:
This only applies if replacing the transmission.
Slacken off the bracket screws for the bevel gear - chain housing so that they can be moved slightly. The bracket is on the cylinder block.
