Mein Auto: 01 740il
New owner, 01 740il hard shifts

Hello and thanks for reading. I was given a 01 740il with 200500 miles. It was taken car of very well. I figured with my luck it would not be long before I ran into a problem, not to mention the milage and year I knew it was only a matter of time. Today I backed up, out it in drive and started to get hard shifts into frist and sometimes other gears. Shifts down fine and sometimes there is no problem up shifting at all. This is likely blasphemy to you guys but all along my plan was deive it until she has nothing left to give. If I can get 25k miles I think I did great. So question is how serious is this problem? I know of course it's not good but can I limp it along? Other then shifting hard (just started happening) runs perfect. Any and all suggestions welcomed. Thank you.

There are 3 quick and cheap "fixes" for transmission issues on these, and when they don't work it's either time for a new transmission or let it die.

Change the fluid and filter. Just let it drain and refill it though, don't do a "flush". With your kind of mileage you should probably start with just the fluid and drive it 5-10K miles and then do the fluid and filter.
And again because of your mileage, changing the fluid will likely remove some grit that actually helps the transmission work so you'll need to add some "Dr Tranny".
Lastly, this may sound weird but a new battery may make a difference. The computer that controls the transmission is very sensitive to low voltage.

Not nearly the cost of a transmission rebuild but certainly more than the 3 above would be to rebuild the valve body.

Welcome to the 'fest! And good luck.

Several years ago I experienced the same problem. After jacking the car up, I proceeded to add transmission fluid and Dr. Tranny. Had to use a cheap o pump from Harbor freight to get the fluid in. I had to shift gears has well and was surprised to have added 2 quarts of transmission fluid to my tranny. There were no leaks so where did that fluid go. Anyway long story short, I have not had any more hard shifting problems. I had plans of going back in and changing the filter b ut felt since my problems were gone don't press my luck.

Hi guys, Please tell me to piss off I'm hijacking the tread . I think I have the same problem and would rather not spam the forum with similar questions (if the op doesn't mind) .

I too have just acquired a 740 but year 1996. I assume by hard shifts the op is referring to it jaunting/thudding between gears and generally not being smooth. Mine seems to do this too, and almost hits a neutral like state between some gears for a brief second which causes the jaunt/thud. Putting it into or out of gear is fine. My battery is brand new. I'm tempted to check the oil level but wow does it seem quite complex on these cars (I'm used to Jappas). Is the oil top up or replacement the best place to start?

Cool forum by the way, and what a nice car the 740 is

Hey CaMoE38, piss off and quit hijacking threads
Yep! Doesn't matter what the car is, transmission fluid breaks down and burns up and should be replaced at regular intervals (30-100K miles depending on who you ask).
