Query: Perfect aftermarket replacement

The OEM transfer case motors on S-10 blazers have a design flaw that allows grime and water to enter and eventually cause them to malfunction. This prevents you from switching from Auto 4wd, 2wd, 4wd hi and 4wd low. This part replaces the oem motor and also has sealant that prevents the same thing from happening again. This installed easily and is working perfectly. Note, if you haven't replaced one of these before, read the included instructions before beginning. The motor is set to the neutral position so you need to put your selector in neutral before removing the old motor and installing this one. If you can't, there's an alternate procedure to follow.
