Changed tranny filter - Speedometer died????

[BigRed]

Ok, I changed my tranny filter this weekend because my TH400 was slipping in reverse when cold. Well, I got the fluid changed out and took it for a test drive and my speedometer didn't work any more. Tranny still slipped too!!!!!

So, can anyone tell me what could have caused this? I didn't even get close to bumping the speedo cable. All I did was remove the tranny bolts, remove the pan, replace the filter, and put the pan back on.

Thanks for any help.
