transmission issues
 

when my truck first goes into overdrive the transmission tries to downshift almost like the converter is locking and unlocking. it only does it between 45 and 55 mph when I am driving easy. once I am over 55 mph the truck runs fine. it did this once before a couple of times then went away, now I cant engage my overdrive until I am over 50 mph. has anyone had this problem before and how did you fix it ?

I have had this problem and it was fixed with a BD noise filter, it helps take the noise out of the alternator signal that the TC reads as GO CRAZY. Just make sure when/if you install this that you go buy a can of battery terminal cleaner and sealer. This will solve the issue. To install it takes about 10-15 minutes.
