trany slipping
hey guys i just bought an 03 x5 about 4 months ago its got 90000 miles on it
about 4 days ago i noticed only in the morning even after warning it up when i shift into reverse or drive it takes like 5-10 seconds for it to ingage into gear
the enigine just revs up but once it does ingage
it shifts great and runs great for the rest of the day
also i noticed that it doesnt do this in stick shift mode
i called the used car dealer that i bought it from and got dicko from him saying my 3 months are up blah blah blah
i tried to check if it was low on trany fluid but theres no dipstick
any body have any ideas or had this experience please help
