    I don't understand the "cup cover", "lubricate with fluid". Isn't this a normal automatic transmission with a dipstick and filler tube? And isn't it important to always check an automatic with the engine idling after warmed up? Also how does the fluid look? AFT is always supposed to look pink, and turns brown when bad.

    I hope this a an Automatic? If so when was the last time the trans fluid and filter was changed. Your filter mite be blocked and nothing is going throught the pump.

SOURCE: automatic trans slips 92 ford explorer

I would have the transmission check if you plan on keeping the car a long time. The lucas oil is an additive for the oil. The additive is making the fluid a little heavier and tricking the soleniods or clutch and bands with a different pressures.

This is a temporary fix. The transmission over time is going to start to slip more and more.

SOURCE: I have a 2003 GMC Envoy, trans slipping that I have been towing

Low fluid can cause slipping. (depends upon how low) Most manufacturers post "safe" tow speeds. These are generally ignored. (not good). I recommend towing with driveshafts removed and where driveshaft has a "slip yoke" you install a yoke from a scrapyard and wire it to the tailshaft so it stays in place (keeps oil in and dirt out) Although you can't just detach the tow-bar and drive, it eliminates any possibility of trans damage, since the transmission cannot turn. (most use oil from pump to keep gearsets cool...when towing, pump is not pumping and over time and distance it can damage trans internals.)
Hope your problem is just low fluid and not a rebuild...keep in mind what I said though.

SOURCE: no reverse gear - auto trans

Hi mjpgd,
I have the same problem on my 96 Pathfinder. I just spoke with a mechanic who said this is most often due to a knicked seal in the rear part of the transmission. The leak results in pressure loss, making the system reluctant to shift into reverse. He said the fix is replacing the seal. The part lists at approx $200 Canadian ($190 USD), but unfortunately it takes lots of labor. The whole transmission needs to be removed and taken apart to replace the seal. The total bill is esitmated at $1500 Canadian. Youch. I'm not sure if I'll proceed with the repair, given the age of the vehicle.

My car will go off gear when i brake hard and it takes a few seconds to pick up gear again


It sounds to me like your transmission fluid level is low, when you brake hard the fluid moves to the front of the pan and leaves a void for the filter to grab air instead of fluid. When you stop the fluid settles back and away you go again. This could cause premature transmission failure so check it soon and top it up ASAP. With the transmission cold the fluid level should be near the add mark, full mark only if the trans is hot.

Transmission slips after engine warms up


It isn't when the engine gets hot, it is when the transmission fluid gets hot that the slipping starts, due to wear of the clutches and gears inside the transmission.
First, check the fluid level to make sure it is full. If it is low, bring fluid level to full and see if that helps.
About all the owner can do with slipping automatics is trying a transmission fluid and filter change to see if transmission revives and stops slipping. The bottom pan is removed, fluid (about 6-8 quarts) is drained, and a new filter is installed before the pan is replaced with a new gasket, sealed up, and fresh fluid added. Sometimes it helps. Sometimes the transmission is worn too bad to help, and you are left with looking for a replacement transmission.
Check the fluid level first. Good luck.

TRANSMISSION SLIPS AND SHIFTS HARD, AUTOMATIC


Often the cause is low transmission fluid. Follow the instructions in your manual for checking it, because unlike checking your oil level, checking transmission fluid levels require that the vehicle is running.

Please, by no means do this check if you are uncomfortable doing it. Have a "gearhead" friend that you trust or a mechanic show you how.

Most manufacturers ask that you start the car, and while holding down the brake pedal, slowly shift through reverse and then all your forward gears, then place the car back in park.

Next (with the car running- CAREFUL!), find the transmission dipstick under the hood, pull it out, and wipe it off. Put the dipstick back in, pull it out and check the level. If it is low, you need to add some transmission fluid of the type specified by your manual into the dipstick hole (you will need an inexpensive transmission fill funnel), a little at a time, and keep checking it as described above until it is at the FULL mark.

It is important to note that the dipstick is marked FULL HOT (car is warmed up) and FULL COLD (car is NOT warmed up) because transmission fluid expands quite a bit and overfilling is bad for your tranny!

I own a Jeep with a Chrysler "straight six" engine (one of the best motors ever!) and my transmission slipped because of low fluid - I added a bottle of "transmission stop slip and stop leak" fluid to it and topped off the remainder with the proper type of transmission fluid, and now, seven months later, I do not lose any tranny fluid and it shifts great! The stop leak is more expensive, but IMHO it is worth the cost.

Please rate my solution when you get a chance!

Well, my transmission likes to slip majorly between 1st and 2nd gear. and if im just starting the car (like first thing in the morning), ill give it about a minute to warm up and then ill leave. well when...


After the engine reaches operating temp, on a flat level surface, check the fluid level in the transmission (running in park) If it's low, top it off. If it's full, chances are there is an internal seal that is allowing pressure loss, preventing the transmission clutches to fully engage. You could try changing the fluid and filter, adding lucas trans conditioner. That may help a bit but most times the only permanent cure is to rebuild/replace the unit. Don't expect "instant results" from the conditioner. often it takes a few days to work...it took a long time for the seal to wear.

I think I have a timing issue. My car takes a second to start up and the car jolts when it changes gears. Also, my steering wheel shakes left and right when I'm driving at low speed


Ok,

same car with the AC problem. Timing is not going to make this all happen.

  • If its jaulting as an automatic, through the gears, then probably check and change the fluid and the filter in the transmission. Usual jolting is from lack of fluid pressure, caused by lack of or blocked filter.

  • Start up could be anything from a weak battery to lack of fuel/choke. Try a new fuel filter, air filter element, check your oil and change the spark plugs.

(Symptoms of bad ignition timing are misfire and run on also extreme lack of power and rough idle. The car will also shudder and keep running a few seconds after the key is switched off.)

  • The steering shaking from left to right at low speed could be a few things. Is it only happening at low speed? Sometimes its hard to tell at high speed as it is happening so fast the frequency is almost unable to be felt. However when you brake it should be pretty strong if its a mechanical fault, ie disc warped or bent wheel.

MY CAR STARTS BUT I HAVE NO GEARS BUT WHEN JACK IT UP BOTH TIRES OFF THE GROUND THE GEARS WORK. WHEN I WAS DRIVING I LOST ALL GEAR


Do you have forward and reverse when the wheels are off the ground? It is possible you have lost hydrolic pressure. Check the fluid level by letting the engine warm up, applying the brake, and then run the gear selector through the full range of gears, pausing a few seconds in each gear. Put it back in park but leave the engine running. Then check the fluid level on the transmission dipstick, twice. If it is low, add some and that'll likely fix the issue. If it is full, then you probably need a new transmission oil pump.

Upon starting it takes a few seconds for the car to move once you've slected a gear.


I suggest that you check the transmission fluid level on the transmission oil stick and make sure that the fluid is red and up to the full line after the car warms up. Also you may want to get your transmission oil changed with a new filter screen by a trained professional at a dealership or transmission shop.

Car slips out of gear after the engine warms up


Ok this is an internal transmission problem, the 1st thing to do is check the fluid level in the trans, do this only on a HOT transmission otherwise you will overfill the trans and damage it more, if the fluid is full and clean then the trans will need to be torn down, but this does sound like a low fluid level problem.
