I have had problems for months. I finally spent the 178. 00 for a new TPS. It worked ok for a day or two. Then started to search for overdrive and t. c. lockup. The trans temp lite has come on and off for months. I got one yesterday a put it in. That did it !!!! Shifts like new. I think I will keep it . Thanks to the last issue of TDR in the tech topics. Made me think that little lite was related to my problem . Larry.
