My 2000 F53 V10 with Ford 4-speed automatic transmission has a overdrive on/off button on the end of the shifter. I tap the button to disengage the overdrive when I need engine braking. This weekend while descending the long grade between Kingman, AZ and Laughlin, NV I tapped the button to disengage but no downshift occured. The light on the end of the shifter came on but the engine RPM's dropped to zero. I slowed and dropped out of Drive to 2nd and the same thing happened...no engine braking...I'm free-wheeling! Using my brakes I was able to descend slowly and safely. When I reached level ground I came to a stop and then started again. I expected 2nd and 3rd gears to be gone but to my surprise the tranny hit all the gears on the way up to cruising speed.I tapped the OD switch and free-wheeling again! My transmission is working fine but I no longer have any engine braking. Naturally I'm just months over the 36 month factory warranty and all repairs will probably be on me. Has anybody had any similar experiences that might help me take the next step? Tim Ryerson Prescott, AZ 2000 Tropi-Cal 6351 F-53 1999 Honda CRV Stowmaster 5000 SeaEagle 395 ps

Tim I would suggest a quick call to Fords 800 number and see what they tell you. Good luck

Do you think the Ford Help Line will really help me or will they shuffle me off to a high priced Ford Dealer Service Dept. for high priced low quality repairs? This website has been more help to me than Ford has ever been. It was this board that told me that Ford had a secret warranty on in tank fuel pumps in my last motor home. FREE was alot better than the $750 dealer solution! The Ford helpline will be my LAST RESORT! Thanks though for your suggestion...I don't mean to be unappreciative.

I have the smaller version of the Ford tranny in a Mazda PU. I also had some problems with the OD and the button would not cure it. I found by pulling the fuse then reinserting it my problems went away. When towing I never use OD as my co-worker had his tranny go out completely by using it while pulling his boat. tfjones God grant me the senility to forget the people I never liked anyway, the good fortune to run into the ones I do, and the eyesight to tell the difference.

Tim - A couple of thoughts:
1) My '95 F53 chassis manual says that if the chassis battery has been disconnected it will take several miles for the computer to reprogram the tranny. I don't know if this is true for your newer tranny, or if the OD would be affected, but if you did have a power interruption it may be something to consider. Perhaps pulling the fuse, as tfjones suggested, would re-boot the computer and solve the problem.
2) Again, you have a newer tranny, but on my E40D the shift lever light goes OUT when shifting out of OD.
BTW - Most of our travels involve some very big mountains and if my tranny started freewheeling, you'd likely find me plastered on the bottom of some deep canyon. This is definitely a safety issue and one that you should discuss with Ford.
Good luck. - Dave This message was edited by Dave_Peters on 9-5-03 @ 10:30 AM

Tim,
A question to add to the confusion; isn't that OD light also a "Check Eng" light? If so, it's probably popping a code and most any shop can read the codes and tell you where the problem lies...That is if you don't have a code reader yourself....Good Luck... Happy Motoring, Butch Nancy Lake, Alaska

Hey Dude, In the first place that "OD" light isn't really for decelerating down hills, it ingages and disengages your OD gear in your tranny. If you want to gear down when coming down a grade simply put the gear selector in the next lower gear, it's the same thing. You're just disengaging the OD. When was the last time you had your transmission serviced and how many miles do you have on your coach? I "think" and don't quote me on this, that the OD button activates an electric solenoid engaging and disengaging OD in your transmission.

Butch, Dave,
Thanks for your feedback !
The light on the shifter will light up when the button is pushed and reads " OD OFF " with a steady glowing yellow light. The manual says that the light will " blink " if there is a tranny malfuntction and if it is blinking to go directly to the nearest Ford Service Center (pardon the oxymoron). My light is not blinking but is a steady light, which is normal. Dave, you're right..this is a safety problem and I hope Ford sees it that way. With just three months over the 36 month warranty and only 36,020 miles on the odometer I hope they get involved in the costs to repair. I was hoping that someone on this BBS had experienced exactly the same problem and I would be better armed to deal with the factory/dealer techs.

Neil,
Thanks for your response. I agree with you but this is the puzzling part. I shifted the transmission shift lever from Drive to 2nd on the selector after the free-wheeling problem was first noticed and it did the same thing as pushing the OD on/off button on the end of the stalk, namely it free-whelled also. In other words I had no means to downshift for engine braking. I DIDN'T shift into 1st so I don't know if I would have gotten low-speed braking.

Do you get any engine braking when in OD? In other words, does the tach stay up in the teens and then drop to idle when you push the switch or does it stay at idle all the time you are descending? How about if you climb the hill with OD off. Does it brake descending then? Anything with a computer can get confused. I would try to disconnect the battery for a while and then reconnect. This will reset the computers and solve any programming glitches. When all else fails, check the fluid level.
