So I'm trying to change the trans fluid on my manual 1995 318ti (m42.) The problem is when I get my 17mm wrench on the bolt and turn counterclockwise it dose not budge, I've spent probably too much time on it getting pissed. I used so much force eventually the threads went from perfect to slightly rounded, even though I'm using the box end of a 17mm and it's not slipping.. It feels like the f*cking thing is welded into the trans. Is it reverse threaded? I eventually took out a pair of vice grips, determined to get the job done and I used both hands, vice locked in place, and I after probably 150 pounds of force the aluminum of the bolt is just shredding into ribbons of aluminum.. I just want to get this done over the weekend. I have a spare trans fill bolt (magnetic) ready to go in so I'm not worried about ruining the old one. Please any help I'm out of ideas... | | | 10-06-2018, 02:36 AM | #2 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Before you get the drain plug out, are you able to open the fill plug? It is not reverse thread. For extra leverage I'll use a long pipe or my jack stand handle since it's hollow. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org Last edited by 1996 328ti; 10-06-2018 at 02:43 AM. | | | 10-06-2018, 06:23 AM | #3 | Junior Member Join Date: Jan 2017 Location: FL Posts: 5 | Yes sorry I'm referring to my Fill plug. my jack only raises it enough just to squeeze under so theirs not much wiggle room but I'll try again tomorrow =( | | | 10-06-2018, 02:09 PM | #4 | Senior Member Join Date: Apr 2009 Location: TampaBay, Florida Posts: 104 | rounding my bolt I suggest you buy an LW10 vise grip (locking wrench) and add it to your tool arsenal. Try ebay. yes - counter clockwise, Lefty Loosey. | | | 10-06-2018, 06:10 PM | #5 | Junior Member Join Date: Jan 2017 Location: FL Posts: 5 | Thanks for your advice, I've been using these: https://www.irwin.com/tools/locking-...th-wire-cutter And as I've said even with it fully locked tight as possible I put all my weight into pulling with both hands with my knees locked on the front bumper so I don't slide. and I must be putting at least 150 pounds of force if not more (my shoulder are actually sore today) and the bolt will not move, even with the vice still locked the bolt will start to shred. It feel like the aluminum is too soft on the construction and it's just on too tight. I don't know I'f I can win at this point. I'd use a pair bolt extractors but there is no room to use a ratchet. | | | 10-06-2018, 08:17 PM | #6 | Junior Member Join Date: Jan 2017 Location: FL Posts: 5 | This is the most frustrating thing. No matter what I try nothing works, I swear someone must have used thread lock or welded it in. at this point it would be quicker to put a brand new transmission in. Guess I'm gonna give up on changing the fluid and drive it till it breaks. | | | 10-07-2018, 12:19 AM | #7 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Have you soaked it with PB Blaster? __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 10-07-2018, 12:59 AM | #8 | Senior Member Join Date: May 2013 Location: Seattle Posts: 513 | Pb blaster over night Torch to heat area Impact gun If that stuff doesn't work, forget about the fluid change. BMW uses "lifetime" oil anyhow..heh. | | | 10-08-2018, 12:32 PM | #9 | Senior Member Join Date: Aug 2009 Location: Georgia Posts: 595 | BMW uses "lifetime" oil anyhow..heh. Yeah right ! LOL. I have changed my 5-speed transmission fluid like 4 times already. Still shifts smooth at 280k miles. I used a six point socket to break it loose. Then just hand snug it tight. Do not overtighten. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 | | | 10-08-2018, 12:55 PM | #10 | Senior Member Join Date: Apr 2009 Location: TampaBay, Florida Posts: 104 | For BMW Automatic Transmission. After you drain & snug tite the bolt, remove the fill bolt and fill til it drips, then replace bolt. THEN start the car and get her to full temperature. the fluid is now low, because it has cycled. Remove fill bolt and I use my power brake bleeder to pump in more ATF til it just drips, replace bolt and wipe clean. She is NOW filled!

As I understand, atf will expand with temperature so I don't think it will be low. Now, if it's an automatic transmission, yes, it has to be in idle and up to 90F to complete the fill process. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 | | | 10-08-2018, 04:12 PM | #12 | Junior Member Join Date: Jan 2017 Location: FL Posts: 5 | Yeah, PB blaster didn't do the trick so I got the car off the stands since i need to use it today. My friend just opened up a shop with bays and more tools than I have, so I'll head there tomorrow. Thanks for all the response! | | | 10-08-2018, 04:37 PM | #13 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Quote: Originally Posted by Turkeyboyslim Yeah, PB blaster didn't do the trick so I got the car off the stands since i need to use it today.

I thought soaking in PB Blaster and walking away would do the trick. Good luck! __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
