converting 4hdd to a 5hdd running for about 3 months

[peter1]

I am having a problem with the my level 3 dash speedo not working or how average speed and and how much fuel in L per 100km showing the amount hasn't changed this happened about 5 days ago i have tried a level 2 still the same problems. I have changed the speed sensor. What i did when changing the 4hdd to a 5hdd i took the valve body and added the lock up solenoid then put it back together. Then i tested it and the speedo and everything was working fine until about 5 days ago. I am able to still drive the car around and it changes gears fine.

all fixed found out one of the nuts and threads had snapped and it look like it was holding i used the multimeter test and showed they was a break in the in current and it was the ground one when you put the speedo needle and face off the speedo it got printed on ground
