I am having problems with an overdrive relay. I replaced my transmission and with it came the addition of the overdrive relay which worked fine for quite awhile but now it isn't. I replaced it once with a used one which worked good for even shorter but now is failing.

Situation is as follows: drives fine down road then kicks out of overdrive. I have the relay sitting out to fix problem by either moving plug around in it or what usually works best is tapping the relay against something. Then and only then will it kick back into overdrive. Any suggestions - what I am wondering is if I get a new or used one will it work for awhile and then be doing the same thing? O-ya it does seem to get a little warm, is that normal or not? Maybe I have an electrical problem.

Thanks - Noel
