Full Answer

Locate the transmission pan, and place the drip pan directly underneath it. Loosen bolts holding the pan on slowly, taking care not to let fluid drip on your face or in your eyes. The fluid starts draining as soon as the seal of the bolts is broken. Remove the bolts, the pan and the gasket seal, allowing all of the fluid to drain into the drip pan. It is a good idea to inspect the waste fluid for debris or metal shavings that can indicate a potential transmission problem.

Inspect the gasket seal, and replace it if it is damaged. Coat the gasket with a thin layer of JTV sealant, and reattach the transmission pan, tightening the bolts by hand. Use a wrench to finish tightening the bolts evenly. Remove and replace the filter; tighten the new filter in place according to its specifications. Add the new fluid until it reaches the correct level on the dipstick.
