Locate the fill port. It is the socket-head cap plug
on top of the transaxle casting. It is not the black
cap on top of the plastic catch tank.
7.
Clean the area around the fill port.
8.
Remove the plug using a 1/4” allen wrench.
See Figure 5.62.
NOTE:
If the transaxle is draining slowly, this will
allow more air to enter the housing, speeding the
draining process.
9.
After the transaxle has drained completely, rein-
stall the drain plug.
10.
Fill the transaxle with .600 to .632 gal. (2271 to
2391 ml.) of 20W-50 engine oil that has a mini-
mum API classification of SL, and a minimum
rating of 55 SUS @ 210 deg. f. (99 deg. C).
11.
Purge the transaxle. See Figure 5.63.
