#1) Low or dirty transmission fluid #2) Wire/circuit issue shorted to power or ground #3) Failed torque converter clutch (TCC) solenoid #4) Failed TCC assembly in the torque converter.....

Since Transmission has been rebuilt I would strongly suspect the TCC solenoid and/or its wiring...When transmission was rebuilt did the TCC get replaced? If so, due to being intermittent, Check the TCC plug (both female and male) for bent or dirty contacts...also insure you have close to zero ohms of resistance from negative battery post to transmission case...A poor ground will cause a problem and be at times...saailer

SOURCE: Having problem's with my 98 Ford Windstar

Check  transmission fluid level first. Make note if the fluid color is dark brown and smells burnt you probably have a serious problem. If fluid is full, you probably have pump failure. Trans will need to be overhauled or replaced.

SOURCE: ABS and brake on 2001 Ford Windstar come on randomly

Do you mean the van is actually braking like a Starsky and Hutch move or that the warning lights indicate that they are on? If its lights then you may be low on brake fluid. Maybe a module leak

SOURCE: 2000 windstar airbag light is on on dash and horn

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

Have 98 ford windstar van when trans shifts from first to second it feels like someone hit you in the back other wise it works good is it an easy problem to fix would a fluid and filter change cure it?

Get someone to put a OBD tool on it and get some codes and look them up, but sometimes it could be dirty fluid filter like you said. I hope your tranny is not slipping.

I have a 98 ford windstar, and the tranny went out in it. so i went to a junk a yard and bought a 98 ford windstar tranny from them. my dad took out my old tranny that was in the van and said that both...

You answered your own question.
They don't look the same,so why not return it.

Having owned a Trans Shop, I will tell you, getting a used trans will be the worst auto repair decision of your life.

Your buying something most likely worse than your pulling out of yours.

All Auto Trans need to be perfectly super clean inside to work well.
80% of all failures are due to not changing the fluid every 30,000 miles or two years.

Your best bet is what is called over-the-counter. You drop off your trans at a shop,they rebuild it with the latest updates and you install a rebuilt converter,adding a quart of fluid first.

All transaxles,especially van type ,don't hold up well. Not many see 100K.

You never want to have a front end collision with a van and expect your quality of life to be very good afterward. A larger SUV is safer and rear wheel trans,hold up pretty well.

98 windstar overdrive flashing

i recommend using a DTC reader to check the codes 1st but i suspect the transmission range sensor. it gives out due to a poorly placed master brake cylinder. the switch leaks and causes electrical problems with the TRS and other units connected in the wireing harness directly below the brake pressure switch.

98 ford windstar has battery light on put new battery in and its still on. I put volt meter on battery while car is running and its reading 16 volts

The problem is the voltage regulator is bad. However the regulator is almost as expensive as a rebuilt alternator so unless the alternator as been replaced recently I would suggest to go with the rebuilt alternator.

Surging while driving

DO NOT waste your money on tranny solutions!!! I have a 1998 Ford Windstar. About 2 years ago I started noticing a strange almost shaking, jerking serge type of activity when I would get into the "mid-range" (30-50) on the speedometer. I took it to a very trusted mechanic. After about $2000 and several different "tranny solutions", I thought the problem was fixed until about two week later when it suddenly jerked and sputtered AGAIN!! Don't waste your money on tranny issues. (by the way.. my van has also recently had a new tranny put into it and it STILL HAPPENS)
