I have a 96 BMW with 108,000 miles on it. Should I flush the transmission fluid? Or will the transmiss. break?

Question

I never changed the fluid in the past.

PHILLIP S- I have a an 1996 840CI with an Automatic Transmission

Answer 1

It will not hurt the trans to change the fluid. Get a manual and follow the instructions.

Answer 2

There were 2 or 3 types of A.T. found in the various models of BMW in the mid 90s. Which BMW and which Trans. do you have? Many of the Auto-transmissions came with a very expensive Permanent, never change AT Fluid. These ATs have no filler tube and no drain plug by which to empty and refill the AT. BMW has changed its original philosophy about never changing AT Fluid. BMW now says the Permanent ATF s/b changed at every 100K miles using AT-Fluid Type 3. The procedure to do this is very challenging in how to get the old AT Fluid out and the correct amount of new AT Fluid in. A BMW dealer should have an instruction sheet about how to do this. The transmission should not break if you fail to change the AT fluid. Do you have any warranty still on your car?

Answer 3

i wouldn't. trans fluid is a high detergent oil that cleans crud from various trans components. the detergent in old trans fluid gradually breaks down and does not clean as well. putting fresh trans fluid in a car w/ 108,000 miles will uncake alot of stuff and cause your trans to fail.

Answer 4

If the fluid is a brownish red or darker yes. Then again it has a million miles on it, so I would just save yourself the money.

Answer 5

It depends. If the fluid has never been changed I wouldnt change it. It will probably cause more problems

Answer 6

if it is black and smells burnt leave it alone but if it has a lil red tint and dont stink i would do it-should do it every 30k
