i own a 2000 bmw z3 2.3 roadster. my dad and i were putting a new radiator in and we forgot to bolt up the transmission lines so when i turned it over, transmission fluid sprayed all over. we hooked it up and turned it over again, only to find out that it now will not go into any gear without slipping. by slipping i mean catching and releasing so the car kinda rocks forward a little and rolls back.i jacked the car up and crawled under it and took out the bottom plug to see if transmission fluid was in it and it poured out. i checked the other plug located on the side of it and that poured out too. ive also noticed that the transmission fluid bucket thing where you pour it in hasnt drank any down. the car only has 30k miles on it, so i dont suspect the transmission to be failing. any help would be great. Thanks!
Is the transmission light on? Its the toothed wheel symbol on the lower right of your instrument cluster These transmission are very sensitive to fluid level and fluid type, as they are lifetime fluids and are not supposed to be changed. sounds like you might bee in limp mode, this is where the transmission locks itself in 3rd gear and doesn't shift up or down. I'd the light is on, disconnect the battery for a few minutes, reconnect the battery, turn car on, let out warm up and go through the gears slowly without moving the car. let the car idle in each gear for at least 10 seconds. Even of this fixes it, i would try to put the correct fluid that you lost in the processes back in.
