interesting example.....my tranny did go into a self protect mode, as described my the mechanic...shifts really hard...it was pushing the pressure up to keep other things from failing I suppose...now it shifts puuurfectly....albiet $2500 later.... For example automatic transmissions have a "limp-home mode". When the conditions indicate an error that's not specifically recognized, the transmission typically goes into 3rd gear and stays there. (The rationale is that you can go wherever you need to go to get it fixed in 3rd gear.) --------------------------------- Get your own web address. Have a HUGE year through Yahoo!
