    Hey, i’m trying to service my automatic transmission on my, 2011 e93/n55 right now. I have all the supplies and tools I need but before I do anything i’m trying to figure out how to drain my torque converter (TC) so i don’t mix the old and new fluids together further messing up the car. Any clue?

    Hey guys! I've been having this issue for a really long time now but still haven't been able to solve it. I recently replaced the Torque Converter as my car was jerking in lower gears while accelerating. Now that I've changed it, from speeds between 31 mph to 68 mph when I accelerate suddenly...

    Last summer I bought my 2nd e36, a 96 328i with a failed transmission. I fixed up a bunch of things on the car, found a auto trans for the right price and put it in. My first tranny swap. Engine always ran great. The car drives now, but makes a little whirling noise coming from the front of the...

    So today i was scammed. I purchased a 2000 328i Msport in what i thought was near perfect condition apart from the high mileage... Now to be fair this car was extremely well priced at 1.8k Nzd, almost too good to be true. I had checked out the car once before, i didn't test drive it. He...

    My vehicle is a 2002 BMW 325i with 110K miles on it. About a year ago I started to experience a hard engage when shifting into drive or reverse usually after the car had been warmed up and driven for a while. It was only happening about once a month until recently, it's been happening a little...

    Hello everyone. Just looked under the car and saw the automatic transmission cap leaking a very black oil. Although there is a green-yellow area visible around the cap, under the cap the liquid was very black, a few milliliters. Any ideas? Transmission torque converter? Engine oil or tranny oil?

    Hello, I am having some issues with my e53 6hp gearbox. Symptoms lurching into first gear Very very slight hesitation to go into reverse from drive and drive from reverse. But both fine from park. And finally a Goose honk/ turbo noise from the shifter area when under load. Then trans fail safe...

    Hey folks, So I have an 02 525i Auto E39. Build date 07/2002, M54 2.5L, ZF auto trans. She's my baby and last month the tranny took a dump. It's the ZF 5HP19 automatic trans (septronic). The front input shaft seal blew, spun the metal bushing behind it and it seized to the torque converter. The...

    Hello, Ok, my 2002 e46 330ci auto has decided to bite me in the @$$ just before Xmas! I have a "Cog" symbol warning light on the dash. I have no reverse gear and only 2nd gear which just idles along at low revs even when foot is down on accelerator. I have plugged my OBDII in and used an app on...

    Recently, I noticed strange rattle noise when driving my 2007 BMW 750Li. The noise sounds like something getting loose underneath the back seat. but when I sit on the back seat, the noise seems coming from somewhere underneath between the front seat and back seat in the center The noise will...

    I recently bought an 02 325I and upon replacing the transmission I found some one had replaced the 3 torque converter bolts with a cheap grade 3 bolt. SO I'm trying to find the pitch of thread and length of the OEM. I'm thinking its a 10mmX1.50 for the pitch by 2in in length?? Thanks for all the...

    I have 2002 325i Zf Transmission. I recently bought this car as a fixer upper as I am becoming interested in these cars. Initially the Bmw was throwing me the P0715 code (input turbine sensor) and nothing else. So I removed the pan and valve body and found out that the sensor wire was broken and...

    Hi, First time I post a question on the forum, I looked and search, but wasn't able to find the answer, I did find few pointers on what the issue is, but I need a very good way to explain this to my mechanic since I keep getting that the transmission is fine and if there aren't any ODBII codes...

    So I found a nice 325is on craigslist for $2400, but the seller had just replaced the front brakes and rear tires which puts me into suspicion that he may have been doing brake stands/ burnouts. By doing this with an automatic, will it damage the tranny, or is it all going through the torque...

    Hi All, I was hoping someone could help me out before I go off spending money on things. My CEL came on the other night on my '98 528i. The code was P0740, which is a Torque Converter Clutch Solenoid malfunction. This is the first fix I'll be attempting myself and I'd just like some second...

    Our 2000 540i, 194,000 miles. Car performs beautifully except for this problem we can’t figure out. Under very light throttle at about 1500-2000 RPM, once the car has upshifted to 4th or 5th, we get a ‘lurch’ and the tach jumps up about 250-300 RPM and repeats about once every 2-3 seconds...
  18. E60 / E61 (2004 - 2010)
    I just finished rebuilding my transmission (ZF6HP19Z) and valve body. GT1 shows the torque converter performing normal and I'm not getting any codes, but it just seems that the rpm is a little high at 70mph - about 2200. My feeling is that the clutch in the torque converter is not working, but...

    Hi, I have a 2001 BMW 330I with about 125K miles. Recently I was on the highway, I had been driving for about 15 minutes, and it felt like my left front tire blew a flat; rumbeling, pulled to the left. It happened twice in a matter of a few seconds. I pulled over, but the tire was fine...
