First of all, to service an automatic transaxle, change the fluid and filter at recommended times. For 40TE and 41TE transaxles, drain the fluid, clean the pan and body, replace the magnet and filter, reattach the pan, and refill with fluid. For 62TE transaxles, follow a similar process but use specialized tools to check the fluid level. For 948TE/9HP48 transaxles, which are "sealed for life", only change the fluid if there's a leak. Always check fluid levels at the correct temperature.
