Does transmission have a drain plug?
If it is a manual transmission, it will typically have a large drain plug on the bottom of the transmission housing. If it is an automatic transmission, it will either have a large drain plug on the housing, a drain plug on the transmission pan, or the transmission pan will need to be removed.
Can you drain transmission fluid without dropping the pan?
Performing a transmission fluid change requires a little more precision than changing motor oil. But, if you know how to remove a drain plug, then you should be able to change transmission fluid without removing the pan. However, understand that this method will only allow you to change about 25 percent of the fluid.
What is a transmission pan?
What is a Transmission Pan? The transmission pan and gasket keeps automatic transmission fluid in the transmission, where it belongs, and off the ground. Repairing a transmission pan leak is often as easy as replacing the pan gasket, assuming the pan itself remains free of damage.
Where is the transmission filler plug?
Most of the time, the filler plug is a large bolt located about halfway up the side of the transmission.
What is the easiest way to drain transmission fluid?
The trick on how to drain transmission fluid is to work from the top, sucking out the old fluid up through the filler tube. Then refill with fresh fluid. A hand-operated vacuum transmission fluid pump makes the job simple and clean. You can remove one-third to one-half of the fluid from the transmission at a time.
Why is my transmission pan leaking?
The most common source of a transmission leak due to faulty installation is from the transmission pan. The pan is not mounted correctly or incorrect bolts are used to secure it. Something as simple as these bolts will make transmission fluid leak from the pan. Hopefully, the bolts just need to be tightened.
What happens if you put too much transmission fluid in a car?
If you add too much transmission fluid, you will notice that it may foam, and that can bring about erratic gear shifting. Some other problems that may arise include oil starvation and transmission damage. Adding too much transmission fluid can also cause early failure and damage of parts as result of excess pressure.
Why don’t they put a drain plug under the transmission?
The logic is that the design is not geared toward DIY repairs. Professional mechanics have lifts and special transmission drain/support rigs that can be wheeled directly beneath them. They don’t need a drain plug and in fact, since they change the filter or clean the screen during every service, a drain plug is superfluous.
Why do you have to remove the drain plug?
Removing the drain plug is a method to force complete removal of the pan and a proper clean. This also allows the service person to spot abnormal wear and advise the owner so that it is fixed before the transmission lets the owner down somewhere.
Do Trans fluid drains need to be welded?
The trans with drains seem to be the ones that have no pan and the assembly is cast rather than sheet metal. On the sheet metal ones, it would be an extra operation to weld the threads on. Then there would still be that hump in the middle so all the fluid still would not come out.
