Most likely front transmission pump mounting gasket and the o-ring seal that go around the pump
and seal it to the case if this is a 1500 series truck. Requires the trans be removed and partially
disassembled. Parts probably run around 150 but the labour could be around 8 hrs or more.

All my transmission fluid poured out my car why driving what could be the problem


WITHOUT YEAR/MAKE/MODEL it is hard to be accurate with any help. The fluid may have leaked from a transmission line a transmission cooler...a cracked tank in the radiator... a front pump seal in the transmisson..... a cracked transmision case... a transmission pan/gasket etc

Where is the transmisson fluid filler?


You fill it thru the same tube you check it, the dipstick is between the overflow tank and the exhaust pipe in front of the master cylinder.

I have transmission leak coming from the front of my 1995 chevy with a 4L60e, i already changed the pan gasket


if your shure that the pan is not leaking i would check the front seal on the transmisson. if its the front seal there should be fluid leaking from the flywheel cover.

Have Kia Sedona 2003 Automatic with a leak that is either steering fluid or transmisson fluid, are these fluids the same colour?


In most cases Automatic Fluid (ATF) is used as hydraulic fluid for power steering systems, so, yes, they are the same fluid. To identify the origin of your leak, place some sheets of news paper under the front of the car and see where the oil drops collect. Look above that and identify whether it is nearer the transmission or the power steering system. You may also be able to see the origin of the leak from beneath the car with the front raised on ramps (not jacks).

The 4wd will not engage on 2004 tundra


you probably have a vacume leak , there is a control harness that runs from the front axle up on the transmisson , usually with 4 little hoses attached and it plugs in at the transmission, that is where the vacume comes from , that is where I would start

Transmission issue. I was going up a hill (IN WV)... and my engine started to smoke. When i pulled over and examined my car it was pissing transmission fluid. ..it was more so near the front of the engine...


In your comments you say front of engine then you say coming from between the engine and transmission. By your description of your engine starting to smoke it sounds like a sudden rather large leak that sprayed or splatter on your exhaust system where it immediately would cause a smoking condition, really only two places a transmission would have enough fluid pressure during a leak to send enough fluid in a short time to cause your experience, check for a Transmission Oil Cooler Hose and or your first thought a Blown Torque Converter Seal. Torque Converter seals usaully start with a slow leak at advance towards a larger leak over time but I have seen where a entire seal has become unseated thus causing a sudden and high volume leak. Check Transcooler lines and TC seal... Hope ths helps

To verify your issue the vehicle should be raised safely on an auto lift or a on recommended weight rated jack stands to preform a visual inspection for your leak.

Need to add transmission fluid to a 2004 Chevy Optra


It is annoying when people automatically assume there is a dipstick and that we are all dipsticks for not knowing. There have been a few cars that have come out on the market in the last ten years or so that have no dipsticks for the automatic transmissions. I also have the same issue with a slow leak from the line coming out of the rad. There is a spot on the front of the transmisson behind the rad hose where you can put in fluid. When you remove this bolt, fluid should come out..if not then you need to add some. To add it jack the front of car and using a funnel add some fluid until it pours out when the car is level. This may take several attempts. If you over fill it just let some drain out into a pan until your at a trickle then put the plug back in. This is the only solution I was able to come across for this. It seems to be a common issue with these cars as it the problem of the lines rusting out and into the radiator making it necessary to replace the lines and rad,
