Was driving car was doing just fine and the
o/d light starts blinking.Pulled over checked

stared it back up light was off. When I go to
pull out the thing was REALLY Slow at shifting
between 10 & 20 mph then runs good when I get to about
45 mph the light will start blinking again. My
beginner driver hit a building the other day
could there be something knocked lose that would
cause this? DH is in the construction business
and is working out of state. Any information

Welcome onboard.

Doubtful accident is related unless it caused loss of fluid; any loss is cause for physical check of transmissiom and fluid hoses to cooler at rad.

You can do a search on o/d light, but I'm afraid there's no definitive answer I've seen to-date.

My car does this as well, though getting your transmission rebuilt is probably not the answer, as mine was rebuilt just last year and is still under warranty. When I am on the highway, I drive for about 15 minutes, and the OD light strts flashing. This does not happen when I am driving around town. When I pull off of the highway, my car shifts really hard for a while, eventually going back to normal. I have never encountered anyting like this, but it's good to know that I'm not the only one with such an odd problem.

A fluid change may help but the flashing OD light usually indicates more serious problems. When you have the fluid changed make sure to use Mercon fluid. Some have had some success with adding some Lucas transmission conditioner to the fluid for smoother shifts. There is also an elecrical signal connector on top of the tranny that should be checked and reseated.

I had the exact same problem it took me a whole summer and ford a converter, two transmissions, computer, and speed sensor to figure out whats wrong. Your wires are throwing your speed sensor off. Either you just changed your wires(hi performance type) or your wires are bad. But I'm almost sure of it. Your speed senor thinks your car is going 50 mph at idle. Thats with all the shifting off idle and low speed and such. But stock replacements back on it.

I hate to tell you this, but the same thing happened to me back in October. Turned out my torque converter went out. Had to have the tranny rebuilt. Runs fine now.

I had this problem two yeasrs ago. The o/d light would blink and it would shift hard into second. I had the tranmision flushed out, and it went away. about 20,000 miles later and it's never happend again .

what happens when it goes out?.........my light blinked the first of this month......changed fluid ,& it's been working well since......if it's only got a couple month to go , maybe I better unload it now...

when it goes its BAd mine strated that and now i have no tranny with all sorts of broken stuff. but hey look on the bright side order your self a shift kit and a nice new upgrade turqurconverter and wha la a whole new tranny at the same price they will charge you for the same thing you have know... I think..... i am in the middle of doing mine.
