Manuel down shifting power lose
Hi everyone I have been looking all through the treads and have not found my problem.
So here goes I have a 2005 King Ranch, the transmission has all the updates on it ( rebuilt a year ago ). The problem is when I manually down shift to either 2nd or 1st the engine seams to derate (loose power)! As soon as I put it back in drive the power returns.
I bought this truck used three years ago and the problem has always been there. Tired of dealing with it and would like to get it fixed. Any help would be greatly appreciated!

I do a lot of off roading in the Rocky Mountains here in Colorado to get to lakes and streams and prefer to keep it from shifting when I need to.

So to answer your question, I am not sure why the power changes. But, I can tell you that when manually shifting the transmission uses different components. The low reverse band applies in manual 1st and the OD band applies in manual 2nd.

And that is a good and real reason. That is what the ability to manually downshift is actually for.

I have this same issue with my 2004 f150, fx4. When I shift down to 2nd or 1st, then engine acts like it goes into "limp mode". This is a feature of the 5.4, that will try to protect the engine upon overheating, low oil pressure, etc. I have driven other f150's with same setup that do not have this issue. They have the power you would expect. No one understands this when I ask for help. I really get a chuckle out of people who say " why would you down shift?" Ha ha! So, I feel your pain bro. If you ever find the solution, please share
