My 2000 F-250 Diesel w/ automatic transmission developed a strange symptom yesterday. It would fail to shift from what I will call 1st to 2nd, however upon running the rpms to around 2000 and letting off the throttle and dropping the rpms to around 1000 it would shift up to 2nd. Additionally, 2nd to 3rd will shift as normal. I also determined that I could shift through the gears using the gear shift lever. I have taken the truck to 3 shops today and not one can begin to give any kind of an answer to the problem. They have all said it has no trouble codes when checked through the computer. If any one has any kind of clue I would like to know.

Hi guys, I'm looking at a problem with my 2000 F-250 SD 5.4 V8 ext. cab, shortbox.... the O/D light just started flashing. It is shifting hard going into 2nd and 3rd... sometimes in all gears. I just had the gem module replaced and both complete front brake calipers, right tye-rod end and the rotors... I use this truck as my main transportation and also to pull a 4 horse gooseneck trailer. Any idea if this is something that isn't got me to the "terminal/sell" line??

Whoops, sorry that is an automatic trans.

Thanks!

When the o/d light starts to flash that means that a code has been set and some of the trannys will go into a "fail safe" mode to save its self (gotta love electronics) take it to a tranny shop they should be able to help you if they cant .......find one who can becouse they have no buissness working on bicycles let alone transmissions
