Before installing the new pan, they should apply the new gasket and any required sealant according to the specifications. Carefully attach the new transmission pan and securely fasten the bolts.
Step 6: Refill the Transmission Fluid
Using a funnel, they should refill the transmission through the fill tube using the recommended type and amount of transmission fluid as specified in their vehicle’s manual.
Step 7: Test Drive
After everything is securely placed, a short test drive helps ensure everything is in working order. They should look out for any unusual noises or fluid leaks.
