i have a serious problem that just started happend today!

i was sitting in a parking lot and i put it into reverse and i went about 4 feet and stopped just revs up in reverse now, so i put it in drive and continue on home and it is slipping and jumping in and out of gear and i can only get it to go if i real gas it . by the was the truck is a 5.4 auto reg cab and has 34k on it

anyone have any suggestions?!?

 

ttt-



the truck will drive normal then statt jumping outta drive then go back to normal , while the reverse doesnt work at all now!!

 

my old auto did that and come to find out there was a dent in the tranny pan that was causing it not to go into reverse.........cheap fix if thats the case...........good luck

 

thanks for the reply does anyone else have any other opionions on what coudl cause this??

 

I don't know too much about tranny's but I do know that these are electronically controled (for the most part)

If your fluid checks out I would try re-setting the pcm to see if that helps.

This is a common low fluid or air in the fluid concern.

Last but not least do a search in the tranny forum.

 

ttt-i reset the computer and checked the fluid. still no reverse its like neutral and when it drive it will just hop in and outta gears at its own will.......


anyone know ford trannies??

 

If you have normal fluid levels (as per the dipstick), I would take the truck in to have the pump tested. It's obviously incapable of delivering the hydraulic fluid at sufficient pressure.

An electronic problem would put the tranny in "safe" mode, and you'd have reverse and 1st/2nd gear. Hoppoing out of gear is a fluid pressure or fluid blockage issue. Either way, you need to see a transmission repair shop. The auto. tranny is one of the world's most complex mechanisms...do NOT screw with it on your own.

Typical of a broken sun gear.

I would concur w/ moose, most trans shops will do an inspection relatively cheap. Prob. need to pull the pan and look for debris. Could be simple like the filter is fowled not letting enough fluid up to the pump or as bad as the pump is failing. I would bet on something mechanical from your description and the fact that you don't have a trouble light.

 

the broken sun gears re[ply scares me as it sounds expensive,thanks for your replys im going 2 take it to a tranny shop and see what they come up with hopefully its sumthing cheap ..

 

Drain the fluid through a filter, then take off the pan, if theres a lot of metal shavings or bigger pieces then your in trouble. If theres just a little bit of shavings then your alright and its probably electrical problems.

 

check the trans fluid/oil
and check the shifter linkage at the trans and in the colum
also turn your key on and off four to five times then leave it on the check engine light will flash count the flashes if it pauses re count the new flashes (5 flashes pause five more) is a code 55 then go ask the dealer what sensor it is good luck
