Where do I put the Lucas transmission slip liquid in my bmw 325i? There are places to put oil, anti-freeze, wiper fluid, however I cannot find where to add transmission fluid.

Pull the transmission & rebuild it

IT SLIPS --didn't need to ask that question

Slips-your done-internal damage

Change the fluid every 2 years-- you won't have that problem

Try to add LUCAS OIL transmission anti-slipp additive. It helps smooth the shifting. If this helps you need to replace transmission fluid with the filter and add fresh fluid with Lucas oil additive ..

check your rear main seal. Also try changing your trans fluid, trans filter, and your transmission pan seal. I recommend you put lucas transmission oil in it and a quart of the Lucas Stop Slip and leak sealer

Why do you want to add it? Wipe the dipstick on clean white paper towel or cloth. If there are no leaks and the colour is still fairly bright it should be ok. If there are no leaks and the transmission is slipping it needs to go to a dealer or tranny shop.

Are you sure you use the right type of fluid, and have you let it warm up and checked the level with the engine running?
I would only use the recommended oil suggested by BMW.

Try manually shifting it?
Also, is there any chance you disconnected a wire or hose to the transmission valve body when you had the pan off?
Or any chance you got some dirt inside?

have one myself w/over 400.000 miles suggest you change transmission fluid and filter,just add lucas transmission treatment to your fluid change. never had problems w.mine. but firm beleiver in lucas oil and transmission and fuel treatments. just trying to see how far i can go w/mine. the lucas treatment added to your fluid and transmission fluid and filter change frees up stuck valves in the transmission. sounds alot like you may have a stuck valve body in the transmission to me.pull your transmission fluid dip stick,this is going to sound strange but go with me for a second please, does the fluid smell burnt? do'nt be scared to put it on your finger and sniff it. if it smells like burnt expletitive,then it needs replaced and filter too. just please add lucas transmission treatment to your fluid change,you will not regret it. the treatment [lucas] will cost an extra $11.00 onto the fluid change,trust me, you will not regret it!fluid changes are a must for ford explorers 4x4 don't know why,but they demand baby formula. lucas,i've found is that formula. thank you for choosing fixya.com we are here 24/7 for you 7days

on the drivers side of the transmission under the car is a plug similar to a rear end in the older rear wheel drive cars bmw has
a lifetime tranny fluid setup so take out the plug and fluid should drip out its right behind the shifter cable if it dosent drip out youll need a pump to put it in you can get these at advance auto

it must be something to do with electronic control to gearbox ecu wireing i assume the replacement gearbox came with tourqe convertor a diagnostic check might be best option

when looking at the engine with the hood up, look to the right hand side for something that looks like this (#1 in the pic): http://www.realoem.com/bmw/showparts.do?model=ET37&mospid=47720&btnr=32_0957&hg=32&fg=20

it will be black in color, but don't confuse it with the oil filter housing. power steering reservoir will have a unique cap (#2 in the pic) that can be removed with your hand. the one that has the large nut on top is the oil filter. remove the cap and put in the correct fluid.

hope this helped.

go buy a bottle of Lucas transmission treatment, add it to the trans fluid, if this does not help with in a few hours of driving, your secondary is going bad.
