My 1979 chevy bonanza 4wd. pickup has started blowing transmisssion fluid out the dip stick tube,after the truck warms up a few minutes.thank you albert blair

usually owners manual will tell you not to over fill the trans, check owners manual

Step 1: Start your car and warm up the engine.

Step 2: With the engine running remove the transmission fluid dip stick, wipe off the fluid and reinsert.

Step 3: Remove the dip stick and check the fluid level.

Step 4: If it is low stop the engine and add about a cup of fluid using a funnel into the dip stick tube.

Step 5: Restart the engine and recheck the fluid level.

Continue filling and checking until the dip stick shows it is full on the stick. Do not guess as too much fluid can be as harmful as too little.

Trans' may be already full. The dip stick is attached to the trans' pan corner and out of the way of rotating parts.

With engine idling, dip trans very quickly...fluid should be below lower mark if fluid is cold and just below the upper mark if warm.

You are going to need to have the transmission rebuilt.

It goes in the transmission dip stick tube. You may need a small funnel to fit the opening on the tube. Make sure the engine and transmission are warm and the engine is running when you check the fluid. Wait a minute after adding the fluid to check it so it can all drain down the tube or it will cause false readings.

There's no dip stick on your truck, transmission fluid get check at transmission pan, on drain plug on the center of it, will have a small hex screw, with engine running in park, remove center screw, if fluid comes out, level is good, if no fluid comes out, fluid will have to be pump up through there, hope this was very helpful.

Automatic transmition fluid is added through the dip[stick tube. You should use a funnel that is long with a small opening. Auto Parts stores carry funnels just for this purpose. Add small amounts and check the level frequently when adding fluid. the difference between low and full is usually about 1/2 of a quart. If you over fill an automatic its a pain to get the excess fluid out. Check the fluid regularly for a while and add as needed or take it to a mechanic and have them do it.

Sounds like the engine can't breath,
make sure pcv valve is good,or oil cap is vented.
your engine is building up pressure and has no where to vent,so it blows the easiest thing,the dip stick

the trasmission fluid leval may be low or your cluches are slipping. check the trasmission fluid leval with the engan wormed up and the trasmition in park pull the dip stike with yellow on it and check the level alsow smell the dip stick if it smells burnt the the tran fluid need to be changed.
if it is low put tranmition fluid in it by using a long funal and put the fluid in the tranmition dip stike tube. If the leval is full and the fulid is not burnt it might be trasnmiton cluches and the tranmition needs to be rebilt.

if the transmission is a manual there is no dip stick there is a plug on the top side of the gearbox which takes a large alan wrench remove plug stick finger in hole if you have fluid on your finger its full
