My speedo just started acting funny , basicly it reacting really slow, for exzample, i can floor it and I know ill hit 40 mph before my auto trans shifts but the speedo will be at 30 or 35 then i come to a complet stop and while im sitting there im watching the speedo , and still waiting for it to finally reach zzero. Has this happened to any one and its not the vss(vehicle speed sensor) because i replaced it yesterday and its still reacting slow.

Beware the Rouge Dragon.
mine does same @!#$... and it twitches at high speeds.. new vss new cluster duno.. tranny i guess
My cluster resets itself while driving sometimes
I want to share something with you - the three sentences that will get you through life. Number one, 'cover for me', Number two, 'oh, good idea, boss', Number three, 'it was like that when I got here.'
well im going to try to more reshearch, but wow this is crazy stuff. the car is paid off and now this happen the same month . So do you think the trans is goofing up?

Beware the Rouge Dragon.
i dont know about yours but mine almost has to be, although it shifts perfectly i duno ive checked the vss, cluster and vss wiring
I thought it was because the CPU tells the speedo what to do, so you get an average speed over time instead of an absolute speed. I am going to hook up my GPS again and find out how fast or not fast I am going like I did in my Civic, when I realized it read 5 too fast.
