Does the Protege overdrive have a fuse or a relay?

The overdrive problem on a 1995 Mazda Protege is due to a failing spring in the end housing inside the transmission. If you replace the spring with a new or used factory spring the problem will re occur. You must use a revised version to permanently fix this problem. I have seen salvage yards advertise this overdrive unit. What a scam. Even the brand new factory unit will fail, so obviously a used one will also fail. You must contact a transmission shop, they will probably have seen many of these in their shop and will have the part number of a revised unit.
