Hallo all there, I´m new here in the forum.

This site is great, the maxium site decated to TBird and Cougar.

I have a question.

I have a TBird 94 LX 4.6L, and I have problem, the indicator O/D OFF starts to flashing whitout any problem, my mechanic scans the car (specialist in Automatic transmisions) and doesn't detect a problem, my car don´t have any perseptible problem the transmision shift ok, only is the flashing indicator.

A friend tell me that this model of car, had this problem, he tell me that the tramsmision oil bar is too short and doesn´t marks the real level of oil, my freind give me a solution, that is to add 300 ml more to the transmision, and the problem will disapear, but isn´t disapear.

Any of yours have or had this problem.

Please help..

Tanks!!!

Welcome to TCCoA. I would post this in the drivetrain forum a little further down the page, but I can try and answer you here.

If you have a stock 94 trans., I'll bet that the intermediate clutches are getting burnt. I would check the color of the fluid on the dipstick and see if it's brown, or nice and red. Also, you would be best to do the following to that trans. if you would like to get some life out of it (maybe)..

J-Mod
24K Trans. Cooler
Flush and fill with Mercon V fluid
Change filter

I'm sure someone w/ more experience can elaborate and suggest a better plan of action, but that's my .02

I'm going through that w/ my 95 right now, and the cause is burnt up clutches and the one-way roller is on it's way out. New transmission time. Hope you don't have the same issue.

Also, I would try a search and use the subject line "OD flash". I know that some ideas have been covered before. Too many things could be causing it, so doing the search may point you towards something that rings a bell w/ your particular issue.

Good luck.

I also know that the OD light starts flashing if the tranny temp gets too hot.

The OD light flashes when the transmission throws a code. get the codes read FIRST.
Don't have any code, I tested on way with the specialist and connect the scanner, te O/D OFF starts to flash and the scanner doesn´t not get a code.

My trans is about to blow??
I'm too worried about this problem

Tanks for your sugestions.

Bummer about the trans, but if you intend to keep your car running, and possibly modify it, or at least restore it or keep it in good running order, it could be kind of a blessing in disguise.

The '94 automatic transmission are exceptionally weak and prone to failure. Later model transmission were much improved.

So before you sink money into rebuilding your '94 trans to it's original condition consider the option of getting a low mileage used 1999 and up replacement 4R70W transmission.

I picked up a 2002 trans that came out of a Mustang GT for $600 from Greenleaf, and lots of other guys on this board have found similar units for around the same price. I had mine inspected and modified by the guy who designed the transmission origianally and when he opened it up he said there it showed no wear at all. Greenleaf guarantees their parts, so if there is a problem you send it back and they send you another one. The price includes shipping BTW. You can order them on-line, but I would suggest calling them and let them give you some options. Timb on this board has bought engines and a trans from them and has a contact. Send him a PM and he'll give you his name, but anyone there can help you locate a trans.

That's only one option. Their are other sources for these transmissions, and I've seen guys post that they have found 99+ 4R70W's for a lot less than $600.

You may ask if you can rebuild your transmission to the newer specs. The answer is "yes", but it is not cost effective. The additional parts along with the rebuild parts will cost more than the trans is worth when you're done. For instance, they upgraded the valve body. That part alone is over $200 at a very discounted price from Dan Newman. Add in the other parts and labor, and you are way over $600. I've heard guys have paid as much as $1000 to get these transmissions rebuilt at a shop. Maybe your guy will give you a break on labor, but the parts are expensive, and if you rebuild it to the way it was, it will just fail again eventually. The one in my '96 T-bird failed twice in 60,000 and the one in my '95 failed at 30,000.

If you want to educate yourself on these transmissions, go to the tech articles, click on "transmissions" and go to "Transmissions 101". The article is written by the guy who inspected and modified mine, and designed the trans originally.

When you get around to Chapter 13, I think, the article describes some modifications you can do to improve performance and longevity of the trans. Around here we call it the J-Mod. It is worthwhile to do these modifications. With a 99+ trans, you have a head start, alot of the parts are already upgraded.

Properly modified these transmissions can support over 500 hp at the wheels. In stock condition the early models are prone to failure. An unmodified 99+ is a good bet, or you can choose your level of modification to suit your application.

Good luck

My OD light started flashing usually if I stepped on the gas , I would then pull over turn the car off wait a few minutes and it would not flash again for weeks ( until I forgot and stepped hard on the gas again) about a year after it started flashing almost all of the time , by then I realized my tranny was on its way out , I took it to a transmission shop that only does Ford transmissions had it rebuilt( $750.00) changed fluid to mercon V and it works great now , next project is a heavy duty oil cooler
