Slightly dumb question but.....

What would probably happen if I put too much tranny fluid in?

I had a leak at the line fitting coming from the radiator and replaced it. Everything was fine. Today I get bellows of smoke from under the midsection of the car while driving and I notice spots on the driveway of my mom's house (light colored concrete). No clue as to where the leak is coming from at this point.

The exhaust is hot cuz I jut got home from a 1 hour long trip and It's freezing outside. While in OD the tranny slipped twice. It corrected itself once by just wiggling the shifter (column) and the other time I just took it out of OD altogether. I stopped for gas and checked fluid level (high) and pulled off in OD with no problems.

Another cool thing was ....
I was going down a straight road tonight (speed limit 35) and was cruising. Let off of the gas at 38 mph and it climbed up to 40mph all by itself over the course of about 3 miles. WTF?!?!?!?!?!?!?

I don't have alot of experience with these cars, but if the fluid is overfull, it's going to want to find a way out.  I would think that either the front or rear tranny seal would start to leak.  I would get the car up on jack stands and wipe down the tranny.  Next, I would check the fluid level and if it is not overfull, drive the car and check again for leaks.  Make sure the tranny is hot and is checked hot with the car running.  If you need to remove some fluid, you could use a syringe and a long tube to drain some fluid from the dipstick tube.

As far as slipping while in OD.... maybe a band adjustment or perhaps something electronic.  Like I said, I don't have a lot of experience with these cars, yet.  You may want to check the color and smell of the fluid.  If it's dark and smells burnt, your tranny bay be getting ready to check out on you.

As for the cool thing - psuedo-cruise control...Not sure there.  Not normal though and I'm sure there maybe someone else more knowledgeable. 

Good luck and let us know how you make out.

I'm gonna siphon some fluid out first thing in the morning. I just happened to buy a pump the other day to try and steal gas from my other car (new cars suck). IF it wasn't so dang cold outside I would give the underbody a good scrub but that would have to wait. The overfill could explain the leakage. The fluid is still red as the day I put it in. The transmission treatment I put in could be saving my butt right now.

your perception of over full is what you did not indicate.

my AOD is always about an inch over full. Its always been like that and it does not complain or leak.

just coasting a long and the mph increases must mean the road was slightly down hill and you just did not know it.  The air is thinner in the winter so you'll have less drag but three mph is a lot.  maybe you had a tail wind , ive had wind push me along before.

presure wash off the bottom of the rear engine and front of the bell housing.  next presure wash off the tail shaft of the tranny.  drive it until it dries out and then park it.
next, presure wash off the pass side of the tranny where the lines go into the tranny.    The same fittings up at your radiator reside there as well.  If you finagled a starter in the car recently, the can be disturbed due to you moving them out of your way.  If you had to bend them  a little, they may not be sealing along the plastic insert in those quick nut fittings ford put on these cars.

I wish they kept those fittings simple like JIC fittings or flair fittings.

look for the newly collected flud drips.

find out where the leak is located and then act on that.

To much fluid in an automatic transmission makes foam.
Air bubbles do not handle pressure well, nor do they cool
the tranny.

There are only two tools you will ever need:
1) WD40
2) Duct Tape
If it doesn't move and should, use the WD40.
If it moves and shouldn't, use the duct tape.

sucked out a lot of fluid this morning. the levels are a little high still but close to the hatched area.

God I hate the smell of tranny fluid.

I'll proceed to cleaning and finding any leaks this weekend.

Thanks guys.

Aren't you supposed to check the tranny fluid level while the engine is idling?  This is the case with most cars.

Your level won't appear high when the engine is running.

The car needs to be running and warm, sit in the car and shift through the gears spending a couple seconds in each position. return it to park, pop the hood and remove the dip stick, whipe, then re-insert it to check the level.

To clean the bottom side of the car go to a car wash, spray the bottom with castrol superclean, then hose down. it will be squeaky clean.

your "suppose" to,, but,
i have over the years gotten use to where the level is when cold and not running compared to warm and running.  So,,, i guess in theory you dont have to.

all i know now is that if my dipstick says about 3/4 inch over full with a bone cold motor not running,, its good to go.
