i am sitting with a problem i have recently bought a e30 bmw 93 model with automatic transmission.
Yesterday i started the car and it didn't want to go into reverse, so i pushed the car out and took a drive. When i started her up again she went into reverse, i put the car back into drive and drove off but it didn't want to shift to 2nd gear. i also tried going through the 1st 2nd and 3rd gear but nothing happend. its almost as if the car does not register it needs to change. what is the problem. where do i start????

Check the trans fluid and change the filter other then that i don't have much else. when it does shift is it a hard shift? Does it make any noise?

time to start thinking of a 5spd swap.

either the valves are starting to get gunked up and need to be cleaned (oil and filter change) or the pump and planetary gears are starting to show their age

Does not sound cheap. Try a good indy transmission shop first.

Any idea how much a garage will charge for changing the transmission oil and filter.

Usually not much but diy will save some money and its fairly easy

I found changing the filter and fluid very, very easy.

step one, get a new filter and transmission pan seal.
step 2, drain the transmission by removing the drain plug
step 3, remove the fluid pan off the bottom the tranny, i think htere are 6 screws. (mine were really rusted so i ordered new ones)
step 4, remove the old filter, only 1 alen key screw holding it in
step 5, clean off the magnets in the bottom of the pan, install new filter and seal and put the pan back on.

get new fluid and fill it up.

super easy.

its about as easy as changing the oil, except with a few more screws.

What are the magnets in the trans pan for is it to keep any metal pieces( god forbid there are any) from flowing through?

the magnets are for small shavings/filings that accumulate in the fluid. My car was very neglected and when i changed my filter i had a significant amount of filings on the magnets. my fluid was also a dark black sludge.

the PO really neglected the car leaving me with alot of work todo
