I recently purchased a 2006 Fx4 level ii, 4.0litre automatic. 28.5K miles on it. got a good deal and like the truck except for this one thing...
When i put it in first gear to decend a hill why does the gear not hold me back? It almost seems like it is in neutral. I would think that it is a mechanical defect but my work truck, an '05 4.0 auto does the same thing.
I have been driving a '93 4.0 5speed forever. You could drop that thing into low four without locking in hubs and idle up or down most anything. sold it now i am in this truck. 99% of the time it is no big deal but that 1% can be important.
Here is the example: Just on the Moki dugway in southeastern Utah: http://www.google.com/search?q=moki+...w=1252&bih=589
Put it in 1st to hold us back and it would roll pretty freely down the hill and it seemed that the rpms wouldn't really react as well. It wasn't scary with just the truck, but if i were pulling a small trailer it would scare the crap out of me. I have tried putting it in 4low to see how it would react and it still rolled pretty freely down a hill. needing 4wheel in the woods and riding my brakes seems pretty silly to me.
any thoughts out there?
