Prior to having a tow truck come and pick up your motorhome, find a friend that may have a scanner to scan the trouble codes in the transmission, may be an easy fix.

OD light flashing. means that a problem has been detected in the trannsmision . Mine started doing it once in a while. I ignored it to long. Just lost the tranny last week!
I suggest taking to a tranny shop and see if they can pull the code. It may be something minor, that can be fixed now.
please do explain, dont work.
it never engages
or hunts.
or lamp flashes (some early cars , flash it for failure)
The PCM on most 99 cars controls the engine and tranny all in one box. and can do many things, wrong, to cause OD to fail
even Limphome, mode. (btw tranny has its own limp mode too)
why not scan the PCM and pull out the DTCs for tranny
P07xx or?
that be first.
the PCM will in fact skip OD (top gear) if it thinks it will overload
the engine or tranny is malfing. (slipping and other checks)
the newer the car , the more of that protection is going on....
saving car from driver actions.
That happened to my old truck, an 04 dodge, and I said to myself " chancery, old chap, this must mean a new transmission" , I was mistaken. The solenoid pack in the tranny was bad. I had that replaced for a fraction of the cost of a new tranny and never once had another transmission problem.
When the OD light flashes in this truck it means a malfunction has occurred in the transmission, it usually will be due to excessive slippage of the transmission based on the signal of the input and output shaft speed sensors. Here is what you need to do is have the Transmission Control Module tested for the fault code or codes that was stored when the light starting flashing, it is doubtful the valve body is the problem based on my 30 years as a Ford dealer technician.
Hi Mamaberta7,
The OD light flashing is something you need to have checked using a scanner. Since this trans. was recently rebuilt,you want to get it checked soon. The transmission can default to full line pressure and this can cause damage. Also if the unit isn't locking up, it can cause the transmission to overheat.
The airbag light on and the horn not working are probably tied into the clock-spring. This is the most common concern with the symptom you have. Again,you can have the code pulled to confirm the problem or you can use a DVOM (Digital volt/ohm meter) and check for continuity through the clock-spring. If you want to check it yourself,let me know and I will get you the steps to down the system and the wiring diagram.
If you have any other questions,drop me a line. Thanks,Chuck
The flashing OD light indicates there is a problem in the transmission control system. When the Transmission Control Unit detects a malfunction it will flash the OD light and store a Diagnostic Trouble Code (DTC) in the computer. You will need to have a Ford Dealer pull the codes and determine exactly what is wrong.
I wish I could be more specific, but there are about 120 different reasons for the flashing OD light.
Its a faulty sensor switch on your brakes master cylinder. It leaks brake fluid into the wires that are plugged into it and causes a short in the circuit, resulting in a blown fuse that controls the AC, odometer, speedometer, cruise control, and ABS light to come on. This problem can also cause a fire. The fire can occur even when the vehicle is off. To fix this problem go to this URL - http://www.fordwindstarrecall.info/
