Transmission Fluid Capacity

For manual transmissions, the correct fluid level is to the bottom of the fluid fill plug opening. The fluid capacity will vary, due to the angle of the transmission, with the vehicle. For automatic transmissions, see the Allison Automatic Transmission Operator's Manual for fluid check and maintenance information.
