Put a new transmission in now when you crank it up the speedometer says 80 and then when we're going it's going to 100 in the engines cutting off

Looking for why speedometre won't work

So I was trying to back my truck up over a curb and didn't force it too bad...I had the wheels turn and turned 4x4 on when I try to take off now it hesitates to takes off and the speedometer went out...also when I truck left and right it' sounds like rubbing and vibration everything was fine until I decided to go over that curb.

Speedometer starts at 100 Kim’s a hr

I have a 1997 f150. My Ac compressor locked up on it so I threw it on the dolly and pulled it home(not thinking) I changed out the compressor and on my test drive noticed my speedometer was not working. Could I have messed up my VHS by pulling it home?

When wrench comes on instrument cluster stops working and speedometer drops to zero and truck is in limp mode. Accelerates slow but still drives. What could be my issue. I may need to pull codes or go to dealership to have them pull codes. I don’t have the money to pay the dealership to repair so hopefully this is an issue I can fix myself

Speedometer not working odometer works till 1 shift then goes to dashes or goes out every thing else in cluster works

Rear Blinkers still work as do flashers. Removed dashboard panels around steering wheel replaced Speedometer and Tachometer display lamps with #39 long-life lamps reinstalled cluster. Went to store to get water, police stop due to taillight failure.

Speedometer stopped working, also odometer stopped and windshield wipers work half the time

My truck on cluster a green wrench appears and it loses its power when driving and it wont gain power when push on gas pedal also speedometer drops to zero and stays there. Sometime it will go off and go back to normal for a minute or 2 but right back to the same issue. I turn it off for a minute and it will real reset back to normal but five minutes later it does it again.

Lost tac speedometer water & trans gauge , all messages traction low fuel blue wrench, charging system , when the problem is on the truck still runs ok but if I turn it off and try to restart it won't restart but will restart now and then. Checked battery 12.8v alternator 14.5v with or without problem on.

Will not go lower than third gear will not go higher than 5th gear the speedometer will not work I have heard on the internet that it might be a transmission problem
