The transmission overdrive relay often fails, preventing the transmission from shifting into overdrive. In some cases the Overdrive light may stay all the time or not come on at all. The relay is located behind the center console, just left of the glove box. Before replacing the relay it is crucial that the wire leading to the overdrive solenoid is inspected to ensure it isn't shorting out on the transmission case. Failure to check this may lead to a failure of a newly installed relay.

Recently I was driving on the freeway, like I normally do. And my rpms just shot up out of no where. This freaked me out because I was going about 75. And since this problem has occurred, I've noticed my rpms are about 500 revolutions higher than normal, which doesn't allow me to go past 60 on the freeway anymore. I feared it was transmission problems. I saw in the previous comments that often times the overdrive will be off, and that goes the same for my 91' beast. It just feels like my car is always forced now.
