There are a few possible causes of transmission fluid coming out of a dipstick hole. The most likely cause is the vent hose might be clogged. In this case, you would need to clean out the vent carefully. Most people use a long piece of sturdy wire to remove the build-up. This isn't a permanent fix. It will have to be properly cleaned as soon as possible. If you are not able to do this yourself, you will have to take it to a repair shop. The repair shop also has the ability to flush your transmission if needed. This helps with clogging problems that the transmission might be having. Having a cap over the dipstick hole helps keep dirt and dust out which helps keep the tube unclogged.

The hole could simply be overfilled with fluid. Make sure you check the level of transmission fluid. If you recently purchased your vehicle used, the seller might have overfilled the dipstick hole with transmission fluid on purpose. Some dealers do this to mask transmission problems. It is a dirty tactic that some sells will resort to doing, but most do not.  A servo piston could be loose or missing. Make sure all of your pistons are intact and tight enough. You might also have kinks, clogging, or binds in your cooling lines.

This situation must be dealt with immediately. If fluid is coming out of the dipstick hole, it probably means you are currently low on transmission fluid. This would mean your car is low on coolants. Without coolants, your car's engine can overheat or your car can catch on fire. It has happened to many people. If you aren't able to find the problem and fix it, it is best to take it to a repair shop to be safe._

If you pull out the dipstick, it is supposed to have oil on it. If you are getting tranny fluid and are very sure of it being tranny fluid, then you need to get it into the shop to get it repaired. Hope this helps, good luck to you.

What a dumb-ass response, and solution! He meant tranny fluid is backing up the tranny fill tube! Not tranny fluid in his engine! And Yes, you might check for a clogged air vent or the transmission cooler (like a radiator) is not cooling fluid properly, It's getting hot and backing up the fill tube. Or you could just defeat the purpose of this forum and take it to the shop and tell them you have transmission fluid in your engine instead of oil and see what they tell you!
