Have 05 F150 5.4L. Pulled the transmission to replace the flexplate, because it was bad a chewing up starters, but after getting everything back together and started. Truck won’t budge. Checked the fluid. All connections and still nothing. So pulled it again to see if we missed anything and still nothing. Ran perfectly fine on it way to the shop but any help would be appreciated

 

Are all the bolts back in;
a) flexplate to crankshaft
b) flexplate to torque converter

Any loud banging noise?
Did you manage to break the input shaft?
Did torque converter get put in without catching the pawls?
Drive shaft connected?

 

One post, so descriptive, nothing about starter action, just "Truck won't budge". What does that even mean?

 

Truck starts up fine. Changed the filter and fluid. Let it run for 30 min before checking the fluid to make sure it was at optimal level. Triple checked all the connections. Have all the bolts back in. When you put it in gear, the rpms drop a tad like it’s loading up but nothing. Even if you rev the engine. Can select neutral and goes into neutral. Manually put the transfer case into 4h & 4l still does nothing. Driveline was put back in the same way it was taken out. Doesn’t make any odd noises or anything. Even pulled the transmission again just to make sure. Even put the Matco professional scanner on it to see if it was throwing codes and nothing. It’s almost acting like not enough fluid. Check the TC and it’s in the correct spot

 

Whose trans filter did you use?

You did use only one filter seal?

How much fluid went in?
