Attention: TDR Forum Junkies 
Just wanted to thank those who posted in other threads I've been watching regarding overdrive problems. My '93 was cycling around 50; had to find the "sweet spot" or floor it to reach overdrive. After some reading I decided to pull and clean the TPS. Only problem was no obvious grime, so thought I was wasting my time. After cleaning the contacts, drenching in WD-40 and rotating the postioner, and ending with dielectric grease on contacts, everything works GREAT! Hard to believe I saved over $300 today. I love you guys
