Maintenance - Transaxle
General
The user manual has detailed instructions regarding inspection, maintenance and oil changes. Hill recommends using Redline 75W140
Bellhousing
It’s imperative that all screws that mount the rods ends use a washer between the misalignment washer and the bellhousing. Otherwise the misalignment washer will be bridged across the recess machined into the bellhousing. The left and right sides are symmetrical and the part quantities below include both sides.
